    Protein Structure | Introduction to Chemistry

    Protein structure plays a key role in its function; if a protein loses its shape at any structural level, it may no longer be functional. Primary structure is the amino acid sequence. Secondary structure is local interactions between stretches of a polypeptide chain and includes α-helix and β-pleated sheet structures.

    Protein Biological Activity: R&D Systems

    The biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. Due to a protein's ability to exert multiple biological activities, several acceptable bioassays may exist for a particular protein and several different cell types may respond.
