Define Body Building functions of proteins?
The primary functions of proteins, as you might be aware, is tissue growth and maintenance. Protein contains amino acids - the building blocks - hat our bodies use to build and maintain muscles, bone, skin, blood and other organs. Thus, proteins play an important role in growth and body-building. For the constant growth of human beings from birth to adulthood, a regular supply of dietary protein is required. Now this does not mean that the body does not require proteins once the growth ceases. During adulthood, worn out cells, body tissues need continuous replacement. Proteins are required for maintenance of our body. Proteins, therefore, are crucial and required throughout our life span for growth, body-building and maintenance.
