In chemistry, an amino acid is a molecule that contains both amine and carboxyl functional groups. In biochemistry, this term refers to alpha-amino acids with the general formula H2NCHRCOOH, where ...

Leucine and isoleucine are among the 20 amino acids found naturally in the human body. They are very similar in structure but have small differences which change their physiological properties.

All living organisms encode the amino acid sequences of proteins as nucleotide sequences (genetic information) in their ...

Amino acids possess distinct pK a s for the carbonyl group, amino group, and any functional groups on the side chain that may be protonated or deprotonated. There is always one more structure than ...

Researchers report that carboxylic acids, functional groups contained in biomolecules, drugs, and materials can be readily modified by light-induced organic reactions using an aminocyclopropenone.

In a recent article published in Scientific Reports, researchers explored the synthesis and characterization of amino acid-functionalized magnetite nanoparticles (Fe₃O₄@AA) and their potential ...

Functional amino acids play a critical role in the development of both animals and humans, according to a Texas AgriLife Research scientist. In a journal article appearing in the American Society ...
