4-butyrolactone
4-Butyrolactone: One of the FURANS with a carbonyl thereby forming a cyclic lactone. It is an endogenous compound made from gamma-aminobutyrate and is the precursor of gamma-hydroxybutyrate. It is also used as a pharmacological agent and solvent.. tetrahydrofuranone : Any oxolane having an oxo- substituent at any position on the tetrahydrofuran ring.. gamma-butyrolactone : A butan-4-olide that is tetrahydrofuran substituted by an oxo group at position 2. | 2.03 | 1 | 0 | butan-4-olide | metabolite;
