BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Because amino acid sequence determines protein structure and structure dictates biochemical function, proteins that share a similar amino acid sequence usually perform similar biochemical functions, even when they are found in distantly related organisms.

Detailed explanation-2: -The primary structure of a protein-its amino acid sequence-drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein’s unique three-dimensional shape.

Detailed explanation-3: -Proteins fold up into specific shapes according to the sequence of amino acids in the polymer, and the protein function is directly related to the resulting 3D structure. Proteins may also interact with each other or other macromolecules in the body to create complex assemblies.

Detailed explanation-4: -The unique amino acid sequence of a protein is reflected in its unique folded structure. This structure, in turn, determines the protein’s function.

Detailed explanation-5: -Every protein has a shape that helps the molecule do its job. Collagen in our cartilage and tendons, for instance, has a three-stranded, rope-like structure that makes it strong. Enzymes-proteins that facilitate chemical reactions-typically have a pocket that holds the molecule they act upon.
