i understand ketones in urine  is due to dehydration but what is happenin to the body to produce the ketones?

ketones are parts of lipids catabolism.in a normal body they are converted to amino acids and glucose and they are picked up from blood.but if they produced very much they may appear in the urine thet in this time urine smells bad that called "dead mice smell).this event occure in the diabetic ketoacidosis that in it because of insulin deficincy glucose level boosts in the serum and it converts to ketone bodies that go in the urine.in any stress imposed on body like dehydration that sympathetic system become hayperactive it cause to increase in glucose catabolism that produces ketones.

Because these sugary treats are expelled from your body through urine, feces and your pores.  Drink more water if you want to change your urine.  You should anyway if your smelling your urine that strongly whether it be sweet or sour.  Your kidneys and bladder will thank you.

I won't answer this completely, because it looks very much like homework. \n\nI will say that an Aldehyde and a Ketone will yeild different degree alcohols. Reactions that yeild an primary alcohol from an Aldehyde would yeild a secondary alcohol from a ketone. Reactions that yeild an secondary alcohol from an Aldehyde would yeild a tertiary  alcohol from a ketone.

It comes from the carbohydrates we eat.\nFor example: \n1. from honey \n2. from sugar\n3. from bread\n4. from syrups.\nIt may come also from internal sources like from liver glycogen (this word means that it can generate glucose), from lactate (through the "reverse" of glycolysis), from glycerol that comes from tri-glycerides (fats and oils), from glucogenic amino acids such as alanine. \nOne of the most beautiful and amazing metabolic web is the use and formation of "glucose"!

Well, this condition is checked for and measured in the laboratoy by screening and measuring acetones/ketones in the blood. Acetone/Ketone levels increase when stored fats are metabolized at an accelerated rate, known as "acidosis". The pH of the blood decreases. The real hint here is "Acetone", which is an acid.

The ketogenic diet is a treatment for epilepsy that relies on inducing a state of ketosis. The diet prescribes foods high in fat, and heavily restricts carbohydrate intake. As fats become the body's primary source of metabolic energy, ketones accumulate in the brain, which can alleviate epileptic symptoms. The diet is more effective in children than adults, particularly when anticonvulsant drug therapy is ineffective (20%-30% of patients) or contraindicated.\n\nThe diet provides 3-4 grams of fat for every 1 gram of carbohydrate, calling for such foods as high-triglyceride dairy products (butter, cream, mayonnaise) and peanut butter. Carbohydrates, found in breads and starches, are eliminated from the diet, and liquid intake is often restricted as well in order to aid ketone accumulation.

They call it PKU because saying "phenylketonuria" over and over again is a mouthfull.  The "uria" ending at the end signifies that phenylketones appear in the urine.  People with PKU also usually have phenylketonemia (with the "emia" ending meaning that phenylketones appear in the blood).

thanks to God there r more urea than amino acids in our urines.otherwise we will face kidney failure very soon.amino acids are deaminated(removal of the amino group) to release ammonia.the ammonia is coverted to urea through the ornithine cycle while the keto acids(amino acids that have their amino group removed) can be metabolised.urea is excreted out of our body through kidneys via active secreation into the distal convoluted tubule.

Are you Diabetic? Have you had a recent "Dipstick Urinalysis"? If so, than Diabetics often demonstrate elevated urinary Ketone levels prior to an elevation in serum levels. You can also have false-positive results in dehydration or in the presence of levodopa metabolites, mesna (sodium mercaptoethanesulfonate), and other sulfhydryl-containing compounds.  Why don't you consult your doctor and get the complete formula or visit the Medical library reference section.

False. One glucose enters glycolysis. That glucose is then converted to 2 pyruvate which then go onto become Acetyl CoA to enter the Kreb cycle. The Kreb cycle then spins twice creating CO2, 2-ATP, and 6-NADH & 2 FADH. These protons are then sent to the electron transport chain to produce ATP.

A ketone is RCOR'\n\nFor completeness, the others are:\n\nROR' - ether\n\nRCOOH - carboxylic acid\n\nRCOOR' - ester

You may find this hard to believe, but you have to drink water..... and lots of it . In order to de-toxify your body, the kidneys have to be flushed, and water is the natural way to get your kidneys to produce. Good luck !

This is a rather complex process. First of all urea are made in a process called deamination, this occurs in the liver. Excess proteins that have been eaten by the human are broken up and converted into urea. \n This then enters the blood and is transfered throughout the body(even our sweat contains urea!).\nAs blood passes into the kidneys, it's filtered there so urea is separated from the rest constituents of blood.\nFrom the kidneys urea,dissolved in water( now called urine) is transfered via the ureters to the bladder where it is stored until excreted.

Water, urea, sodium, potassium and metabolized waste products.  Urea is the main reson we have to pee, it is the way we get rid of excess nitrogen from breaking down amino acids.  Many drugs such as tylenol are excreted in the urine also, which is why you have to take more every 4 hours.

Sugars in the diet.  Next, would be gluconeogenesis from the liver.

Drinking that much water will not stop you from going into ketosis.  You are probably not feeling well because of the change in your diet.  Changing from a high carb diet to a low one will bring a bout withdrawal.  It is a very temporary situation and you will be through it soon.  Keep drinking at least 64 ounces of water daily and keep going on the low carbs.  You will be amazed at how fast the weight will come off.

The kidneys serve two major functions: they keep the salt content of the blood constant, and they filter waste out of the bloodstream. So, the main components of urine are (salt) water and waste products. The major waste product from cells in the body is ammonia, and the major waste product from blood is a broken form of heme called bilirubin. In the liver, each of these is converted into a less hazardous form: ammonia is converted to urea, and bilirubin is degraded to urobilins. Salt, water, and urea are all colorless, but urobilins (which come from degraded pigments) are yellow. So, if you drink a lot, your urine will be more dilute and clearer, and if you get dehydrated, your urine will contain less water and be darker yellow.
