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.
猪血浆中叶酸的主要形式是四氢叶酸。相比之下，在人类和其他已检测的动物物种中，5-甲基四氢叶酸占血浆叶酸的大部分。高亲和力叶酸结合蛋白可能参与调控血浆叶酸的这种分布。
