However, if the solution is also made in sodium ethoxide after the same treatment , the major product is found to be 4-t-butylcyclohexene.

然而，如果是在乙氧基钠中经过同样的处理则主要产物是4-t-丁基环己烯。

During the titration of Ca〓CaM by La〓, the hydrid complex La〓Ca〓CaM forms as the intermediate species. La〓 can bind to calmodulin with high affinity (K〓=10nmol/L) and obvious cooperation between the two global domains. The secondary structure of La〓CaM and Ca〓CaM are highly similar, but there are obvious differences in ternary structures. Excessive La〓 changes the conformation of calmodulin greatly.

实验结果表明，La〓在钙调蛋白上的结合位点与钙离子相同；在结合顺序上La〓以较小的优势先结合在钙调蛋白的N末端；La〓Ca〓CaM是La〓与含钙的钙调蛋白作用时的主要产物；La〓强烈地与钙调蛋白结合，其解离常数约10nmol/L，各个结合位点之间存在明显的协同效应；La〓CaM与Ca〓CaM在二级结构上高度相似，但是在高级结构上有明显差异。

The effects of temperature, organic acids and residence time on the yields of 5-hydromethylfurfural (5-HMF) and levulinic acid were investigated.
