产品介绍 |
甲萘醌9是一种维生素K2,可作为促血栓形成剂。研究表明,在有氧和光的情况下,甲萘醌在最靠近醌环的异戊二烯单元易受快速光氧化作用。此外,甲萘醌9是硝酸还原酶中的功能性电子转移组分。甲萘醌9可以通过紫外光谱在248 nm处检测到。已知甲萘醌作为中间体,可从每个NADH分子接受2个电子,并将其转移到其他分子上,用于细菌中的厌氧呼吸。另外,维生素K可以被维生素K环氧化物还原酶还原。 Menaquinone 9 is a form of vitamin K2 which acts as a prothrombogenic agent. Studies suggest that menaquinones are susceptible to rapid photooxidation at the isoprene unit closest to the quinone ring in the presence of oxygen and light. In addition, Menaquinone 9 is a functional electron transfer component in nitrate reductase. Menaquinone 9 can be detected in samples via UV spectroscopy at 248 nm. It is known that menaquinones act as intermediates accepting 2 electrons from each NADH molecule and transferring them to other molecules for anaerobic respiration in bacteria. Addditionally, vitamin K can be reduced by the enzyme vitamin K epoxide reductase. |
