β-Alanine (beta-alanine) is a naturally occurring beta amino acid, which is an amino acid in which the amino group is attached to the β-carbon (i.e. the carbon two carbon atoms away from the carboxylate group) instead of the more usual α-carbon for alanine (α-alanine). The IUPAC name for β-alanine is 3-aminopropanoic acid.
“Among the top food sources of carnosine (and thus beta-alanine) are animal products, including beef, chicken (and chicken broth), and fish (with the highest levels of BA found in mackerel, tuna ...
A rare exception to the dominance of α-amino acids in biology is the β-amino acid beta alanine (3-aminopropanoic acid), which is used in plants and microorganisms in the synthesis of pantothenic acid (vitamin B 5), a component of coenzyme A. [77]
The methyl side-chain of alanine is non-reactive and is therefore hardly ever directly involved in protein function. [12] Alanine is a nonessential amino acid, meaning it can be manufactured by the human body, and does not need to be obtained through the diet. Alanine is found in a wide variety of foods, but is particularly concentrated in meats.
Dietary fibre from fruits, vegetables and grain foods. Insoluble dietary fibre is not absorbed in the human digestive tract but is important in maintaining the bulk of a bowel movement to avoid constipation. [5] Soluble fibre can be metabolized by bacteria residing in the large intestine.
The Food and Nutrition Board (FNB) of the U.S. Institute of Medicine set Recommended Dietary Allowances (RDAs) for essential amino acids in 2002. For leucine, for adults 19 years and older, 42 mg/kg body weight/day; for isoleucine 19 mg/kg body weight/day; for valine 24 mg/kg body weight/day. [6]
β-alanine, an example of a β-amino acid. The amino group attaches not to the α carbon but to the β-carbon, which in this case is a methylene group.. Beta-peptides (β-peptides) are peptides derived from β-amino acids, in which the amino group is attached to the β-carbon (i.e. the carbon two atoms away from the carboxylate group).
