How amino acids keep your body running: From muscle repair to blood cells

Proteins in our cells do the key work of sustaining and growing organs. And those proteins are built from more than 20 amino acids — the body’s basic building blocks.

Scientists say the specific sequence of these amino acid chains determines the structure and function of each protein in the cells.Several amino acids play specialized roles.

Glycine, for example, is vital for the formation of blood cells. Leucine, an essential amino acid, is involved in muscle growth, tissue repair, and energy production.

The body cannot make all of them on its own. There are nine essential amino acids in total that must come from food to keep organs functioning. The other eight, along with leucine, need to be supplied externally through diet.

Experts note that without a regular supply of these essential amino acids, the body cannot produce the proteins needed for growth, repair, and day-to-day cellular functions.
