Alanine (symbol Ala or A), [4] or α-alanine, is an α-amino acid that is used in the biosynthesis of proteins. It contains an amine group and a carboxylic acid group, both attached to the central carbon atom which also carries a methyl group side chain. Consequently it is classified as a nonpolar, aliphatic α-amino acid.
Chemical formula: C 3 H 7 N O 2 Molar mass: 89.1 g·mol −1 Systematic name: (S)-2-aminopropanoic acid Abbreviations: A, Ala Synonyms: 2-aminopropanoic acid {α/2}-aminopropionic acid AIDS{-}071780 HSDB 1801 NSC 206315
Alaninol is the organic compound with the formula CH 3 CH(NH 2)CH 2 OH. A colorless solid, the compound is classified as an amino alcohol.It can be generated by converting the carboxylic group of alanine to an alcohol with a strong reducing agent such as lithium aluminium hydride. [1]
The liver transaminases aspartate transaminase (AST or SGOT) and alanine transaminase (ALT or SGPT) are useful biomarkers of liver injury in a patient with some degree of intact liver function. [2] [3] [4] Most liver diseases cause only mild symptoms initially, but these diseases must be detected early. Hepatic (liver) involvement in some ...
This enzyme is also called L-alanine racemase. This enzyme participates in alanine and aspartate metabolism and D-alanine metabolism. It employs one cofactor, pyridoxal phosphate. At least two compounds, 3-Fluoro-D-alanine and D-Cycloserine are known to inhibit this enzyme. The D-alanine produced by alanine racemase is used for peptidoglycan ...
Alanine dehydrogenase (EC 1.4.1.1) is an enzyme that catalyzes the chemical reaction. L-alanine + H 2 O + NAD + pyruvate + NH 3 + NADH + H +. The 2 substrates of this enzyme are L-alanine, water, and nicotinamide adenine dinucleotide + because water is 55M and does not change, whereas its 4 products are pyruvate, ammonia, NADH, and hydrogen ion.
β-Alanine is the rate-limiting precursor of carnosine, which is to say carnosine levels are limited by the amount of available β-alanine, not histidine. [6] Supplementation with β-alanine has been shown to increase the concentration of carnosine in muscles, decrease fatigue in athletes, and increase total muscular work done.
In enzymology, a beta-alanine-pyruvate transaminase (EC 2.6.1.18) is an enzyme that catalyzes the chemical reaction. L-alanine + 3-oxopropanoate pyruvate + beta-alanine. Thus, the two substrates of this enzyme are L-alanine and 3-oxopropanoate, whereas its two products are pyruvate and beta-alanine.
