What are the proteins that are present in your body?

Answer 1

Proteins are the body building biomacromolecule seen in the body. Proteins are biopolymers of the basic twenty aminoacids through peptide bonds. Proteins have different levels of structure - Primary, secondary, tertiary (single peptide protein) and quarternary structure (Subunit proteins). Proteins are either globular or fibrillar in nature. Proteins can be classified based on the conjugation and function as follows: * Receptor protein - Photoreceptor Rhodopsin * Nucleoprotein - Histones * Metalloprotein - Haemoglobin, myoglobin - respiratory pigments * skeletal and muskular proteins - actin, myosin, dystrophin * Membrane protein - seen in lipoprotein membrane, RBCs as antigens * Facilitating proteins - Chaperones or heat shock proteins * Structural proteins - keratin, collagen * Immunoproteins - immunoglobulins * Enzymes and hormones - trypsin, insulin
