Solution
On the basis of synthesis within the body, amino acids are divided into two groups; essential and non-essential amino acids. Glycine belongs to the category of non-essential amino acid because it synthesised within the body and need not to be supplied in the diet. On the contrary essential amino acids are those amino acids which cannot be synthesised within the body and must be supplied with food.
