| crystal | A solid of regular shape and, for a given compound, characteristic angles, formed when an element or compound solidifies slowly enough, as a result either of freezing from the liquid form or of precipitating out of solution, to allow the individual molecules to take up regular positions with respect to one another. Origin: G. Krystallos, clear ice, crystal (05 Mar 2000) |

| crystal structure | <chemistry> The configuration in which atoms are arranged in a material. These arrangements have a direct effect on the physical properties of the material. These arrangements commonly take the form of cubes, rectangular solids, hexagonal solids. Etc. (05 Aug 1998) |
| crystal violet | Hexamethylpararosanilin chloride;a compound that has been used in the external treatment of burns, wounds, and fungal infections of skin and mucous membranes, and internally for pinworm and certain fluke infections; used also as a stain for chromatin, amyloid, platelets in blood, fibrin, and neuroglia, and to differentiate among bacteria. Synonym: methylrosaniline chloride. (05 Mar 2000) |

| crystallin | <cell biology> Major proteins of the vertebrate lens. Range from high MW oligomeric species to low MW monomeric species. Immunological cross reactivity suggests that the sequences of crystallin sub units are relatively highly conserved in evolution. (18 Nov 1997) |

| crystalline digitalin | <chemical> A cardiac glycoside sometimes used in place of digoxin. It has a longer half-life than digoxin; toxic effects, which are similar to those of digoxin, are longer lasting. Pharmacological action: anti-arrhythmia agents, cardiotonic agent, enzyme inhibitors. Chemical name: Card-20(22)-enolide, 3-((O-2,6-dideoxy-beta-D-ribo-hexopyranosyl-(1-4)-O-2,6-dideoxy-beta-D-ribo-hexopyranosyl-(1-4)-2,6-dideoxy-beta-D-ribo-hexopyranosyl)oxy)-14-hydroxy-, (3beta,5beta)- (12 Dec 1998) |

| crystalline interface | In dentistry, a boundary between adjacent crystals. (05 Mar 2000) |
| crystalline lens | <physics> A transparent optical element, so constructed that it serves to change the degree of convergence or divergence of the transmitted rays. (05 Aug 1998) |
| crystalline protein | <protein> The major protein found in the lens of the vertebrate eye, it can be dissolved in water easily. (09 Oct 1997) |
