In this usage, "folate" is just "folic acid" in a non-acidic solution. Health effects[ edit ] Folate is necessary for the production and maintenance of new cellsfor DNA synthesis and RNA synthesis through methylationand for preventing changes to DNAthus for preventing cancer.

Folate deficiency hinders DNA synthesis and cell division, affecting hematopoietic cells and neoplasms the most because of their greater frequency of cell division. RNA transcription and subsequent protein synthesis are less affected by folate deficiency, as the mRNA can be recycled and used again as opposed to DNA synthesis, where a new genomic copy must be created.

Since folate deficiency limits cell division, erythropoiesisproduction of red blood cellsis hindered and leads to megaloblastic anemiawhich is characterized by large, immature red blood cells.

This pathology results from persistently thwarted attempts at normal DNA replication, DNA repair, and cell division, and produces abnormally large red cells called megaloblasts and hypersegmented neutrophils with abundant cytoplasm capable of RNA and protein synthesis, but with clumping and fragmentation of nuclear chromatin.

Some of these large cells, although immature reticulocytesare released early from the marrow in an attempt to compensate for the anemia.
