描述
1-rhamnono-1,4-lactone is a member of the class of compounds known as gamma butyrolactones. Gamma butyrolactones are compounds containing a gamma butyrolactone moiety, which consists of an aliphatic five-member ring with four carbon atoms, one oxygen atom, and bears a ketone group on the carbon adjacent to the oxygen atom. 1-rhamnono-1,4-lactone is soluble (in water) and a very weakly acidic compound (based on its pKa). 1-rhamnono-1,4-lactone can be found in rice, which makes 1-rhamnono-1,4-lactone a potential biomarker for the consumption of this food product.
