Abstract
Summary
3,4-dihydroxyanthranilic acid was not converted to quinolinic acid or nicotinic acid by rat or hog liver preparations. Spectrophotometric evidence indicates that this compound is not the transient intermediate formed in the conversion of 3-hydroxyanthranilic to quinolinic acid by liver enzymes. It was not utilized by Xantho-monas pruni for growth, or by the rat for growth or formation of urinary nicotinic acid or quinolinic acid.
