The metabolism of some folates in the rat.
1. A number of folates labelles with 14-C were administered orally to rats, at various doses, and urinary, faecal and hepatic folates examined. 2. 10-Formylpteroylmonoglutamic acid ( 10CHO--PGA) entered the folate pool very slowly, and is thought to be relatively ineffective in nutrition. 3. 10-Formyl[2-14-C]tetrahydrofolic acid (10CHO--[2-14-C]THF) entered the folate pool very rapidly. 5-Methy...
متن کاملHigh-molecular-weight folates of rat liver.
PATRICIA A. BARFORD, JOHN A. BLAIR and FREDERICK J. STAFF Department of Chemistry, University of Aston in Birmingham, Gosta Greem, Birmingham B4 7ET, U.K. It has been frequently claimed that polyglutamate forms of folates are found in animals (Noronha & Silverman, 1962; Shin et al., 1972; Brown et al., 1974) on the basis of column chromatography of these folates and chromatography of 'authentic...
متن کاملPurine biosynthesis in the domain Archaea without folates or modified folates.
The established pathway for the last two steps in purine biosynthesis, the conversion of 5-aminoimidazole-4-carboxamide ribonucleotide (ZMP) to IMP, is known to utilize 10-formyl-tetrahydrofolate as the required C1 donor cofactor. The biosynthetic conversion of ZMP to IMP in three members of the domain Archaea, Methanobacterium thermoautotrophicum deltaH, M. thermoautotrophicum Marburg, and Sul...
