Bromoform

Bromoform is produced naturally by phytoplankton and seaweeds in the ocean and this is thought to be the predominant source to the environment . However locally significant amounts of bromoform enter the environment formed as disinfection byproducts known as the trihalomethanes when chlorine is added to drinking water to kill bacteria. It is somewhat soluble in water and readily evaporates into the air.Bromoform, a haloform, is used as a solvent for waxes, greases, and oils.Bromoform is used as an ingredient in fire resistant chemicals and in fluid gauges. It is also used as an intermediate in manufacturing agrochemical and organic synthesis. It is also used as a polymerization agent, as a sedative, and as a cough suppression agent in medical field. Bromoform is a heavy liquid used for th

Carnitine

Carnitine is a quaternary ammonium compound involved in metabolism in most mammals, plants and some bacteria.Carnitine may exist in two isomers, labeled D-carnitine and L-carnitine, as they are optically active. Carnitine is involved in the oxidation of fatty acids, and involved in systemic primary carnitine deficiency. It has been studied for preventing and treating other conditions, and is used as a purported performance enhancing drug.Carnitine is involved in transporting fatty acids across the mitochondrial membrane, by forming a long chain acetylcarnitine ester and being transported by carnitine palmitoyltransferase I and carnitine palmitoyltransferase II. Carnitine also plays a role in stabilizing Acetyl-CoA and coenzyme A levels through the ability to receive or give an acetyl group.

Carnotite

Carnotite is a potassium uranium vanadate radioactive radioactive, bright-yellow, soft and earthy vanadium mineral that is an important source of uranium. A hydrated potassium uranyl vanadate, K2(UO2)2(VO4)2·3H2O, pure carnotite contains about 53 percent uranium, 12 percent vanadium, and trace amounts of radium. It is of secondary origin, having been formed by alteration of primary uranium-vanadium minerals. It occurs chiefly with tyuyamunite (its calcium analogue) in sandstone, either disseminated or locally as small pure masses, particularly around fossil wood.Carnotite has provided most of the uranium production from secondary deposits; it is also mined for vanadium and radium. From 1911 to 1923, ores containing carnotite were mined in Colorado for radium. From 1937 to 1943, carnotite was again mined, primarily for vanadium. After World War II it was mined extensively in the U.S. for uranium. The greatest known concentration of carnotite deposits is in the western U.S., particularly in the Colorado Plateau area. Other deposits occur in Wyoming, South Dakota, and Pennsylvania. Carnotite has been found in small quantities at many localities throughout the world; commercial deposits outside the U.S. occur near Kokand and Ferghana in eastern Uzbekistan.
