Detailed explanation-1: -Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.

Detailed explanation-2: -Arbitrarily proteins are categorized according to length of the amino acid chain: if less than one hundred amino acids, then they are peptides, subdivided into oligopeptides (2-10 amino acids) and polypeptides (11-99 amino acids). Conversely, chains of approximately 100 amino acids or more are termed proteins 1.

Detailed explanation-3: -When connected together by a series of peptide bonds, amino acids form a polypeptide, another word for protein.

Detailed explanation-4: -The proteins with the smaller units of molecules or monomers called amino acids. Amino acids are organic molecules, which have two ends named amino and carboxyl terminal ends. There are 21 amino acids, which are called monomers.

Detailed explanation-5: -True. Proteins are composed of amino acids. The amino acids that comprise proteins are connected via peptide linkages. They are composed of a linear chain folded into a globular structure.
