It can be synthesized from tryptophan via a kynurenine intermediate, and mutations in SLC6A19 decreases the levels of this vitamin in the bloodstream; that mutation causes Hartnup's disease.
This molecule's binding to the G109A receptor on adipocytes decreases the flux of free fatty acids to the liver and increases HDL levels, though it is often given with laropiprant to reduce flushing. It can be synthesized from tryptophan via a kynurenine intermediate, and mutations in SLC6A19 decreases the levels of this vitamin in the bloodstream; that mutation causes Hartnup's disease. Consisting of a carboxyl group bound to pyridine, a deficiency of this vitamin, which is the precursor for the electron carriers NAD and NADP, causes a disease with diarrhea, dermatosis, and dementia, known as pellagra. For 10 points, name this substance also known as Vitamin B3.
