The compound, Cs 3 CdH 5, prepared by the reaction of caesium hydride, CsH, and cadmium metal powder at high temperature contains the CdH 2− 4 ion, along with caesium cations, Cs +, and hydride anions, H −. The tetrahedral anion is an example of an ionic complex of CdH 2. The average Cd-H bond length in CdH 2− 4 is 182pm.
Cetrimonium bromide, also known with the abbreviation CTAB, is a quaternary ammonium surfactant with a condensed structural formula [ (C 16 H 33 )N (CH 3) 3 ]Br. It is one of the components of the topical antiseptic cetrimide. [1] The cetrimonium (hexadecyltrimethylammonium) cation is an effective antiseptic agent against bacteria and fungi.
proteins. In enzymology, a cellobiose dehydrogenase (acceptor) ( EC 1.1.99.18) is an enzyme that catalyzes the chemical reaction. cellobiose + acceptor cellobiono-1,5-lactone + reduced acceptor. Thus, the two substrates of this enzyme are cellobiose and acceptor, whereas its two products are cellobiono-1,5-lactone and reduced acceptor .
α-Cyclodextrin ( alpha -cyclodextrin), sometimes abbreviated as α-CD, is a hexa saccharide derived from glucose. It is related to the β- (beta) and γ- (gamma) cyclodextrins, which contain seven and eight glucose units, respectively. All cyclodextrins are white, water-soluble solids with minimal toxicity.
