D-ribono-1,4-lactone is a five-membered form of ribonolactone having D-configuration. It has a role as a metabolite. It is a ribonolactone and a butan-4-olide. It derives from a D-ribonic acid.
Ribonolactone belongs to the class of organic compounds known as pentoses. These are monosaccharides in which the carbohydrate moiety contains five carbon atoms. Ribonolactone exists as a solid, soluble (in water), and a very weakly acidic compound (based on its pKa). Ribonolactone has been primarily detected in urine. Within the cell, ribonolactone is primarily located in the cytoplasm. Ribonolactone can be biosynthesized from D-ribonic acid.
