Chemical Information
FooDB Namealpha-Lactose
DescriptionAlpha-Lactose, also known as anhydrous lactose or tablettose, belongs to the class of organic compounds known as o-glycosyl compounds. These are glycoside in which a sugar group is bonded through one carbon to another group via a O-glycosidic bond. Alpha-Lactose is an extremely weak basic (essentially neutral) compound (based on its pKa). Alpha-Lactose exists in all living organisms, ranging from bacteria to humans. Alpha-Lactose is found, on average, in the highest concentration within milk (cow). Alpha-Lactose has also been detected, but not quantified in, several different foods, such as cow milks, cow milks, cow milks, and cow milks. This could make Alpha-lactose a potential biomarker for the consumption of these foods. Alpha-Lactose is a potentially toxic compound.
