Metabolite Identification
Common NameDihydrofolic acid
DescriptionDihydrofolic acid, also known as 7,8-dihydrofolate or H2PTEGLU, belongs to the class of organic compounds known as glutamic acid and derivatives. Glutamic acid and derivatives are compounds containing glutamic acid or a derivative thereof resulting from reaction of glutamic acid at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Since tetrahydrofolate is needed to make both purines and pyrimidines, which are building blocks of DNA and RNA, dihydrofolate reductase is targeted by various drugs to prevent nucleic acid synthesis. Dihydrofolic acid is a drug. Dihydrofolic acid (conjugate base dihydrofolate) (DHF) is a folic acid (vitamin B9) derivative which is converted to tetrahydrofolic acid by dihydrofolate reductase. Dihydrofolic acid is a moderately basic compound (based on its pKa). Click on genes, proteins and metabolites below to link to respective articles. Dihydrofolic acid exists in all eukaryotes, ranging from yeast to humans. Within humans, dihydrofolic acid participates in a number of enzymatic reactions. In particular, dihydrofolic acid can be biosynthesized from tetrahydrofolic acid through its interaction with the enzyme dihydrofolate reductase. In addition, dihydrofolic acid can be converted into folic acid through the action of the enzyme dihydrofolate reductase. In humans, dihydrofolic acid is involved in methotrexate action pathway.

General function:
Involved in tetrahydrofolylpolyglutamate synthase activity
Specific function:
Catalyzes conversion of folates to polyglutamate derivatives allowing concentration of folate compounds in the cell and the intracellular retention of these cofactors, which are important substrates for most of the folate-dependent enzymes that are involved in one-carbon transfer reactions involved in purine, pyrimidine and amino acid synthesis. Unsubstitued reduced folates are the preferred substrates. Metabolizes methotrexate (MTX) to polyglutamates.
