Inhibitor
inhibitor[in′hib·əd·ər] (aerospace engineering) A substance bonded, taped, or dip-dried onto a solid propellant to restrict the burning surface and to give direction to the burning process. (chemistry) A substance which is capable of stopping or retarding a chemical reaction; to be technically useful, it must be effective in low concentration. Inhibitor a circuit having m + n inputs and a single output, at which a signal can appear only when there are no signals on the m inputs (inhibiting). The other n inputs (principal) form one of the two logic connections, “AND” or “OR.” Inhibitors are used extensively in computers. They are very often understood to be a circuit having a single principal input and a single inhibiting input. A signal appears at the output of such a circuit when a signal is present on the principal input but there is none on the inhibiting input. Such an inhibitor is called an anticoincidence gate; its conventional representation is given in Figure 1.  Figure 1. Block diagram of an anticoincidence gate (inhibitor) with m — 1 and n 1:(A) principal input, (Q) inhibiting input, (Ga) anticoincidence gate
inhibitorA substance added to paint to retard drying, skinning, mildew growth, etc. Also see corrosion inhibitor, inhibiting pigment, drying inhibitor.inhibitor
inhibitor [in-hib´ĭ-tor] 1. any substance that interferes with a chemical reaction, growth, or other biologic activity.2. a chemical substance that inhibits or checks the action of a tissue organizer or the growth of microorganisms.3. an effector that reduces the catalytic activity of an enzyme.ACE i's (angiotensin-converting enzyme i's) see angiotensin-converting enzyme inhibitors.angiogenesis inhibitor a group of drugs that prevent growth of new blood vessels into a solid tumor.aromatase i's a class of drugs that inhibit aromatase activity and thus block production of estrogens; used to treat breast cancer and endometriosis.C1 inhibitor (C1 INH) a member of the serpin group, an inhibitor of C1, the initial component activated in the pathway" >classical complement pathway.
