Document Summary

Q proteins are large, complex molecules found in the cells of all living things. Best known as a part of our muscle mass. Functions in metabolism, immunity, fluid balance, and nutrient transport. Also, it can provide energy in certain circumstances. Q proteins are one of the three macronutrients. Q found in a wide variety of foods. Q are made according to instructions provided by our genetic material, or dna. Q another difference between proteins and other macronutrients lies in their chemical makeup. Contains carbon, hydrogen, oxygen, and nitrogen special form of nitrogen that our body can readily use. The building blocks of protein are amino acids. Q the proteins in our bodies are made from a combination of building blocks called amino acids. The portion of the amino acid that makes each unique is its side chain. Variations in the structure of the side chain give each amino acid its distinct properties.
