BIOMOLECULES AND ENZYMES

Detailed explanation-1: -In a polypeptide chain, a peptide has two residues, the first is the N-terminus and the second is the C-terminus. When a Carboxyl group (-COOH) of amino acid is bound with another amino group of amino acid, then a peptide chain is formed. The amino group and Carboxyl group (-COOH) are attached alpha-carbon atoms.

Detailed explanation-2: -The C-terminus (also known as the carboxyl-terminus, carboxy-terminus, C-terminal tail, C-terminal end, or COOH-terminus) is the end of an amino acid chain (protein or polypeptide), terminated by a free carboxyl group (-COOH).

Detailed explanation-3: -Additional amino acids can be added on through the formation of addition peptide (amide) bonds. A sequence of amino acids in a peptide or protein is written with the N-terminal amino acid first and the C-terminal amino acid at the end (writing left to right).

Detailed explanation-4: -Amino Acids, Peptides, and Proteins During translation, peptide bonds are formed from the amino (N) to the carboxyl (C) terminus by removal of water (also referred to as dehydration or condensation) and catalyzed by RNA (referred to as a ribozyme) that forms part of the ribosome.
