| inverse | 1. Opposite in order, relation, or effect; reversed; inverted; reciprocal; opposed to direct. 2. <botany> Inverted; having a position or mode of attachment the reverse of that which is usual. 3. <mathematics> Opposite in nature and effect; said with reference to any two operations, which, when both are performed in succession upon any quantity, reproduce that quantity; as, multiplication is the inverse operation to division. The symbol of an inverse operation is the symbol of the direct operation with -1 as an index. Thus sin -1 x means the arc whose sine is x. <geometry> Inverse figures, two points lying on a line drawn from the center of a fixed circle or sphere, and so related that the product of their distances from the center of the circle or sphere is equal to the square of the radius. <mathematics> Inverse, or Reciprocal, ratio, the ratio of the reciprocals of two quantities. Inverse, or Reciprocal, proportion, an equality between a direct ratio and a reciprocal ratio; thus, 4: 2:: 1/3: 1/6, or 4: 2:: 3: 6, inversely. Origin: L. Inversus, p. P. Of invertere: cf. F. Inverse. See Invert. Source: Websters Dictionary (01 Mar 1998) |

| inverse anaphylaxis | Anaphylactic shock in an animal (e.g., guinea pig) whose tissues contain Forssman antigen, resulting from an intravenous injection of serum that contains Forssman's antibody. (05 Mar 2000) |
| inverse density dependence | <epidemiology> See density dependence. (05 Dec 1998) |
| inverse ocular bobbing | Slow downward eye movement followed by delayed quick upward return. (05 Mar 2000) |
| inverse square law | As applied to point sources, the intensity of radiation diminishes in proportion to the square of the distance from the source. (05 Mar 2000) |
| inverse symmetry | Correspondence of the right or left side of an asymmetrical individual to the left or right side of another. (05 Mar 2000) |
| inverse syntropy | A situation in which the presence of one disease tends to decrease the possibility of another. (05 Mar 2000) |
| substrate | <chemistry> A substance upon which an enzyme acts. Origin: L. Stratum = layer (18 Nov 1997) |
| substrate cycle | <biochemistry> Any seqence of enzyme catalysed reactions in which the forward and reverse processes (catalysed by different enzymes) are consititutively active. Frequently used to describe the cycle of phosphorylation and dephosphorylation of phosphatidyl inositol derivatives in cell membranes. (05 Jan 1998) |
| substrate cycling | A set of opposing, nonequilibrium reactions catalyzed by different enzymes which act simultaneously, with at least one of the reactions driven by ATP hydrolysis. The results of the cycle are that ATP energy is depleted, heat is produced and no net substrate-to-product conversion is achieved. Examples of substrate cycling are cycling of gluconeogenesis and glycolysis pathways and cycling of the triglycerides and fatty acid pathways. Rates of substrate cycling may be increased many-fold in association with hypermetabolic states resulting from severe burns, cold exposure, hyperthyroidism, or acute exercise. (12 Dec 1998) |
| substrate inhibition | Inhibition of an enzyme activity by a substrate of the reaction catalyzed by that enzyme; often, this type of inhibition occurs at elevated substrate levels in which the substrate is binding to a second, non-active site on the enzyme. (05 Mar 2000) |
| substrate-level phosphorylation | Synthesis of high-energy phosphate bonds through reaction of inorganic phosphate with an activated (usually) organic substrate. (09 Oct 1997) |
| substrate specificity | A characteristic feature of enzyme activity in relation to the kind of substrate on which the enzyme or catalytic molecule reacts. (12 Dec 1998) |
| suicide substrate | A competitive inhibitor that is converted to an irreversible inhibitor at the active site of the enzyme. Synonym: mechanism-based inhibitor. (05 Mar 2000) |
| insulin receptor substrate-1 protein | <chemical> Amino acid sequence given in first source; a 180 kD protein that contains multiple phosphorylated tyrosine residues after insulin stimulation; human and rat forms (hirs-1 and irs-1) are homologous Synonym: insulin receptor substrate-1-like protein, irs-1 protein, irs-1 gene product, hirs-1 protein, hirs-1 gene product, insulin receptor substrate 1, insulin receptor substrate-1 (05 Dec 1998) |
