C

1. Abbreviation or symbol for large calorie; carbon; cathodal; cathode; Celsius; cervical vertebra (C1–C7); closure (of an electrical circuit); congius (gallon); contraction; coulomb; curie; cylinder; cylindrical lens; cytidine; cysteine; cytosine; component of complement (C1–C9); third substrate in a multisubstrate enzyme-catalyzed reaction. 2. When followed by subscript letters, e.g., C_in, indicates renal clearance of a substance ( e.g., inulin). When followed by subscript numbers, e.g., C₁₉, indicates the number of carbon atoms in a molecule, e.g., 19.
