Question

Why are protiens and minerals required in small quantities only?

Answer 1

Proteins are not needed in small quantities. The nutrients which are required in small quantities are vitamins and minerals. It is because vitamins and minerals are protective in functions and play a role in protecting our body from diseases and infections. But proteins play a role in building up of muscles, maintenance and repair of other body cells. So they are needed in large quantity for proper growth of the body.
