Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3 (in which the bond angle between the nitrogen and hydrogen is 107°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...
2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (also known as PhIP) is one of the most abundant heterocyclic amines (HCAs) found in cooked meat. PhIP is formed at high temperatures from the reaction between creatine or creatinine (found in muscle meats), amino acids, and sugar. PhIP formation increases with the temperature and duration of ...
The formation process is inhibited when amine concentration is low (e.g. a low-protein diet or no fermented food). The process may also be inhibited in the case of high vitamin C (ascorbic acid) or erythorbic acid [ 26 ] concentration (e.g. high-fruit diet).
The compounds found in food are formed when creatine (a non-protein amino acid found in muscle tissue), other amino acids and monosaccharides are heated together at high temperatures (125-300 °C or 275-572 °F) or cooked for long periods. HCAs form at the lower end of this range when the cooking time is long; at the higher end of the range ...
Serotonin, an endogenous amine, is a neurotransmitter derived from the amino acid tryptophan. Serotonin is involved in regulating mood, sleep, appetite, and sexuality. [9] The amines are transmitted locally or via the blood system. The exogenous amines are directly absorbed from food in the intestine. Alcohol can increase the absorption rate.
Alkyl dimethyl amine oxide (chain lengths C10–C16) is the most commercially used amine oxide. [3] They are considered a high production volume class of compounds in more than one member country of the Organisation for Economic Co-operation and Development ( OECD ); with annual production over 26,000, 16,000 and 6,800 tonnes (28,700, 17,600 ...
Parasites. Raw and undercooked seafood can also be contaminated with anisakid nematodes, a type of worm that can cause a disease called anisakiasis. CNN reported about the illness and a study that ...
Fatty amines are commonly prepared from fatty acids; which are themselves obtained from natural sources, typically seed-oils.The overall reaction is sometimes referred to as the Nitrile Process [3] and begins with a reaction between the fatty acid and ammonia at high temperature (>250 °C) and in the presence of a metal oxide catalyst (e.g., alumina or zinc oxide) to give the fatty nitrile.
