Synthesis of pteroylpolyglutamates in rat liver during regeneration after partial hepatectomy.

The liver content of higher polyglutamate forms of folic acid, which in partially hepatectomized rats is markedly lower as compared with sham operated animals, is normalized by the vitamin administration. The greater availability of folic acid and consequently of the tetrahydrofolates, promotes the synthesis of actual coenzymic forms; so their content, in regenerating liver, is maintained at normal values in spite of a higher requirement caused by the exaltation of biosynthetic processes.
