Is a saturated fatty acid considered an organic compound?
488477
Yes it is.  A fatty acid is considered to be a carboxylic acid (organic acid).  Carboxylic acids contain carbon and oxygen.  Since organic chemistry is simply the discipline about the chemistry of carbon and hydrogen, then the fatty acid is organic.

Saturated Fats are completely "saturated" with hydrogen, meaning, there are no double bonds.  The fact that there are no double bonds allow it to pack very densely, and thus at room temperature, they will be solids.  Compare this to unsaturated fats, which do have double bonds, and because of this, cannot pack as tightly at room temperature.  These will be LIQUIDS at room temperature.\n\nWhat does this  mean?  Saturated fats are less fluid, and unsaturated fats are more fluid.  So a region of a membrane with more unsaturated fats will be more fluid, and less unsaturated fats will be more rigid.

Esterfied hydrocarbon oils can be both plant and animal based.  If the hydrocarbon is unsaturated (ie it contains one or more double bonds) than most likely it's plant based.  Saturated fats come from animals and contain no double bonds.

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

One could argue that chlorophyll is an organic or an inorganic compound. Because it has carbon bonded to hydrogen, C-H, it is organic. It is true that it contains magnesium, but magnesium is one inorganic ion among many atoms. On the other hand, the magnesium ion is the most important component, because magnesium mediates photosynthesis, whereas the organic porphyrin ring simply modulates the electronic environment of magnesium.

Lipids are generally classified as simple lipids,compound lipids and derived lipids.\n\nA)Simple Lipids: ester of fatty acids with alcohol\n -There are 2 groups of simple lipids:fats & waxes.\n  1)Fats: esters of fatty acids with glycerol\n  eg.triacylglycerols\n\n  2)Waxes: esters of fatty acids with long chain alcohols \n  other than glycerolseg.mycricyl palmitate,Vit. A & Vit. D\n  esters. \n\nB)Compound lipids:contain grps in addition to an ester of a fatty acid & with an alcohol\n  -There are 3 groups of compound lipids\n  1)Phospholipids: glycerol esters of fatty \n    acids,phosphoric acid & other groups containing \n    nitrogen eg.phosphatidyl choline\n\n  2)Cerebrosides: compounds containing fatty acids,a \n    carbohydrate and nitrogen moiety eg.galactocerebroside\n\n  3)Sphingolipids:compounds containing fatty acids,nitrogen \n    moiety & phosphoryl group eg.sphingomyelins\n\nC)Derived lipids:substances derived from neutral lipids or compound lipids eg. fat soluble vitamins,sterols.

fatty acids are normally called alpha #. This means that there is a double carbon-carbon link on the # carbon from the begining of the molecule.\nAs fatty acids are long molecules, if the the doble link is near the end, they are called omega # fatty acids.This means that the double carbon-carbon link is on the # carbon from the end of the molecule.

Organic Nitrates:\nOrganic nitrates have been used for more than 100 years, and are still used in the treatment of angina pectoris.\n\nThe most commonly used nitrates are: glyceryl nitrate (GTN), isosorbide dinitrate (ISDN) and isosorbide-5-mononitrate (5-ISMN). All of these compounds contain one or more nitrate functional groups, ONO2, in their chemical structure.\n\nAnother series of agents, the organic nitrites (e.g. amyl nitrite and isobutyl nitrite) that contain the nitrite functional group, NO2, and the nitric oxide (NO) containing compounds (e.g. nitroprussides) are often classified as organic nitrates, even though they differ in their chemical structure, because of the similarities in pharmacological effects.\n\nAll these agents are known collectively as nitrovasodilators.

There's a problem with your nomenclature.  Octadecane is a straight-chain alkane with the formula, C18H38.  A carboxy group can only be attached at either end, so the name octadecanoic acid (aka, "stearic acid") requires no number to say where the acid group is.  Besides, it couldn't be at the 9 or 10 positions, anyway.  What do the "9" and "10" mean in your question?

Conjugated linoleic acid or CLA refers to a group of positional and geometric octadecadienoic acid isomers of linoleic acid. CLA is not a single substance. In contrast to linoleic acid, all the CLA isomers have conjugated bonds. In an unsaturated organic compound, two double bonds separated by a single bond are said to be conjugated. \nThe Basics. CLA is a newly discovered good fat called "conjugated linoleic acid" that may be a potent cancer fighter. In animal studies, very small amounts of CLA have blocked all three stages of cancer: 1) initiation, 2) promotion, and 3) metastasis. Most anti-cancer agents block only one of these stages. What's more, CLA has slowed the growth of an unusually wide variety of tumors, including cancers of the skin, breast, prostate, and colon.(1)
