Why We Need Proteins

by Angela Royston

Protein is essential to all life. Our organs, bones, muscles, skin, and hair either contain or are made of proteins. This engaging title explains how our bodies break down large protein molecules into the amino acids that our bodies need to maintain our muscles, bones, blood, and body organs. Readers will also discover the differences between structural and functional proteins and complete and incomplete proteins.
