Best Price Selenium Enrich Yeast




Products Description


Selenium-enriched yeast , produced by fermenting Saccharomyces cerevisiae in a selenium-rich media, is a recognized source of organic food-form selenium. In this process, virtually all of the selenium structurally substitutes for sulfur in the amino acid methionine thus forming selenomethionine via the same pathways and enzymes that are used to form sulfur-containing methionine.
Owing to its similarity to S-containing methionine, selenomethionine is taken up nonspecifically and becomes part of yeast
protein. It is this metabolic route that makes selenium-enriched yeast valuable in animal and human nutrition, since
selenium-enriched yeast offers the same organic form of selenium produced by food-chain autotrophs.
