PATHOLOGY

Detailed explanation-1: -Answer and Explanation: The polypeptides with over 100 amino acids long chain are known as Proteins. Proteins are large molecules or macromolecules that are composed of long chains of polypeptides.

Detailed explanation-2: -Proteins are macromolecular polypeptides-i.e., very large molecules (macromolecules) composed of many peptide-bonded amino acids. Most of the common ones contain more than 100 amino acids linked to each other in a long peptide chain.

Detailed explanation-3: -Peptides containing more than 10 amino acids are called poly peptides.

Detailed explanation-4: -A peptide is a short string of 2 to 50 amino acids, formed by a condensation reaction, joining together through a covalent bond.
