説明2,5-Di-tert-butylhydroquinone, also known as 2,5-TBHQ or DTBHQ, belongs to the class of organic compounds known as phenylpropanes. These are organic compounds containing a phenylpropane moiety. It is a phenol derivative containing 2 phenol groups and 2 alkyl groups, each consisting of three methyl groups.
使用2,5-Di-tert-butylhydroquinone is the oxidation substrate used to measure the catalytic activity of the copper(II) enzyme-like catalysts.
一般的な説明Mobilizes Ca2+ specifically from the Ins(1,4,5)P3-sensitive Ca2+ stores by inhibiting microsomal and sarcoplasmic reticulum Ca2+-ATPase activity. Does not affect mitochondrial Ca2+ fluxes or plasma membrane Ca2+/Mg2+ ATPase activity. Useful for the study of endomembrane Ca2+ stores and plasma membrane Ca2+ permeability pathways.
