BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Hydrogen bonding between amino groups and carboxyl groups in neighboring regions of the protein chain sometimes causes certain patterns of folding to occur. Known as alpha helices and beta sheets, these stable folding patterns make up the secondary structure of a protein.

Detailed explanation-2: -There are three common secondary structures in proteins, namely alpha helices, beta sheets, and turns.

Detailed explanation-3: -The complete structure of a protein can be described at four different levels of complexity: primary, secondary, tertiary, and quaternary structure.

Detailed explanation-4: -The three secondary structure elements are the alpha helix, the beta-sheet, and the turn.

Detailed explanation-5: -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.
