| dextronic | <chemistry> Pertaining to, or derived from, dextrose; as, dextronic acid. Dextronic acid, a sirupy substance obtained by the partial oxidation of various carbohydrates, as dextrose, etc. Source: Websters Dictionary (01 Mar 1998) |
| dextropedal | Denoting one who uses the right leg in preference to the left. Synonym: right-footed. Origin: dextro-+ L. Pes (ped-), foot (05 Mar 2000) |
| dextroposition | Move to the right. (12 Dec 1998) |
| dextroposition of the heart | The heart is displaced to the right (from its usual location in the left chest). There is no anatomic alteration in the heart itself, just in its location. Dextroposition occurs when the contents of the left side of the chest shove the heart to the right or when the contents of the right chest are reduced (for example, by collapse of the right lung) and the heart moves toward the sparsely occupied space on the right.

| dextropropoxyphene hydrochloride | (+)-alpha-4-(dimethylamino)-3-methyl-1,2-diphenyl-2-butanol propionate hydrochloride;a nonantipyretic, orally effective weak narcotic analgesic structurally related to methadone and used for the relief of mild to moderate pain; it is less effective than codeine. Synonym: dextropropoxyphene hydrochloride. (05 Mar 2000) |
| dextropropoxyphene napsylate | Mono-2-naphthalenesulfonate monohydrate salt of propoxyphene;a weak narcotic analgesic. Synonym: dextropropoxyphene napsylate. (05 Mar 2000) |

| dextrorotation | A turning or twisting to the right; especially, the clockwise twist given the plane of plane-polarised light by solutions of certain optically active substances. Compare: levorotation. (05 Mar 2000) |
| dextrorotatory | <chemistry> A chiral molecule which rotates plane-polarized light to the right. (09 Jan 1998) |
| dextrorotatory isomer | A stereoisomer that does a clockwise rotation of plane-polarized light. (09 Oct 1997) |
| dextrorphan | <chemical> Dextro form of levorphanol. It acts as a noncompetitive nmda receptor antagonist, among other effects, and has been proposed as a neuroprotective agent. It is also a metabolite of dextromethorphan. Pharmacological action: excitatory amino acid antagonists, neuroprotective agents. Chemical name: Morphinan-3-ol, 17-methyl-, (9alpha,13alpha,14alpha)- (12 Dec 1998) |
| dextrorse | Turning from the left to the right, in the ascending line, as in the spiral inclination of the stem of the common morning-glory. at present scientists predicate dextrorse or sinistrorse quality of the plant regarded objectively; formerly the plant was regarded subjectively, and what is now called dextrorse was then considered sinistrorse.
