Description: Selenomethionine is the major form of selenium in plant foods. Selenomethionine is identical to methionine, except that selenium replaces the sulfur atom. The selenium consumed as selenocysteine is broken down to form alanine and hydrogen selenide (H2Se). The breakdown pathway of selenomethion- ine is not clear. Although selenium does not occur to a great extent as selenite in foods, selenite is readily used as a source of the element by humans and animals. Selenium also occurs as selenate in foods such as beet leaves, garlic, and cabbage.
Uses:
1. As a natural organic selenium source in life, DL selenomethionine is gradually replacing inorganic compounds such as sodium selenite and becoming a good source of selenium supplement. It is also an intermediate for the preparation of other selenium containing drugs and has become the focus of the development of selenium compounds.
2. It can be used as intermediate of medicine and health care products and feed additive
