The Chemistry of Food, Part 3--Proteins and Amino Acids

this is a very interesting article, it shows how proteins are an important class of macronutrients. Our bodies use proteins for growth and to build and repair body tissues. Each protein is a large complex molecule made up of a long chain of building blocks called amino acids. when we eat food, the digestive enzymes break the protein down into shorter amino acids chain and to individual amino acids. the amino acids then enter the blood stream and travel to the cells where they are incorporated into new proteins. if you want to know more, visit the website http://www.suite101.com/article.cfm/chemistry/78267
