Metabolite Identification
Common Namealpha-Santalyl acetate
DescriptionD-Galactose, also known as D-galactopyranose, belongs to the class of organic compounds known as hexoses. These are monosaccharides in which the sugar unit is a is a six-carbon containing moeity. A galactopyranose having D-configuration. D-Galactose is an extremely weak basic (essentially neutral) compound (based on its pKa). Within humans, D-galactose participates in a number of enzymatic reactions. In particular, D-galactose and sorbitol can be converted into melibiitol through its interaction with the enzyme Alpha-galactosidase a. In addition, D-galactose and D-mannose can be converted into epimelibiose through its interaction with the enzyme Alpha-galactosidase a. In humans, D-galactose is involved in galactose metabolism. Outside of the human body, D-Galactose is found, on average, in the highest concentration within a few different foods, such as taro, honey, and dulce de leches and in a lower concentration in cloves, baby foods, and apples. D-Galactose has also been detected, but not quantified in, several different foods, such as chanterelles, rose hips, horseradish tree, abiyuchs, and corn grits. This could make D-galactose a potential biomarker for the consumption of these foods.
