WebPolyglutamated folates are poor substrates for folate transport systems and hence restricted to intracellular movement ( Shane and Stokstad, 1975 ), and passive diffusion over intact membranes is negligible due to the negatively charged carboxyl groups on each glutamate unit ( Zhao et al., 2009 ). WebFolic Acid. Folic acid (vitamin B9) has excessive affinity for endogenous folate receptors and thus has been investigated for targeting many types of cancers where folate receptors are highly expressed [51]. ... or degree of polyglutamylation.
