StrainBaker's yeast
DescriptionLeukotriene A4, also known as LTA4, belongs to the class of organic compounds known as epoxy fatty acids. These are fatty acids containing an oxirane ring as part of the aliphatic chain. Thus, leukotriene A4 is considered to be an eicosanoid lipid molecule. Leukotriene A4 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
