Abstract
6-Carboxypterin was photolyzed at 350 mm in aqueous acid and alkaline solut ions at room temperature. The photochemical reaction was followed by UV-Vis spectrophotometry, thin layer chromatography (TLC) and HPLC. Changes in th e absorption spectrum of the irradiated solution, TLC and HPLC, show the fo rmation of pterin as one of the photoproducts, The quantum yields of 6-carb oxypterin disappearance and of pterin formation were shown to be pH and oxy gen dependent.
