Essential for life, proteins are complex organic compounds found in every human cell and present in a major part of the skin, muscles, glands and organs. Proteins take on different functions in the form of enzymes, hormones, antibodies and globulins in order to sustain the body's chemistry. Found in animal- and plant-based foods, proteins are classified as incomplete or complete – complete meaning the source contains all nine essential amino acids, while incomplete means it lacks one or more.
