Heme synthesis in vitamin B6 and pantothenic acid deficiencies.
Shemin and coworkers (14) showed that the a-carbon and nitrogen atoms of glycine were precursors of specific atoms of the heme molecule. This was substantiated by Muir and Neuberger (5, 6). Other carbon atoms were shown to come from acetate (5-7) or succinate (8). The nature of the intermediate precursors synthesized from these metabolites remained unknown until the structure for urinary porpho...

متن کاملSynthesis and properties of pantothenic acid monophosphates.
Although it appears most probable that coenzyme A is a phosphate derivative of pantothenic acid (2), little information is available as to the position or nature of the phosphate linkage in the molecule. It became of interest in this connection to examine the properties of simple phosphate derivatives of pantothenic acid, and for this purpose efforts were directed toward the preparation of the ...
