In the second edition, a new chapter is devoted to describe findings about heme uptake, transport, and trafficking of heme synthesis intermediates in mammals. WitrynaThe incorporation of radioactive glycine and δ-aminolevulinic acid into heme in vitro was decreased in vitamin B 6, niacin, pantothenic acid, riboflavin, and thiamine deficiencies, and this became more pronounced with the duration of the deficiencies.
Heme, or haem , is a precursor to hemoglobin, which is necessary to bind oxygen in the bloodstream. Heme is biosynthesized in both the bone marrow and the liver.
