BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The primary structure of a peptide or protein is the linear sequence of its amino acids (AAs). By convention, the primary structure of a protein is read and written from the amino-terminal (N) to the carboxyl-terminal (C) end. Each amino acid is connected to the next by a peptide bond.

Detailed explanation-2: -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-3: -The primary structure is comprised of a linear chain of amino acids. The secondary structure contains regions of amino acid chains that are stabilized by hydrogen bonds from the polypeptide backbone. These hydrogen bonds create alpha-helix and beta-pleated sheets of the secondary structure.

Detailed explanation-4: -The actual order of the amino acids in the protein is called its primary structure and is determined by DNA. The order of deoxyribonucleotide bases in a gene determines the amino acid sequence of a particular protein.

Detailed explanation-5: -Primary structure refers to the amino acid order of a simple peptide chain. Secondary structures – commonly alpha-helix, beta-strand, or beta-sheet – create spirals, coils, or sheet forms from a single polypeptide chain by way of hydrogen bonds.
