BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Secondary structure is the next level up from the primary structure, and is the regular folding of regions into specific structural patterns within one polypeptide chain. Hydrogen bonds between the carbonyl oxygen and the peptide bond amide hydrogen are normally held together by secondary structures.

Detailed explanation-2: -The secondary structure arises from the hydrogen bonds formed between atoms of the polypeptide backbone. The hydrogen bonds form between the partially negative oxygen atom and the partially positive nitrogen atom.

Detailed explanation-3: -Secondary structure refers to regular, recurring arrangements in space of adjacent amino acid residues in a polypeptide chain. It is maintained by hydrogen bonds between amide hydrogens and carbonyl oxygens of the peptide backbone. The major secondary structures are -helices and -structures.

Detailed explanation-4: -Secondary structure The most common types of secondary structures are the helix and the pleated sheet. Both structures are held in shape by hydrogen bonds, which form between the carbonyl O of one amino acid and the amino H of another.

Detailed explanation-5: -Secondary Structure (2˚)–Alpha Helices. While primary structure describes the sequence of amino acids forming a peptide chain, secondary structure refers to the local arrangement of the chain in space. Several common secondary structures have been identified in proteins.
