Biological roles: 1. Amino acids can be metabolized to produce energy. This is especially. important during fasting, when the breakdown of muscle protein is a major. source of energy and biosynthetic precursors. 2. Some amino acids act as neurotransmitters, and some act as starting.
Without protein our body cannot function properly. Our body nerves, tissues, bones all are made up of proteins. So proteins become very necessary for them to grow and repair. It also used to produce some hormones and enzymes in our body .proteins are made up of amino acids.Our body produces non essential amino acids and also requires the essential amino acids which we take from the food.Amino acids are present in the proteins. It has been proved by the physicists that nearly 98% of our body atoms get replaced in a year.ur body produces non essential amino acids and also requires the essential amino acids which we take from the food.
