Summary. Flavin adenine dinucleotide (FAD) is an important redox cofactor involved in many reactions in metabolism. The fully oxidized form, FAD,is converted to the reduced form, FADH2by receiving two electrons and two protons. Which process reduces FAD?
The protons in a nucleus being equal with the electrons outside, the atom is electrically neutral. 点击查看答案 第3题 Use the appropriate molecular orbital enerry diagram to write the electron configuration for each of the following molecules or ions,calculate the bond order of each,and predict...
Every atom in the aromatic ring must have a p orbital. The ring must contain pi electrons. Where are aromatic compounds found? Compounds containing two benzene rings joined together, such as naphthalene, are also found in crude oil, though they are much rarer than benzene-related compounds. Ar...
