| − | '''Proteins''' are complex organic compounds whose basic structure is a primary chain of amino acids covalently bonded via [[peptide bond]]s and folded into a certain shape. This tertiary fold dictates the function of the protein within the organism. They can take on many forms and perform distinct functions including (but certainly not limited to) structural, enzymatic, information storage, intracellular signaling, and transportation roles. In terms of structure, proteins are important in the construction and integrity of different body tissues including connective and muscular, as well as endocrine/exocrine glands.<ref> http://www.hsph.harvard.edu/nutritionsource/protein.html</ref> | + | '''Proteins''' are complex organic compounds whose basic structure is a primary chain of amino acids covalently bonded via [[peptide bond]]s and folded into a certain shape.
