NameD-Isoleucine
SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
DescriptionD-Isoleucine, also known as DIL, belongs to the class of organic compounds known as isoleucine and derivatives. Isoleucine and derivatives are compounds containing isoleucine or a derivative thereof resulting from reaction of isoleucine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. D-Isoleucine is a very strong basic compound (based on its pKa). D-Isoleucine may be a unique S. cerevisiae (yeast) metabolite.
