What is protein and its type?

Proteins are biological polymers composed of amino acids. Amino acids, linked together by peptide bonds, form a polypeptide chain. One or more polypeptide chains twisted into a 3-D shape form a protein. … There are two general classes of protein molecules: globular proteins and fibrous proteins.

What is the smallest protein in your body?

The smallest human protein is 44 amino acids but it could be an abortive translation from the 5′ UTR of another mRNA. The smallest functional polypeptide is glutathione with only three amino acids. BTW, proline is technically not even an amino acid much less a polypeptide.
