It can be found in the zona reticularis in the adrenal cortex and the stria vascularis in the inner ear. People of African descent were at a higher risk of developing rickets before the advent of vitamin D supplements, because their skin contains higher levels of this substance. In the brain, it causes the distinctive coloration of the locus ceruleus and the substantia nigra. FTP, name this skin and hair pigment whose deficiency can be caused by albinism.
