英语化学问题, 急用~~According to the Lewis theory of acids and bases an acid is a proton donor and a base is a proton acceptor. 这句话对不对? 还是应该according to Bronsted Lowry theory ? 急用 谢谢~~ 答案 应该是后一种 According to Bronsted Lowry theory.原因是:布朗特(Bronsted)的酸碱质子...
A base is a substance that neutralizes an acid. A base which is soluble in water is called an alkali. 碱就是能中和酸的物质。注意base和alkali的区别。 另一种定义: A Bronsted-Lowry acid is a proton donor. 酸就是能提供氢离子(即质子)的物质。 A Bronsted-Lowry base is a proton acceptor....

If the proton donor is fixed and the proton acceptor is varied when one system is fit into the linear function, the k and α so obtained are functions of donor's proton affinity, PA(D). Therefore, it is possible to obtain a universal equation to calculate hydrogen bond strength in a ...
portion of R5P was from Xu5P and a small portion was from TAL and TKT1 reactions (Fig.5a). The observed mutation in thealsRpromoter may have supported this scenario by altering the expression ofrpiB. AlsR is a transcriptional repressor ofrpiB58, the encoded RpiB is the second ribose-5...
We hypothesized that the COSY-dependent proton exchange phenomenon at C2 of coumarin biosynthesis is directly linked to COSY’s catalytic function in mediating thetrans-to-cisisomerization of theo-hydroxylated hydroxycinnamoyl-CoA substrate. To identify residues that may be involved in the acid-base ...
