The original betaine, N,N,N-trimethylglycine, was named after its discovery in sugar beet (Beta vulgaris subsp. vulgaris) in the nineteenth century. [4] It is a small N-trimethylated amino acid. It is a zwitterion, which cannot isomerize because there is no labile hydrogen atom attached to the nitrogen atom.
Trimethylglycine is an amino acid derivative with the formula (CH 3) 3 N + CH 2 CO − 2.A colorless, water-soluble solid, it occurs in plants. [5] Trimethylglycine is a zwitterion: the molecule contains both a quaternary ammonium group and a carboxylate group.
Codon–amino acids mappings may be the biological information system at the primordial origin of life on Earth. [122] While amino acids and consequently simple peptides must have formed under different experimentally probed geochemical scenarios, the transition from an abiotic world to the first life forms is to a large extent still unresolved ...
Osmoprotectants can be placed in three chemical classes: betaines and associated molecules, sugars and polyols, and amino acids. These molecules accumulate in cells and balance the osmotic difference between the cell's surroundings and the cytosol . [ 2 ]
Despite the name cocamidopropyl betaine, the molecule is not synthesized from betaine. Instead it is produced in a two-step manner, beginning with the reaction of dimethylaminopropylamine (DMAPA) with fatty acids from coconut or palm kernel oil (lauric acid, or its methyl ester, is the main constituent). The primary amine in DMAPA is more ...
Dimethylaminopropylamine (DMAPA) is a diamine used in the preparation of some surfactants, such as cocamidopropyl betaine which is an ingredient in many personal care products including soaps, shampoos, and cosmetics. BASF, a major producer, claims that DMAPA-derivatives do not sting the eyes and makes a fine-bubble foam, making it appropriate ...
Reduced-Fat Cheddar Cheese. 3.9 ounces reduced fat cheddar cheese: 30 grams of protein
It is an amino acid derivative, naturally produced in the human body from the amino acids glycine and arginine, with an additional requirement for S-adenosyl methionine (a derivative of methionine) to catalyze the transformation of guanidinoacetate to creatine.
