| Hoffmann's muscular atrophy | Transmitted as autosomal recessive on chromosome 5q.

| Hoffmann's reflex | <clinical sign> In latent tetany mild mechanical stimulation of the trigeminal nerve causes severe pain, flexion of the terminal phalanx of the thumb and of the second and third phalanges of one or more of the fingers when the volar surface of the terminal phalanx of the fingers is flicked. Synonym: digital reflex, Hoffmann's reflex, snapping reflex. (05 Mar 2000) |

| van't Hoff's equation | Equation for osmotic pressure of dilute solutions. See: van't Hoff's law. For any reaction, d(ln Keq/d(1/T) equals -dH/R where Keq is the equilibrium constant, T the absolute temperature, R is the universal gas constant, and dH is the change in enthalpy; thus, plotting ln Keq vs. 1/T allows the determination of dH. (05 Mar 2000) |
| van't Hoff's law | In stereochemistry, all optically active substances have one or more multivalent atoms united to four different atoms or radicals so as to form in space an unsymmetrical arrangement, the osmotic pressure exerted by any substance in very dilute solution is the same that it would exert if present as gas in the same volume as that of the solution; or, at constant temperature, the osmotic pressure of dilute solutions is proportional to the concentration (number of molecules) of the dissolved substance; i.e., the osmotic pressure, π, in dilute solutions is π = RTσci, where R is the universal gas constant, T is the absolute temperature, and ci is the molar concentration of solute i, the rate of chemical reactions increases between two-and three-fold for each 10캜 rise in temperature. (05 Mar 2000) |
| van't Hoff's theory | That substances in dilute solution obey the gas laws. Compare: van't Hoff's law. (05 Mar 2000) |
| Le Bel-van't Hoff rule | The number of stereoisomers of an organic compound is 2n where n represents the number of asymmetric carbon atoms (unless there is an internal plane of symmetry). A corollary of their simultaneously announced conclusions, in 1874, that the most probable orientation of the bonds of a carbon atom linked to four groups or atoms is toward the apexes of a tetrahedron, and that this accounted for all then-known phenomena of molecular asymmetry (which involved a carbon atom bearing four different atoms or groups). See: stereoisomerism. (05 Mar 2000) |
| Hoffmann's sign |
1. see under phenomenon. 2. in hemiplegia, a sudden nipping of the nail of the index, middle, or ring finger will produce flexion of the terminal phalanx of the thumb and of the second and third phalanges of some other finger; called also digital reflex and Hoffmann's reflex.
