Major functions of proteins are enzyme, receptor and immunological antibody. Enzyme is the most important in them because metabolic system of cell is chemical reactions catalyzed by network of enzymes. Protein kinase and phosphatase is important system to regulate enzyme activity as well as allosteric...

Proteins are highly complex substances present in all living organisms that are of great nutritional value and that are directly involved in the chemical processes essential for life.
Proteins are made up of long chains of amino acids, just a chain of ami. tacids makes up the primary structure. The secondary structure is formed by hydrogen bonds joining the chains in certain places to make an alpha helix or a beta sheet. The tertiar..

Within cells, as well as outside, proteins serve a myriad of functions. The chief characteristic of proteins that allows their diverse set of functions is their ability to bind other molecules (proteins or small-molecule substrates) specifically and tightly....
