BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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.

Detailed explanation-2: -In the polypeptide chain, the main structure of a protein relates to the amino acid sequence. The primary structure is bound together by peptide bonds that are made during the phase of protein biosynthesis.

Detailed explanation-3: -Primary Structure Peptide bonds are amide bonds between the -carboxyl group of one amino acid and the -amino group of another (Fig. 3-1). The result is a planar structure that is stabilized by resonance between the -carboxyl and -amino groups.

Detailed explanation-4: -The primary structure is held together by covalent peptide bonds. They are formed during the process of protein biosynthesis, where the amino acids lose one water molecule per reaction to attach to another amino acid. The secondary structure is determined by hydrogen bonds between the main-chain peptide groups.

Detailed explanation-5: -To reiterate, the primary structure of a protein is defined as the sequence of amino acids linked together to form a polypeptide chain. Each amino acid is linked to the next amino acid through peptide bonds created during the protein biosynthesis process.
