Is it not one of the strands or components of DNA? I may have to use Google too.
谁能解释一下？我好害怕好困惑。

Glycine (symbol Gly or G;[6] /ˈɡlaɪsiːn/ ⓘ)[7] is an amino acid that has a single hydrogen atom as its side chain. It is the simplest stable amino acid (carbamic acid is unstable). In the gas phase, it is a molecule with the chemical formula NH2‐CH2‐COOH. In solution or in the solid, glycine exists as the zwitterion. Glycine is one of the proteinogenic amino acids. It is encoded by all the codons starting with GG (GGU, GGC, GGA, GGG). Glycine is integral to the formation of alpha-helices in secondary protein structure due to the "flexibility" caused by such a small R group. Glycine is also an inhibitory neurotransmitter – interference with its release within the spinal cord (such as during a Clostridium tetani infection) can cause spastic paralysis due to uninhibited muscle contraction.
