BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Primary structure. The simplest level of protein structure, primary structure, is simply the sequence of amino acids in a polypeptide chain.

Detailed explanation-2: -A peptide bond forms when the amino group of one amino acid bonds to the carboxyl group of another amino acid. The actual order of the amino acids in the protein is called its primary structure (Figure 19.1.

Detailed explanation-3: -The linking of two amino acids entails the release of a water molecule. Hence, the process that links two amino acids together is called condensation. The condensation reaction is also called a dehydration reaction.
