Question

Weightlifters are often concerned with the amount of protein in their diets because growing muscles require protein. Just as muscles need the basic building block of protein, protein itself also has basic building blocks. Which of the following are the building blocks of protein?

Answer 1

Amino acid is the basic building block of proteins; when linked together, amino acids form specific proteins. There are more than 50 known amino acids, but only 20 are used in making proteins and only 9 are considered essential.
