BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The free amine end of the chain is called the “N-terminus” or “amino terminus” and the free carboxylic acid end is called the “C-terminus” or “carboxyl terminus”. The fact that these two protein termini are chemically different form one another means that they will naturally have different chemical properties.

Detailed explanation-2: -The directionality of protein synthesis is dictated by the ribosome and is known as N-to C-synthesis. Figure 2.10 Formation of the Peptide Bond. The addition of two amino acids to form a peptide requires dehydration synthesis.

Detailed explanation-3: -The amino acid that forms the N-terminus of the protein is leucine (leu). It is an essential amino acid used in the synthesis of proteins.

Detailed explanation-4: -The N-terminal amino acid is Serine in the given peptide. It is the amino acid in which free carboxylic acid is present.
