    Antibody Structure

    Overview
    Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

    Conjugated Proteins

    Simple proteins and protein complexes contain only amino acids. In contrast, many other proteins, called conjugated proteins, covalently bond with non-protein moieties.
    Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...

    What are Proteins?

    Proteins are polymers of amino acids linked together by peptide bonds. Proteins and polypeptides are interchangeably used to refer to long chains of amino acids. However, polypeptides have a molecular weight of fewer than 10,000 daltons, while proteins have greater molecular weight.  Polypeptides with less than 20 amino acids are called oligopeptides or simply peptides. Interactions among the constituent amino acid side chains of proteins help them fold into a stable 3-dimensional structure...

    Role of Proteins in the Human Body

    Proteins are the building block of life. They are also  the most abundant macromolecules with as many diverse roles in the body. They are part of many structural components that provide unique shapes and structures to animal cells, tissues, and organs. In addition, they also act as biological catalysts and carry out several anabolic and catabolic reactions. Notably, some proteins are chemical messengers and regulate many critical processes, such as metabolism, growth, and development. They are...
