Write down the structural formula of the tripeptide formed by alanine, glycine, and serine joined together in that order?

Hint: The monomer unit of the protein is known as amino acids and the bond between two amino acids is known as peptide bond and a long chain of the amino acids is known as protein. A chain of three amino acids is known as tripeptide here alanine, glycine and the serine are the amino acids.

Complete answer: 1. Glycine: In glycine amino acid its side chain consists of only one hydrogen atom bonded with it. In all the known amino acid it is the simplest stable amino acid and it is proteinogenic in nature
2. It is very useful to protect the kidney from the harmful effects of the drugs which are used at the time of organ transplantation.
3. It’s chemical formula is ${NH_2}- {CH_2}-COOH$.
4. Serine: serine is a type of alpha-amino acid it has an alpha-amino acid with a Carboxyl group and the hydroxyl methyl group is attached as a side chain. Its chemical formula is ${C_3}{H_7}{NO_3}$.
5. It is an essential amino acid which is used in the formation of phosphatidylserine which is an important component of brain cell.
6. Alanine: Alanine is also an alpha-amino acid which an important aid in the biosynthesis of protein. Its chemical formula is ${C_3}{H_7}{NO_2}$.

Note: Alanine amino acid is used to break vitamin B and tryptophan and strengthen the immune system. It provides nutrition to the Central nervous system and the muscle cells.
