Shanghai Ruifu Chemical Co., Ltd., commercial supply N-(4-Aminobenzoyl)-L-Glutamic Acid (H-4-ABZ-Glu-OH) (CAS: 4271-30-1). It is the intermediate of Folic Acid (CAS: 59-30-3). Folic Acid is a kind of B-vitamin. Folic Acid has various kinds of pharmacological and physiological effects. Folic Acid is involved in amino acid metabolism, purine and pyrimidine synthesis, and is also essential for hematopoiesis and red blood cell generation. In women pregnancy, folate can effectively prevent neural tube defects in the baby. It plays important role in fertility through contributing to spermatogenesis. Folic Acid can also reduce the incidence of heart disease, stroke and cancer. Folate deficiency may lead to various kinds of diseases including glossitis, diarrhea, depression, confusion, anemia, and fetal neural tube defectsand brain defects (during pregnancy).
