Mechanism of ActionMechanism of ActionFolates are deconjugated in the cells of
intestinal walls into its monoglutamate form.
Mechanism of ActionMechanism of Action
Folates function as carbon donors in the synthesis of serine.
Mechanism of ActionMechanism of Action
Folates also play an important role in the synthesis of purines, pyrimidine bases & in the synthesis of tRNA.
Mechanism of ActionMechanism of Action
Folates also serve as methyl donors to create methylcobalamin, which is used for remethylation of homocysteine to methionine.
Methylcobalamin
Studies on Folic AcidStudies on Folic Acid
Blount et al (1997) recently showed that folate deficiency can cause a massive incorporation of uracil into human DNA, hence leading to chromosome breaks.
Another study by Kim et al (1997) suggested that folate deficiency induces DNA strand breaks and hypomethylation within the p53 gene.
Several other studies have also shown that Folic Acid deficiency can also cause Neural Tube Defects, Cancer, Alzheimer’s disease and Anemia.
ConclusionConclusion
Prevents Serious Birth Defects
Prevents Cancer
Prevents Alzheimer’s
Prevents Heart Disease & Stroke
Future DirectionFuture Direction
Folic acid can improve endothelial function
Folic acid plays an important role in production of normal red blood cells.
