Biological Half-life

It mimics calcium and therefore gets trapped in bone. This gives it a long biological half-life to go with its long physical half-life, making it doubly dangerous. Technetium, 99m Tc, is one of the favorites for diagnostic scans because of short physical and biological half-lives. It clears from the body very quickly after the imaging procedures.

What Are the Functions of Calcium in the Body? - dummies

Calcium is tightly linked to many of the roles that vitamin D plays in the body. In bone health (and other physiologic systems), calcium is a key player. Calcium is a mineral that must be constantly eaten to build bone and maintain the blood level of calcium. When people hear about calcium…

Ethylene oxide - Wikipedia

Ethylene oxide is an organic compound with the formula C 2 H 4 O.It is a cyclic ether and the simplest epoxide: a three-meered ring consisting of one oxygen atom and two carbon atoms.Ethylene oxide is a colorless and flammable gas with a faintly sweet odor. Because it is a strained ring, ethylene oxide easily participates in a nuer of addition reactions that result in ring-opening.

Chemistry of ascorbic acid - Wikipedia

History. The antiscorbutic properties of certain foods were demonstrated in the 18th century by James Lind.In 1907, Axel Holst and Theodor Frølich discovered that the antiscorbutic factor was a water-soluble chemical substance, distinct from the one that prevented beriberi.Between 1928 and 1932, Albert Szent-Györgyi isolated a candidate for this substance, which he called it "hexuronic acid

Calcium: isolation. Isolation: calcium metal is readily available commercially and there is no need to make it in the laboratory.Commercially it can be made by the electrolysis of molten calcium chloride, CaCl 2.. hode: Ca 2+ (l) + 2e-→ Ca. anode: Cl-(l) → 1 / 2 Cl 2 (g) + e-. The calcium chloride is made by the action of hydrochloric acid upon calcium carbonate.

Lead(II) nitrate - Wikipedia

Lead(II) nitrate is an inorganic compound with the chemical formula Pb(NO 3) 2.It commonly occurs as a colourless crystal or white powder and, unlike most other lead(II) salts, is soluble in water..

Structure-activity relationship studies in the field of

A series of xanthone 1,4-dihydropyridine derivatives bearing a 2,3-lactone ring and a 2-acetoxymethyl group were prepared. The compounds were evaluated for inotropic, chronotropic and calcium antagonist properties. The introduction of a 2,3-lactone ring improved the negative inotropic activity and selectivity.
