Hey mate here is your answer》》
(1) Membrane Proteins:
Proteins and lipids form the major structural components of cell membrane. The membrane associated proteins consists of intrinsic proteins and extrinsic proteins. Many enzymes and enzyme systems are associated with membrane proteins i.e. components of electron transport system.
(2) Enzymes:
Enzymes are proteins produced within an organism which are capable of catalyzing specific catalytic reactions. They are biocatalysts which influence the rate f a chemical reaction, usually without undergoing any change themselves.
(3) Hormones:
Several hormones are peptides and proteins. They play an important role in the regulation of metabolic reactions.
(4) Blood proteins:
The blood proteins include plasma proteins and haemoglobin.
(a) Plasma proteins are mainly albumin, globulins and fibrinogen. Albumin maintains the colloid osmotic pressure of plasma and transport materials. Globulins inhibit proteolytic enzymes, and helps to immunosystem of the body. Fibrinogen helps in blood clotting. Lipoproteins are concerned with transport of fat in blood.
(b) Haemoglobin is a conjugated protein consisting ofglobin and haeme. Haemoglobin carries oxygen in the form of oxyhaemoglobin in blood.
(5) Antibodies: Some antibodies like gramicidin S, tyrocidin and penicillin G are peptides.
(6) Nucleoproteins: These are conjugated proteins of cell nuclei.
(7) Multiple protein Assemblies: These contain several compounds which together from a functional unit.
(a) Collagen: A fibrous proteins found in many connective tissue.
(b) Flagella: Microtubules of flagella are made up of tubules.
(c) Actionmyosm complex of muscle: Muscle fibres consists of thin filaments of action, tropomyosin and troponin which make up the 1 or light bands and thick filaments of myosin which make up the A or dark bands.

biological significance of proteins proteins are of great importance to the living organisms as they play a certain role in determining their structure and functions
1) structural proteins several proteins as building material of cells and are called structural proteins they play a major role in growth and repair the determine the structure of cell membrane are ribosomes, mitochondria, plastids, microfilaments and etccc some of the proteins from extracellular supporting structures such as collagen and elastin of connective tissues alpha-keratin in Skin ,Hair, feather and etccc The structures for protective covering the cocoon of silkworm is composed of silk fibres of white and insoluble protein called fibroin.
2) functional proteins proteins are workhorses of the cell they perform a variety of functions the following are the major types of functional proteins
3). enzymes these are biocatalyst regulating the metabolism example : RUBISCO , glutamine synthetase, amylase and etccc
4) harmones : several harmones are protenecious
eg: insulin and glucagon for regulating of glucose metabolism and growth harmone for the growth of the body .harmones are chemical messengers for coordinating the functions of the body
5) transport proteins : the proteins also function ascaris or Transporters
eg: hemoglobin transports oxygen in the blood of vertibrates
6) protective proteins : some of the protein protect the body in various ways
eg: antibodies defend the body against the invasions and etccc
7) contractile proteins : the contractile proteins such as myosin and actin present in the muscles of animals bring about the movement
8) storage proteins: the storage proteins are usually globular proteins ( spherical in shape )
eg: egg albumin ,serum albumin,serum globulins milk protein ( casein) and etcccc
9) as buffers : proteins also help in maintenance of pH and regulation of volume of body fluids
10) receptors. proteins: q number of protein of plasma membrane act as receptors of molecules to bind with harmones
11) some protein act as biological buffer and form visual pigments like iodopsin and rhodopsin
12) some protein act as repressor protein to regulate gene actions
some act as toxins
eg: bacterial toxins and ricin
