A non-essential amino acid. It is found primarily in gelatin and silk fibroin and used therapeutically as a nutrient. It is also a fast inhibitory neurotransmitter.
A non-essential amino acid, chemically the simplest of the amino acids, it is amino- acetic acid, CH2NFI2COOH.
Glycine is a nonessential amino acid synthesized from serine. Glycine, along with arginine and methionine, is used in the production of creatine, which has been demonstrated in many studies to enhance performance of repeated bouts of high intensity exercise. Due to its role in creatine production, glycine is sometimes touted as an ergogenic aid. To date no studies have supported an ergogenic effect of glycine. Early research by Hilsendager and Karpovich has suggested that enhance short-term muscular endurance.
Non-essential amino acid, widely found in proteins, preparations of which are used in antacids and in the treatment of some muscle disorders.
