BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The linear sequence of amino acids within a protein is considered the primary structure of the protein. Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries. The largest group of amino acids have nonpolar side chains.

Detailed explanation-2: -Primary structure refers to the linear sequence of the amino acids connected by the peptide bonds. The secondary structure consists of local packing of polypeptide chain into -helices and -sheets due to hydrogen bonds between peptide bond – central carbon backbone.

Detailed explanation-3: -Primary Structure (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-4: -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-5: -The primary structure of a protein necessarily linear (rather than branched) sequence of amino acids because it is able to coil and fold upon itself, resulting in 3D formations such as alpha helices and beta sheets.
