Peptidyl-prolyl cis/trans isomerization is of considerable biological significance and prolyl residue plays an important role in the final structure of proteins.
25nm,同一性(identity)<30％的2401条肽链中计算提取了全部顺式与反式脯氨酸肽键的位置,数目分别为1221个与26401个,从而建立了一个较大规模的脯氨酸肽键数据集。
A Study on Preparation of Cis-pinane in Pinene Hydrogenation;
蒎烯催化加氢制备顺式蒎烷
Study on Synthesis of cis-Pinane by Catalytic Hydrogenation of α-Pinene;
α-蒎烯催化加氢制备顺式蒎烷的研究
Nanometer nickel was first used in hydrogenation of α-pinene: the conversion rate of raw material with nanometer nickel as catalyst was higher than that of Raney nickel and the selectivity of cis-pinane was higher than that with Pd/C.
