聯苯物 的英文怎麼說
中文拼音 [liánběnwù]
聯苯物
英文
phenylog-
Such as when the substrates was benzidine and a - naphthol, the absortion peak was 450nm after catalyticed by dna, and 501nm after catalyticed by pod, if changing substrate to benzidine and pyrocatechol, the absortion peak was 503nm after catalyticed by dna and 603nm after catalyticed by pod. the second difference was the different result after hplc : the result of hplc ( substrates : benzidine and a - naphthol ) showed that the products under the affect of dna and pod had different value on the peak and the area
