Respuesta :
Glycine is the only amino acid that is not optically active because it does not have a carbon chiral center.
The simplest amino acid is glycine. Because it is the only amino acid without an asymmetrical carbon atom, it differs from all the other amino acids. Glycine is therefore optically inactive. No stereoisomers exist in it. This amino acid is necessary for the manufacture of bile acids, porphyrins, creatine phosphate, and other amino acids as well as nucleic acids.
When compared to the other amino acids, glycine is integrated into proteins and enzymes at a rate of 7.5%, making it the second most prevalent amino acid on a molar basis. Glycine shares a similar ability to block neurotransmitter impulses in the central nervous system with gamma-aminobutyric acid and glutamic acid.
