D-(+)-Glucono-1,5-lactone CAS 90-80-2
Gluconolactone ndi ester yomwe imakhala yopanda madzi pakati pa gulu la carboxyl la gluconic acid ndi gulu la intramolecular hydroxyl, ndi ester yomwe imakhala yopanda madzi pakati pa gulu la hydroxyl pa lachisanu (δ) atomu ya carbon, yotchedwa gluconol-delt-lactone; Ester yotaya madzi m'thupi ndi gulu la hydroxyl pa atomu ya kaboni yachinayi (gamma-position) imatchedwa glucono-gamma-lactone. A kristalo. Ili ndi kukoma kosiyana ndi gluconic acid.
