folic acid metabolic process
Definition
Target type: biologicalprocess
The chemical reactions and pathways involving folic acid, pteroylglutamic acid. Folic acid is widely distributed as a member of the vitamin B complex and is essential for the synthesis of purine and pyrimidines. [ISBN:0198506732]
Folic acid, also known as vitamin B9, is a vital nutrient essential for numerous metabolic processes in the body, particularly in cell growth, division, and DNA synthesis. The process of folic acid metabolism involves a series of enzymatic reactions that convert dietary folate into its active form, tetrahydrofolic acid (THF). This process is crucial for various cellular functions, including:
* **DNA synthesis:** THF is a coenzyme for the enzyme thymidylate synthase, which catalyzes the conversion of deoxyuridine monophosphate (dUMP) to deoxythymidine monophosphate (dTMP). dTMP is a crucial building block for DNA, and its synthesis requires THF as a cofactor.
* **Amino acid metabolism:** THF is also involved in the metabolism of several amino acids, including serine, glycine, and methionine. These amino acids are essential for various cellular functions, including protein synthesis and DNA replication.
* **Purine synthesis:** THF is required for the synthesis of purine nucleotides, which are the building blocks of DNA and RNA.
* **Myelination:** Folic acid is crucial for the myelination of nerve fibers, which is the process of forming a protective sheath around nerve cells. This process is essential for the proper functioning of the nervous system.
* **Red blood cell production:** Folic acid is essential for the production of red blood cells, which carry oxygen throughout the body. Deficiency in folic acid can lead to anemia, a condition characterized by low red blood cell count.
The metabolic process of folic acid involves the following key steps:
* **Dietary intake:** Folate is obtained from dietary sources, such as leafy green vegetables, fortified cereals, and liver.
* **Absorption:** Folate is absorbed in the small intestine.
* **Conversion to THF:** Once absorbed, folate is converted to its active form, THF, through a series of enzymatic reactions. This process involves the enzyme dihydrofolate reductase, which reduces dihydrofolate to THF.
* **Utilization:** THF is then utilized in various metabolic reactions, including DNA synthesis, amino acid metabolism, and purine synthesis.
* **Excretion:** Excess folate is excreted in urine.
**Deficiency of folic acid can lead to several health problems, including:**
* **Neural tube defects:** Folic acid deficiency during pregnancy can lead to neural tube defects, such as spina bifida and anencephaly.
* **Anemia:** Folic acid deficiency can lead to megaloblastic anemia, a type of anemia characterized by large, immature red blood cells.
* **Heart disease:** Folate deficiency has been linked to an increased risk of heart disease.
**Supplementation:** Folic acid supplements are available over-the-counter and are recommended for pregnant women and individuals at risk of deficiency.
In summary, folic acid metabolism is a complex process that is essential for various cellular functions. It plays a critical role in DNA synthesis, amino acid metabolism, and the production of red blood cells. Adequate intake of folic acid is crucial for maintaining optimal health.'
