Carnosine (beta-alanyl-L-histidine) is a dipeptide molecule, made up of the amino acids beta-alanine and histidine. It is highly concentrated in muscle and brain tissues. [citation needed] Carnosine was discovered by Russian chemist Vladimir Gulevich. [1] Carnosine is naturally produced by the body in the liver [2] from beta-alanine and histidine.
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.
”Beta-alanine is an amino acid that is a building block of carnosine, while creatine is a molecule that is made up of three different amino acids (methionine, glycine, and arginine),” says ...
Carnosine synthase (EC 6.3.2.11) is an enzyme that catalyzes the chemical reaction ATP + L-histidine + beta-alanine ⇌ {\displaystyle \rightleftharpoons } ADP + phosphate + carnosine The 3 substrates of this enzyme are ATP , L-histidine , and beta-alanine , whereas its 3 products are ADP (previously thought to form AMP [ 1 ] ), diphosphate ...
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).
Anserine (β-alanyl-3-methylhistidine) is a dipeptide containing β-alanine and 3-methylhistidine. [1] Anserine is a derivative of carnosine, which has been methylated. [2] Both anserine and carnosine chelate copper. [3] Due to its methylation, anserine is more stable in serum and resistant to degradation than carnosine. [4]
