[13] Inhibition of the enzyme occurs by removal and chelation of the metal ion required for catalytic activity, leaving an inactive apoenzyme. Shanghai Jizhi Biochemical Technology Co., Ltd. Phenanthrene is a polycyclic aromatic hydrocarbon (PAH) and has been frequently used as an indicator for monitoring PAH contaminated matrices[1]. Anthracene can be tethered to other cyclic dienes by alkyl or ethylenglycol chains, for example, in dendrimers with anthracene cores. Pyrene is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, resulting in a flat aromatic system. Phenanthrene is generally used for dye production, synthetic resin, preservative. Buying Leads | %PDF-1.4 Melting points were determined on a Gallenkamp melting point apparatus and are uncorrected.
