The Effects of Gonadal Hormones and Contraceptive Steroids on Tryptophan Metabolism

  • D. P. Rose


The pathway by which tryptophan is metabolized to yield nicotinic acid ribonucleotide has been the subject of considerable interest in recent years. Abnormal urinary excretion of metabolites of this pathway in vitamin B6 deficiency has led to the extensive use of a tryptophan load test for the study of pyridoxine requirements in man (1–3).
