PY - 2014 T2 - Anesthesiology Core Review: Part One Basic Exam AB - Proteins are biological molecules that serve various functions, including muscle structure and contraction, molecular transportation, enzymatic reactions, and as an energy source. Proteins form three-fourth of the total body solids and are the second most abundant molecule in the body after water. Amino acids are the building blocks of proteins. Amino acids contain an acidic group and a nitrogen-containing amino group. There are 20 different amino acids found in proteins of the human body. Of these amino acids, 10 are termed essential amino acids, which cannot be synthesized, and thus must be ingested. Sources of protein include meats, eggs, milk, nuts, legumes, whole grains, and various fruits and vegetables.
