Folates combine three molecules : pretidine & para-aminobenzoic acid (PABA) & glutamate. They were discovered around 1940 and first isolated from spinach leaves. The term folate is derived from the latin word folium.
The malaria parasite has a unique feature of being able to salvage exogenous folate derivatives and/or synthesize them de novo. Due to its high rate of replication, the parasite has a high demand for folates. Folate metabolism is the target of several antimalarials.
