By studying the process of treating selenium in ethylenediamine, we proposed the mechanism of the preparation of selenides under solvothermal condition. The selenides came into being from the reaction of metal ions with Se〓, which was obtained by the amine attacking selenium.

Hydrogen selenide：硒化氢

硒酸盐和亚硒酸盐的毒性较大,硒化氢(hydrogen selenide)的毒性最大,是一种气状的硒化合物. 有机态硒化物如甲硒胺酸和硒胺酸与含硫氨基酸相似,因此毒性较无机态硒为低,但其吸收率高,虽不致造成急性毒害,但长期大量摄取,会产生与无机硒相似的中毒症状.

selenite：亚硒酸盐

甲硒胺酸的吸收效率比亚硒酸盐(selenite)来的好. 含有硒的胺基酸吸收是利用胺基酸运送系统,吸收率可达到80%. 甲硒胺酸的吸收率比硒胺酸好. 在某些研究中亚硒酸盐的吸收率可达到85%以上,因与肠道中物质的交互作用,吸收率较有变化.
