Bioconcentration. In aquatic toxicology, bioconcentration is the accumulation of a water-borne chemical substance in an organism exposed to the water. [1][2] There are several ways in which to measure and assess bioaccumulation and bioconcentration. These include: octanol-water partition coefficients (K OW), bioconcentration factors (BCF ...
Tris (pentafluorophenyl)borane, sometimes referred to as "BCF", is the chemical compound (C6F5)3B. It is a white, volatile solid. The molecule consists of three pentafluorophenyl groups attached in a "paddle-wheel" manner to a central boron atom; the BC3 core is planar. It has been described as the “ideal Lewis acid ” because of its high ...
Infobox references. Arachidonic acid 5-hydroperoxide (5-hydroperoxyeicosatetraenoic acid, 5-HPETE) is an intermediate in the metabolism of arachidonic acid by the ALOX5 enzyme in humans or Alox5 enzyme in other mammals. The intermediate is then further metabolized to: a) leukotriene A4 which is then metabolized to the chemotactic factor for ...
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1 ]
Beginning Oct. 1, any woman can also order the test from the company’s website by having one of Sera's writing providers review the request. The test kit and instructions are sent to expectant ...
Infobox references. Sodium 1,3-dithiole-2-thione-4,5-dithiolate is the organosulfur compound with the formula Na 2 C 3 S 5, abbreviated Na 2 dmit. It is the sodium salt of the conjugate base of the 4,5-bis (sulfanyl)-2 H - 1,3-dithiole -2-thione. The salt is a precursor to dithiolene complexes and tetrathiafulvalenes.
The recommended dietary allowance for protein is 0.8 grams of per kilogram of body weight daily — so for an adult weighing 150 pounds, about 54 grams of protein a day, for example.
The 5.8S rRNA is initially transcribed along with the 18S and 28S rRNA in the 45S preribosomal RNA, along with the ITS 1 and ITS 2 (Internal transcribed spacer) and a 5’ and 3’ ETS (External transcribed spacer). [8] The 5.8S rRNA is located between the two ITS regions, with ITS1 separating it from the 18S rRNA in the 5' direction, and ITS2 ...
