What are globular proteins another important function of globular proteins is to act as biological transport a sort of scaffold within the cytoplasm that allows the cell to maintain its shape and structure globular proteins called structure motifs are also found within the cell. Home biology biological molecules biological molecules protein structure protein structure primary structure proteins are made up of polypeptide chains, which are amino acids joined together with peptide bonds its function is to carry oxygen around in the blood. Overview of the protein structure proteins are macromolecules and have four different levels of structure - primary, secondary often, post-translational modifications, such as glycosylation or phosphorylation, occur which are necessary for the biological function of the protein. Enzymes are also proteins what are enzymes enzymes are biological catalysts we say the enzyme has been denatured denatured: if a protein is denatured, its structure and function is altered this can be caused by heat, altered ph or by chemical agents.
