Interspecies differences in folate metabolism.
The primary form of folate in the plasma of pigs is tetrahydrofolate. In contrast, 5-methyl-tetrahydrofolate comprises most of all of the plasma folate in humans and other animal species examined. High-affinity folate-binding proteins may be involved in governing this distribution of plasma folates.
