BIOMOLECULES AND ENZYMES

Detailed explanation-1: -A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule; thereby, releasing a molecule of H2O. This is a dehydration synthesis reaction and usually occurs between amino acids and the resulting molecules is an amide.

Detailed explanation-2: -Amino acids are attached to other amino acids by covalent bonds, known as peptide bonds, which are formed by dehydration synthesis reactions.

Detailed explanation-3: -Peptide bonds form between the carboxyl group of one amino acid and the amino group of another through dehydration synthesis. A chain of amino acids is a polypeptide.

Detailed explanation-4: -A peptide bond, also referred to as an amide bond, is formed between the -nitrogen atom of one amino acid and the carbonyl carbon of a second (diagrammed below).

Detailed explanation-5: -Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid. The linear sequence of amino acids within a protein is considered the primary structure of the protein.
