γ-Valerolactone (GVL) is an organic compound with the formula C5H8O2. This colourless liquid is one of the more common lactones. GVL is chiral but is usually used as the racemate. It is readily obtained from cellulosic biomass and is a potential fuel and green solvent. GVL behaves as a prodrug to γ-hydroxyvaleric acid (GHV), a drug with similar effe… Web10. mar 2024 · During intestinal phase, the methylation and sulfation of polyphenols contribute to the enhanced hydrophilicity which helps polyphenols to be further metabolized by organs and excreted to urine.
