Protein

Functions

Repair and Maintenance


Protein is termed the building block of the body. It is called this because protein is vital in the maintenance of body tissue, including development and repair. Hair, skin, eyes, muscles and organs are all made from protein. This is why children need more protein per pound of body weight than adults; they are growing and developing new protein tissue.


Energy


Protein is a major source of energy. If you consume more protein than you need for body tissue maintenance and other necessary functions, your body will use it for energy. If it is not needed due to sufficient intake of other energy sources such as carbohydrates, the protein will be used to create fat and becomes part of fat cells.

Reasoning

Proteins are made up of amino acids, the building blocks, linked together. A typical protein may contain 300 or more amino acids. Each protein has its own specific number and sequence of amino acids. The shape of the molecule is important as it often determines the function of the protein. There are about twenty different amino acids commonly found in plants and animals. Every cell in the human body
contains protein as part of its structure (cell membrane and other
structures). It also serves to build strong structures in the body, as a
whole it makes up the compounds that your body used to make the biochemical reactions occur in your body
