From the perspective of cultural science, the author expatiated on two different trends of further devel-opment of oriental and western sports cultures during globalization, considered that oriental and western sports de-veloped under the background of two different cultures are heterogeneously commensal in terms of cultural nature, yet isomorphic in terms of cultural structure.

摘 要：从文化学视角，论述了全球化时代东西方体育文化未来发展的两种不同走向，认为在两种不同文化背景下发展起来的东西体育文化本质是异质共生的，然而在文化结构上具有同构性。

The results showed that though apoHb could be reconstituted with all FePs, it showed different functions. Binding of apoHb with hemin can enhance the heterolytic cleavage of O-O bond of H〓O〓, but inhibiting the cleavage when FeTCPP and FeTPPS〓 were used instead of hemin. The binding of apoHb with FeTTMAPP showed negligible influence on the cleavage of O-O bond in H〓O〓.

结果表明，虽然具有阴离子基团的FeTCPP和FeTPPS〓能够在天然血红蛋白中辅基位置的附近与脱辅基血红蛋白结合，但是由于结构上与天然辅基的差别，使得血红素蛋白中相应的氨基酸残基不能起到有效的作用，因此不但不能提高反而抑制了其过氧化物酶活性；而对于具有阳离子基团的FeTTMAPP，脱辅基血红蛋白对其活性没有明显的影响。

One of the synthetic methods of the MAP is to connect subsequent amino acid one by one with the lysine belonging to the lysine-tree scaffolding. Because of the steric hinderance effect, synthesis becomes more and more difficult. And for so many crippled peptides in the MAP, the reactivity of it is not so good.

将支架结构上的氨基酸作为合成的结合位点，按照常规方法依次进行后续氨基酸的连接，由于空间位阻效应，后续氨基酸的连接困难度增加，八分支肽中的残缺肽较多，由此方法合成的分支肽反应活性较低。
