| zinc compounds | Inorganic compounds that contain zinc as an integral part of the molecule. (12 Dec 1998) |
|---|---|
| zinc D-Ala-D-Ala carboxypeptidase | <enzyme> Involved in last step of peptidoglycan synthesis; resistant to penicillin; see also record for d-alanyl-d-alanine serine peptidases Registry number: EC 3.4.17.14 Synonym: d-alanyl-d-alanine peptidase, zn(2+)g, zn(2+)g d-ala-d-ala peptidase, zn-ala-ala peptidase, zn(2+)g d-alanyl-d-alanine peptidase (26 Jun 1999) |
| zinc deficiency | : Deficiency of zinc is associated with short stature, anaemia, increased pigmentation of skin (hyperpigmentation), enlarged liver and spleen (hepatosplenomegaly), impaired gonadal function (hypogonadism), impaired wound healing, and immune deficiency. (for a genetic disorder that impairs zinc uptake, please see acrodermatitis enteropathica). According to the national academy of sciences, the recommended dietary allowances of zinc are 12 milligrams per day for women and 10 milligrams per day for men. Food sources of zinc include meat including liver, eggs, seafood, nuts and cereal. (12 Dec 1998) |
| zinc excess | Too much zinc can cause gastrointestinal irritation (upset stomach), interfere with copper absorption and cause copper deficiency, and (like too little zinc) cause immune deficiency. According to the national academy of sciences, the recommended dietary allowances of zinc are 12 milligrams per day for women and 10 milligrams per day for men. (12 Dec 1998) |
| zinc finger | <molecular biology> A specialised protein group that is characterised by a single zinc atom associated with DNA binding proteins. A loop of 12 amino acids contains either 2 cysteine and 2 histidine groups (a cysteine histidine zinc finger) or 4 cysteines (a cysteine cysteine zinc finger), that directly co ordinate a zinc atom. The loops (usually present in multiples) intercalate directly into the DNA helix. Originally identified in the RNA polymerase III transcription factor TFIIIA. (18 Nov 1997) |
| zinc fingers | Domains in DNA- and RNA-binding proteins that contain amino acids which are folded into a single structural unit around a zinc atom that links two cysteines and two histidines. Each finger is postulated to recognise a specific sequence of about five nucleotide pairs. (12 Dec 1998) |
| zinc fume fever | An occupational disease, characterised by malaria-like symptoms, due to inhalation of particles and fumes of metallic oxides. Fumes are formed by evaporation at very high temperature and condensation in air into fine particles. Synonym: brass founder's ague, foundryman's fever, metal fume fever, zinc fume fever. (05 Mar 2000) |
| zinc gelatin | Zinc oxide, gelatin, glycerin, and purified water; used topically as a protectant. (05 Mar 2000) |
| zinc iodide | ZnI2;has been used as an antiseptic and astringent. (05 Mar 2000) |
| zinc isotopes | Stable zinc atoms that have the same atomic number as the element zinc, but differ in atomic weight. Zn-66-68, and 70 are stable zinc isotopes. (12 Dec 1998) |
| zinc permanganate | Action is similar to that of potassium permanganate, but more astringent; used in urethritis, by injection or douche in a 1:4000 solution. (05 Mar 2000) |
| zinc peroxide | ZnO2;a yellowish white powder, insoluble in water and decomposed by acids; used in pharmaceutical preparations. Synonym: zinc superoxide. (05 Mar 2000) |
| zinc phenolsulfonate | Used as an intestinal antiseptic and locally as an astringent in chronic inflammation of the mucous membranes. Synonym: zinc sulfocarbolate. (05 Mar 2000) |
| zinc phosphate cement | <chemical> A material used for cementation of inlays, crowns, bridges, and orthodontic appliances and occasionally as a temporary restoration. It is prepared by mixing zinc oxide and magnesium oxide powders with a liquid consisting principally of phosphoric acid, water, and buffers. Chemical name: Phosphoric acid, zinc salt (2:3) (12 Dec 1998) |
| zinc phosphide | Zn3P2;used as a bait poison for the extermination of rats and mice. (05 Mar 2000) |
