Pentane is found in distilled alcoholic beverages and hop oil. It is elevated in breath of people with heart failure and with schizophrenia.
acyclic alkane, clear colorless liquid with a gasoline-like (petroleum or starter fluid) odor, less dense than water and insoluble, hence floating, in water. Vapors are heavier than air.

Comments
Trimethylglycine (TMG) is a molecule which, structurally, is the amino acid Glycine with three methyl groups attached to it. It was originally as 'betaine' as it was the first dietary betaine discovered from Beet Root (Beta vulgaris). It is an ‘osmolyte’, a molecule that regulates water balance in cells, and protects cells, proteins, and enzymes from environmental stress (eg, low water, high salinity, or extreme temperature). It is also a methyl donor, participating in the methionine cycle—primarily in the human liver and kidneys. Inadequate dietary intake of methyl groups leads to hypomethylation in protein and fat metabolism. If disturbed, it may contribute to various diseases, including coronary, cerebral, hepatic, and vascular diseases. Betaine has been shown to protect internal organs, improve vascular risk factors, and enhance performance. Besides beets, TMG is commonly found in our diet in whole grains, spinach and shellfish. Betaine may cause fish odor in some cases (for example, if an individual with Homocystinuria on betaine therapy) leading to excessive production of dimethylglycine or trimethylamine. 2-aminoacetophenone (2AA), is an intermediate metabolite in the biosynthetic pathway for quinazolines, a pathway branching from the tryptophan catabolic pathway. Forms yellow to yellow-brown liquid with grape-type odor. This compound is related to methyl anthranilate which causes the foxy aroma (musty odor and flavor of wines) in grapes of non-vinifera varieties, but it may also lead to naphthalene-like odor. It can be detected in the breath of cystic fibrosis patients infected with Pseudomonas aeruginosa and, in smaller amounts, in healthy people - after eating corn chips, canned tuna, egg whites and some types of beer. 2-aminoacetophenone is the principal odorant responsible for the characterisitic taco shell odor of bat roosts (Tadarida brasiliensis mexicana). 2-aminoacetophenone secreted by Pseudomonas aeruginosa facilitates attraction to food for several fly species including Musca domestica, Ceratitis capitata and Drosophila melanogaster. Linear Formula H2NC6H4COCH3, Molecular Weight 135.16, CAS Number 551-93-9. Strong distinctive smell that's somewhat swampy/musty, salty and oily/rancid butter-like. Dogs, among many other animals, produce oil that gets attached to hair follicles. Water activates volatile chemicals. "Wet Dog Smell" is more common in hunting and cold-weather breeds, and less common in other breeds. Some people (their hair) may also emit a similar scent. Wet dog odor consists of many notes, some of which are actually pleasant, but they are overpowered by others that are not. It is a combination of sulfur, musty and fecal odors. Benzaldehyde smells like almonds or cherries. Phenyl acetaldehyde's smell is fresh, sweet and strong, like rose to hyacinth and lilac. Acetaldehyde smells like roasted nuts or dried out straw. Phenol (present in human and animal waste) has a distinct odor that is sickeningly sweet and tarry. 2-Methylbutanol smells like alcohol. 3-Methyl-1-butanol odor is more like whiskey. P-cresol is a major component of pig odor and human sweet attracting mosquitoes. It is present in manure. Its smell is coal-tar like. Dimethyl sulfides have a cabbage-like smell. It's a compound in rotting meat odor attracting flies. 1-Octen-3-ol has green, moldy and meaty smell, also attracting mosquitoes. It is present in spoiled wine and some mushrooms. 2-nonanone and 2-nonenal are components of tobacco smoke. nonanone is more fruity & cheesy. This methyl ketone is a flavor component of blue cheese. 2,3-diethyl-5- methylpyrazine has a burnt, musky, nutty, roast, vegetable and somewhat earthy smell. colorless unsaturated aldehyde. The odor is perceived as orris (iris, tenaciously flowery, heavy and woody, used in spices and for home-made toothpastes.), fat and cucumber and is associated with aged beer and buckwheat, old books, and old people smell. It's production is increased with aging, and is generated by the oxidative degradation of omega-7 generated by the oxidative degradation of omega-7 unsaturated fatty acids, such as palmitoleic acidand vaccenic acid, found on the skin surface. |
