BIOMOLECULES AND ENZYMES

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. Therefore, they are known as macromolecular polypeptides.

Detailed explanation-2: -Polypeptides containing more than 100 amino acids having molecular mass higher than 10, 000 are generally called as proteins.

Detailed explanation-3: -Conversely, chains of approximately 100 amino acids or more are termed proteins 1. Glycoproteins are proteins with a carbohydrate component and lipoproteins are proteins with a lipid component. The sequence of amino acids in the protein chain is called the primary structure.

Detailed explanation-4: -Proteins are large molecules made from smaller building blocks called amino acids. If there are less than 10 amino acids the molecule is called a peptide; if 10 to 100 a polypeptide; and more than 100 a ‘protein.

Detailed explanation-5: -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.
