BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Proteins are polymers of smaller subunits called amino acids. The continuous chains of amino acids form peptide chains and then multiple peptide chains club together to form a protein molecule. The length of repeated units of amino acids in a peptide chain varies from 18-47.

Detailed explanation-2: -The repeating units of proteins are called fatty acids.

Detailed explanation-3: -A repeat unit is sometimes called a mer (or mer unit). “Mer” originates from the Greek word meros, which means “a part". The word polymer derives its meaning from this, which means “many mers".

Detailed explanation-4: -An amino acid unit in a polypeptide chain is written by starting with amino terminal residue and ending with-COOH terminal. One is basic and the other is acidic and these two are the only ionizable groups of the peptide chain except those present in side chain.

Detailed explanation-5: -Amino acid repeats (AARs) are segments of proteins made up of simple patterns of amino acids, often strings of a single amino acid. They have long been recognized to be common features of eukaryotic proteins [1–4].
