Identification
YMDB IDYMDB00353
NameOrnithine
SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
DescriptionOrnithine, also known as (S)-ornithine, belongs to the class of organic compounds known as l-alpha-amino acids. These are alpha amino acids which have the L-configuration of the alpha-carbon atom. Ornithine is a very strong basic compound (based on its pKa). Ornithine exists in all living species, ranging from bacteria to humans. Ornithine is a potentially toxic compound.
