Glucose oxidation in fresh guinea pig cornea.

abstract：:A method for the determination of the specific activity of plasma glycerol is described. Anionic contaminants are first removed from deproteinzed plasma by anionic exchange resins (treated plasma). Glycerol in treated plasma is then quantitatively converted to glycerol-3-phosphate (G3P), which is isolated by column ch...
