  2. Zinc in biology - Wikipedia

    en.wikipedia.org/wiki/Zinc_in_biology

    Zinc fingers help read DNA sequences.. Zinc is an essential trace element for humans [1] [2] [3] and other animals, [4] for plants [5] and for microorganisms. [6] Zinc is required for the function of over 300 enzymes and 1000 transcription factors, [3] and is stored and transferred in metallothioneins.

  3. Zinc gluconate - Wikipedia

    en.wikipedia.org/wiki/Zinc_gluconate

    Zinc gluconate dietary supplements. Zinc gluconate is the zinc salt of gluconic acid.It is an ionic compound consisting of two anions of gluconate for each zinc(II) cation.Zinc gluconate is a popular form for the delivery of zinc as a dietary supplement providing 14.35% elemental zinc by weight.

  4. Isotopes of zinc - Wikipedia

    en.wikipedia.org/wiki/Isotopes_of_zinc

    Naturally occurring zinc (30 Zn) is composed of the 5 stable isotopes 64 Zn, 66 Zn, 67 Zn, 68 Zn, and 70 Zn with 64 Zn being the most abundant (48.6% natural abundance).Twenty-eight radioisotopes have been characterised with the most stable being 65 Zn with a half-life of 244.26 days, and then 72 Zn with a half-life of 46.5 hours.

    For example, terpyridine, which is a tridentate ligand forms the complex [Zn(terpy)Cl 2]. Another example would involve a tripodal ligand such as Tris(2-aminoethyl)amine. Square pyramidal 5-coordinate Zinc is found in Tetra(4-pyridyl)porphinatomonopyridinezinc(II) [ 19 ] Solution studies of other 5-coordinate Zinc porphyrins have been reported.

  6. Isotopic labeling - Wikipedia

    en.wikipedia.org/wiki/Isotopic_labeling

    A carbon-13 label was used to determine the mechanism in the 1,2- to 1,3-didehydrobenzene conversion of the phenyl substituted aryne precursor 1 to acenaphthylene. [3]An isotopic tracer, (also "isotopic marker" or "isotopic label"), is used in chemistry and biochemistry to help understand chemical reactions and interactions.

  7. Zinc - Wikipedia

    en.wikipedia.org/wiki/Zinc

    Zn, the most abundant isotope of zinc, is very susceptible to neutron activation, being transmuted into the highly radioactive 65 Zn, which has a half-life of 244 days and produces intense gamma radiation. Because of this, zinc oxide used in nuclear reactors as an anti-corrosion agent is depleted of 64 Zn before use, this is called depleted ...

  8. Zinc pyrithione - Wikipedia

    en.wikipedia.org/wiki/Zinc_pyrithione

    The pyrithione ligands, which are formally monoanions, are chelated to Zn 2+ via oxygen and sulfur centers. In the crystalline state, zinc pyrithione exists as a centrosymmetric dimer (see figure), where each zinc is bonded to two sulfur and three oxygen centers. [3] In solution, however, the dimers dissociate via scission of one Zn-O bond ...

    Although initial results were promising, the project was abandoned. A variety of adverse results prevented the method's adoption. Most infamously, the final prototype suffered damage in a series of diethylzinc explosions from trace amounts of water vapor in the chamber. This led the authors of the study to humorously comment:
