| h English (en) | == Metabolism == The biological activity of folate in the body depends upon [[dihydrofolate reductase]] action in the liver which converts folate into [[tetrahydrofolate]] (THF). This action is rate-limiting in humans leading to elevated blood concentrations of unmetabolized folic acid when consumption from dietary supplements and fortified foods nears or exceeds the U.S. [[Dietary Reference Intake#Parameters|Tolerable Upper Intake Level]] of 1,000 μg per day. |
| h Japanese (ja) | == 代謝 == {{Anchor|Metabolism}} 体内での葉酸の生物学的活性は、葉酸を[[tetrahydrofolate/ja|テトラヒドロ葉酸]]（THF）に変換する肝臓の[[dihydrofolate reductase/ja|ジヒドロ葉酸還元酵素]]の作用に依存する。この作用はヒトでは律速的であるため、サプリメントや強化食品からの摂取量が米国の[[Dietary Reference Intake/ja#Parameters|耐容上限摂取量レベル]]である1日1,000 μgに近いかそれを超えると、代謝されない葉酸の血中濃度が上昇する。 |
