Four structures of proteins
WebNov 27, 2024 · Proteins are macromolecules and have four different levels of structure – primary, secondary, tertiary and quaternary. Primary Structure There are 20 different standard L-α-amino acids used by cells for protein construction. Amino acids, as their name indicates, contain both a basic amino group and an acidic carboxyl group. WebProtein structure is organized at four levels: primary, secondary, tertiary, and quaternary. The primary structure is the unique sequence of amino acids. A change in just one amino acid can change protein structure and function. For example, sickle cell anemia results from just one amino acid substitution in a hemoglobin molecule consisting of ...
