Glycine
Glycine is the simplest of the 20 standard amino acids and is represented by the symbol Gly (G). Its chemical formula is C2H5NO2, with a molecular weight of about 75.07 g/mol. The side chain consists of a single hydrogen atom, making glycine non-chiral and the smallest amino acid. In proteins, glycine is often considered nonpolar, though its small size gives it particular flexibility in protein structures.
Glycine is encoded by the codons GGU, GGC, GGA, and GGG. It is a nonessential amino acid
In the body, glycine serves multiple roles. It functions as an inhibitory neurotransmitter in the spinal cord
Dietarily, glycine is found in protein-rich foods and is also consumed as a dietary supplement. It is
