Glycine is a non-essential amino acid and has the simplest structure of all amino acids, allowing it to fit easily within protein chains and make space for structurally larger amino acids. &ampnbsp;This feature makes it very important for specific bodily functions. &ampnbsp;Glycine is also a precursor of creatine, which is used to construct DNA and RNA. &ampnbsp;And it supports glycogen storage, thereby making more glucose available for energy production.* &ampnbsp;The amino acid Glycine is non-chiral and only has one form without a D- or L- designation.
