functions of proteins in living systems

Proteins are complex compounds made up of chains of nitrogen containing building blocks called amino acids. Besides nitrogen they also contain carbon, hydrogen and oxygen. The proteins present in living organisms contain more than 20 amino acids and each of them have ..

Metals in the Living System - Traces of metal is necessary for the human and animal system to function efficiently. Some of the important metals required are iron, copper, zinc, sodium and potassium. Iron metal is a constituent of haemoglobin in blood which c..

. The enzyme ribonuclease and the protein myoglobin function only in their primary structure. If the polypeptide chain is coiled into a spiral or helix to have a three-dimensional structure, then it is called secondary structure. e.g., keratin of ski..

Proteins perform essential and specialized functions in living cells. Proteins are primarily responsible for the structure and strength of the body. Some proteins act as enzymes, hormones, blood clotting factors, etc. These are the dynamic func..

1) Proteins build new tissues of the body. 2) They maintain and replace damaged tissues. 3) They carry out regulating activities as enzymes and hormones. 4) They are protective as antibodies. 5) They help in other important activities such as movement of skeletal muscles, transport of ox..

Organisation refers to a kind of structure or system or situation where the smaller components become arranged into larger ones in a hierarchical order of complexity, to co-ordinate with one another in performing common functions or achieving common goals. In the living..

Proteins - Introduction - Proteins are the high molecular mass complex biopolymers of amino acids and organic compounds that are most important to life. They are essential for growth and maintenance of life. They are high molecular weight, nitrogen rich substances that are prese..

Denaturation of Proteins - Proteins found in a biological system with definite configuration and biological acts is called a native protein. Denaturation is a process by which the native form of protein structure is disorganized. This causes drastic..
