BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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-2: -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-3: -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.

Detailed explanation-4: -Proteins are linear polymers of amino acids connected by peptide bonds. They are synthesized from the template strand of DNA and contain unique and specific amino acid sequences in a linear form known as a primary structure.

Detailed explanation-5: -The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
