Biochemistry: The Importance Of Proteins

Proteins are the most abundant molecules in cells, making up 50% or more of their dry weight. Every protein has unique structure and conformation or shape, which enables it to carry out a specific function in a living cell. Proteins comprise the complex muscle system and the connective tissue network, and they are important as carriers in the blood system. All enzymes are proteins, enzymes

All proteins contain carbon, hydrogen, nitrogen and oxygen. Most protein contain sulfur and some additional element. For example, milk proteins contain phosphorus and hemoglobin and myoglobin contain iron. Copper and zinc also are constituents of some protein.

Protein is one of the most important element for the maintenance of good health. Protein is needed for the growth, formation and repair of body cells. It forms part of the structure of every cell in your body, including muscle, skin, hair and nails. All the tissues, bones and brain. One of the important protein, collagen helps make scar tissue, forms the protein base of teeth, along with the material of ligaments and tendons and is a strengthening part of arterial walls. It is also needed for making enzymes, hormones and antibodies. Your bodies cannot store protein, so it must be supplied on a daily basis from the foods you eat.

They play an important role in determining the texture of a food. There are two type of food of protein which is animal protein and vegetable protein. Animal protein sources such as poultry, fish, meat, dairy products and egg generally provide higher concentration of protein than vegetables sources such as beans, lentils, nuts, grains, soya and
