Pyrroloquinoline quinone -PQQ(methoxatin disodium salt), an aromatic tricyclic o-quinone, is a redox cofactor for bacterial dehydrogenases. It is an efficient electron transfer catalyst from a number of organic substrates to molecular oxygen (O2), constructing quinoprotein model reactions.
Pyrroloquinoline quinone disodium salt(PQQ), a redox co-factor, is an anionic, redox-cycling orthoquinone. Pyrroloquinoline quinone disodium salt is isolated from cultures of methylotropic bacteria and tissues of mammals. Pyrroloquinoline quinone disodium salt is an essential nutrient for mammals and is important for immune functio.
动物 A (mg/kg) = 动物 B (mg/kg)×动物 B的Km系数/动物 A的Km系数 | |
例如,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
