Class 5 protein functional classification
14 likes7,794 views
Proteins are organic compounds composed of amino acids linked by peptide bonds. They are classified based on their function in the body. The main classes of proteins include structural, catalytic, contractile, transport, protective, hormonal, immunological, genetic, and nutritive proteins. Structural proteins provide structure to cells and organs, catalytic proteins act as enzymes to speed up metabolic reactions, and transport proteins help move molecules within and between cells.
Class 5 protein functional classification
- 1. Proteins • Organic compounds • Contains C, H,O, N, AND P ,S • Mixed polymer of amino acids • Linked together by peptide bonds N terminal C terminal H2N COOH Polypeptide / Protein n
- 2. Classification of protein Based on function
- 3. Hi ! Genetic Structure Of cat Was Contractile Hence Transported For Protection , but Eaten up (Nutritional)
- 4. Hormonal protein • Some hormones are protein in nature • They regulate metabolic pathways by fine tuning • E.g. Insulin, Glucagon, Growth hormone
- 5. Immuno protein • Immunoglobulins and Antibodies are proteins synthesized against antigen. • They provide immunity and help in defence. • E.g. Immunoglobulins –G,A,M,D,E, Acute phase proteins.
- 6. Genetic protein • Basic proteins, always found in association with Nucleic acid – DNA. • It provide stability to the DNA structure, • E.g. Nucleoproteins (Histones), Repressor proteins, Inducer proteins, SSBP.
- 7. Structural protein • This class of protein provides structural frame work for cell and organs. • E.g. Keratin, Collagen, Actin, Myosin, Elastin, Fibroin,
- 8. Catalytic protein • Also called ENZYMES • Class of protein act as catalyst in metabolic reactions and speed up the reaction rate. • E.g. Amylase, Pepsin, Trypsin, Lipase.
- 9. Contractile protein • Class of protein responsible for movement. • E.g. Actin, Myosin, Tubulin, Flegella, cilia.
- 10. Transport protein • Protein which help in transport of molecules and metabolites inside the cell or across the cell. • E.g. Hemoglobin, Ceruloplasmin, Transferin, Lipoproteins, Albumin, RBP, TBPA,
- 11. Protective protein • Some proteins provide protection. • E.g. Fibrinogen, Prothrombin, • Receptor proteins,
- 12. Nutritive protein • Some proteins provide good nutrition when consumed in proper amount. • E.g: Casein, Albumin, Lactalbumin, Gliadin, Oricin,
