WebAerobic degradation of biphenyl in all bacterial strains described to date involves an upper pathway catalyzing the conversion of biphenyl to benzoate and 2-hydroxypenta-2,4-dienoate (HPD), and a lower pathway for the conversion of HPD to compounds that enter the TCA cycle (reviewed in References 158 and 170; Figure 8).Depending on the strain, … WebIs biphenyl acidic or basic? You might wonder why this reaction is important? It is because it is a single replacement reaction. The sodium ion replaces the H+ ion on the alcohol. Get it? It replaces the H+ ion because the alcohol is an H+ donor.
