True or false? Do all Lipids contain Fatty Acids?

Hi Danette.  This would be a false statement.  Examples of lipids that do not contain fatty acids include cholesterol and vitamin E.  Fatty acids are lipids, but not all lipids are fatty acids.

There are a huge number of studies that are providing at least some evidence for the value of omega-3 fatty acids in treatment of epilepsy, prevention of Alzheimer's disease, stroke, cancer, diabetes, and heart disease, among other conditions. So far the research is just suggestive, but this appears to be a very promising nutrient.

All organic acids have a carboxyl group (-COOH) in them.

Fat is normally thought of as triglycerides, like lard, formed in the body as a form of storage.  Any excess food whether carbohydrate or protein is converted to fat.  Cholesterol is a minor component of animal fats, and is present in all animal cells.

Vegetables contain all of these organic compounds in differing amounts.  Carbohydrates as both sugars and copious amounts of cellulose.  Proteins in the cells, but not generally as large structual components (obviously no huge protein sinks like muscles.)  Lipids as cell membranes etc....  All living things have nucleic acids, even viruses.

oleic acid - and a movie\nA desperate father discovered that this oil can clear the fatty acids that are responsible for Adrenoleucodystrophy (ALD), a genetic disease that progressively destroys the brain of young boys.\nWithin a year children are paralyzed, blind, unable to speak. It is invariably fatal. \nThe disease must be identified genetically so that treatment can begin before symptoms start.\nIt is also a movie with Susan Sarandon and Nick Nolte\n\nthe full description is at this BBC news article.\nhttp://news.bbc.co.uk/1/hi/health/3907559.stm

Saturated Fatty acids are long chains, which means they can pack more closely together and tend to be solids at room temperature.\n\nUnsaturated fatty acids have double bonds that lead to 'kinks' so they are more likely to be liquids at room temperature.

It has to say partially hydrogenated to make it a trans fat....Soybean oil is not the healthiest oil (flax oil and olive oil are)....but if the ingredients list soybean oil and NOT partially hydrogenated....it is not a trans fat.

no-you would die long before that! Fat is essential for our survival. It's found in places you may not be aware of. It's part of: \n\n\nevery cell membrane \nsome hormones and prostaglandins (hormone-like substances) which regulate many body functions \nnerve sheaths (nerve coverings) \n\nFat also plays an important role in keeping our bodies healthy. For example: \n\n\nA layer of fat surrounds each organ (such as your heart, liver, kidneys, etc.), protecting and cushioning it against impact during sports or accidents, to name a couple of benefits. \nFat helps maintain normal body temperature. \nFat provides us with a supply of stored energy, which can sustain us if food is not available. \n\nIt is dangerous to eliminate all fat from your diet. Certain fats, essential fatty acids, can only be obtained from foods. These are incorporated into regulators of specific body processes, such as blood pressure. Dietary fats are also required to absorb vitamins A, D, E, and K. These nutrients are vital to our vision, bone formation and maintenance, blood protection and clotting, and nerve development, and can act as a defense against oxidation. Without fat, we would be, well, a mess. Long before your body could have 0% fat your vital organs would shut down and you would die. \nThe lowest possible fat percentage a person has achieved was 3% for a male professional body builder.

Yes and No...\n\nAll Organic Compounds contain Carbon, but not all compounds containing Carbon are Organic.\n\nas quoted from my source, listed below...\n\n"An organic compound is any member of a large class of chemical compounds whose molecules contain carbon, with the exception of carbides, carbonates, carbon oxides and gases containing carbon.The study of organic compounds is termed organic chemistry. Many of these compounds, such as proteins, fats, and carbohydrates (sugars), are also of prime importance in biochemistry.\n\nThe dividing line between organic and inorganic is contended and historically arbitrary; generally speaking, however, organic compounds are defined as those compounds which have carbon-hydrogen bonds, and inorganic compounds, those without. Thus carbonic acid is inorganic, whereas formic acid, the first fatty acid, is organic, although it could as well be called "carbonous acid" and its anhydride, carbon monoxide, is inorganic"

Neither.  As a chemist who spent 30 years in the fat and oil industry I've seen this battle from all aspects.  Butter is undesirable because it contains many fatty acids that are foreign to the human body.  research has shown that butter contains over 200 fatty acids, including trans fatty acids that arise in the rumen of the cow from bacterial action.  Most margarines are made from partially hydrogenated soybean oil.  This source has come under severe scrutiny because of its trans acid content and also due to the fact it raises serum cholesterol levels.\n\nThe only safe margarines are the recently introduced ones that contain no partially hydrogenated oils.

Fat is one of the three main classes of food. It has many meanings, and the only good description is in technical terms. There are triglycerides, fatty acids, sterols, but "fat" may also refer to adipose tissue.\n\nThe main constituents of both animal fat and vegetable oils are triglycerides, that is glycerin molecules with three fatty acids attached. Nutritional fat is a mixture of many types of triglycerides, which differ in the length of their fatty acid chains, as well as the number and position of single and double bonds between their carbon atoms. Fat molecules contain only oxygen, hydrogen, and carbon atoms.\n\nVitamins A, D, E, and K are fat-soluble meaning they can only be digested, absorbed, and transported in conjunction with fats. Fats are sources of essential fatty acids, an important dietary requirement.\n\nFats play a vital role in maintaining healthy skin and hair, insulating body organs against shock, maintaining body temperature, and promoting healthy cell function. They also serve as energy stores for the body. In food, there are two types of fats: saturated and unsaturated. Saturated fat is a sort of a straight chain of carbon connected or bonded with 2 molecules of hydrogen. At the very beginning of this chain is a molecule of oxygen and a molecule of hydroxide. Unsaturated fat is the same thing with one major exception; some of those carbon atoms are not bonded with two hydrogen atoms so it becomes a very "fluid" state. Fats are broken down in the body to release glycerol and free fatty acids. The glycerol can be converted to glucose by the liver and thus used as a source of energy. The fatty acids are a good source of energy for many tissues, especially heart and skeletal muscle.\n\nAdipose tissue\n \nAdipose, or fatty tissue is the human body's means of storing metabolic energy over extended periods of time. Depending on current physiological conditions, adipocytes store fat derived from the diet and liver metabolism or degrades stored fat to supply fatty acids and glycerol to the circulation. These metabolic activities are regulated by several hormones (i.e., insulin, glucagon and epinephrine). The location of the tissue determines its metabolic profile: "Visceral fat" (around the abdomen) is prone to lead to insulin resistance, while "peripheral fat" (around the limbs) is much more harmless.\n\nMetabolism\n \nThe metabolism of lipids is a closely regulated system in virtually all lifeforms. It is affected by a variety of enzymes and, in higher organisms, regulated by hormones. Research is ongoing on the relative influence of various hormonal regulators on the anabolism (production) and catabolism (breakdown, also termed lipolysis) of fatty molecules.\n\nA subject of particularly close study is cholesterol, levels and types of which are influenced by the fatty acid metabolism and is known for its role in development of nerve cells atherosclerosis. Thus the suggesting that fat people are more sensitive to pain, particulairly in their abdominal region.\n\nAdipose tissue in detail. \n\nAdipose tissue is an anatomical term for loose connective tissue composed of adipocytes. Its main role is to store energy in the form of fat, although it also cushions and insulates the body. It has an important endocrine function in producing recently-discovered hormones such as leptin, resistin and TNFα.\n\nAnatomical features\n\nAdipose tissue is primarily located beneath the skin, but is also found around internal organs. In the skin, it accumulates in the deepest level, the subcutaneous layer, providing insulation from heat and cold. Around organs, it provides protective padding. It also functions as a reserve of nutrients.\n\nIn a severely obese person, excess adipose tissue hanging downward from the abdomen is referred to as a panniculus (or pannus). A panniculus complicates surgery of the morbidly obese, and may remain as a literal "apron of skin" if a severely

I assume you mean triacylglycerol. The exact answer depends on the nature of the acyl groups, but it will be glycerol and carboxylic acids.\n\nXC(O)OCH2CH[OC(O)X]CH2OC(O)X + 3H2O = 3XCOOH + HOCH2CHOHCH2OH\n\nIf X = alkyl or alkenyl then you'll get fatty acids, as mentioned in a previous answer.

Some do....Some consist completely of single bonds between the carbon atom but some have double bonds reducing the number of hydrogens that are present. \n\nMolecules without those double bonds are called saturated.  \nMolecules with those double bonds are called unsaturated.  \nMolecules with more than one of those double bonds are called polyunsaturated. \n\nThe difference between these molecules is this. Stearic acid has all single bonds. It is saturated and any fat made just from stearic acid will be a saturated fat. The other three have at least one C-to-C double bond. They are unsaturated and any fat (or oil) made from them will be unsaturated. Fats made from linoleic acid and/or linolenic acid have the added distinction of being polyunsaturated fats or oils because they have more than one double bond.

Saturated fatty acids have no double bonds between the carbon atoms of the fatty acid chain (hence, they are fully saturated with hydrogen atoms). There are several kinds of naturally occurring saturated fatty acids, with their only difference being the number of carbon atoms - from 1 to 24. Some common examples of saturated fatty acids are butyric acid with 4 carbon atoms (contained in butter), lauric acid with 12 carbon atoms (contained in mother's milk, coconut oil, palm oil, and cocoa butter), myristic acid with 14 carbon atoms (contained in cow milk and dairy products), palmitic acid with 16 carbon atoms (contained in meat), stearic acid with 18 carbon atoms (also contained in meat).\n\nFat that occurs naturally in living matter such as animals and plants and that is used as food for human consumption contains a varying proportion of saturated and unsaturated fat. Foods that contain a high proportion of saturated fat are butter, ghee, suet, tallow, lard, coconut oil, cottonseed oil and palm oil, dairy products (especially cream and cheese), meat as well as some prepared foods.

It may be worthwhile to have your Essential Fatty Acid levels tested.  These 'good fats' are commonly deficient or out of balance and can have a significant effect on skin health.\n\nYou will need to find a professional that specializes in nutritional assessment to get this tested, such as; some Chiropractors, most Naturopathic Physicians, any Certified Clinical Nutritionist (CCN) and a few Medical doctors.\n\nBest wishes and good luck!

Partially hydrogenated oil contains some trans fats.  The hydrogenation of oils will produce some trans fats.\n\nYou have a sharp eye.  The new FDA regulations are a bit 'phony' because if the level of trans fats is less than half a gram, they can say on the label "No trans fats".  You found a way to detect this 'lie'.  Congrats!
