The results showed that the content of Se element in the Se-MT was 2.5 folds higher than that of Zn-MT, on the contrary the content of sulfur element in Se-MT was 2 folds lower then Zn-MT, C, H, N contents in MT were no significant differences in both groups. In terms of chemical property, the element of selenium is very similar to sulfur because they are in the same group in the periodic table. The above results illustrated that the Se could replace S from SH-sulfhydryl to SeH-selenihydryl in cysteine, which presents the existence of a novel Se-MT.

结果表明Se－MT中Se元素含量高于Zn－MTZ.5倍左右，而 S元素含量低于 ZnMT 2倍左右，C、H、N元素含量无明显差异，这说明了麦硒康诱导后Se仙T分子结构上的差异，由于Se元素与S元素同属氧族元素，在化学性质上极为相似，故Se元素极可能替代了MT的合成过程中所必需半味氨酸残基中的SH一基因上的S元素成为SeH一基团，这样我们就得到了一种含SeH一基团的新型Se－MT。
