Proteins are among the most abundant organic molecules in living systems and are vastly diverse in structure and function as compared to other classes of macromolecules. Even one cell contains thousands … See more

Four different structures of protein serve to influence specific protein activities. Different sequences of amino acids form different shapes and thus, different proteins. All protein activity is based on these four structures: … See more

The term protein denotes molecules with >50 combined amino acids. Each protein contains one or more polypeptide chain. The chemical properties and order of the amino acids determines the structure and function of t… See more

The amino acids' interactions cause a protein to fold into its mature shape (tertiary). Such folding happens because of the rotation of bonds within the amino acids, as well as bonds joining various amino acid… See more

Protein denaturation occurs when the three-dimensional structures (in secondary, tertiary, or sometimes quaternary structures) of proteins is altered. Denaturation makes protein non-functional, or at least … See more
