Pantothenic acid (vitamin B 5) is a B vitamin and an essential nutrient. [6] All animals need pantothenic acid in order to synthesize coenzyme A (CoA), which is essential for cellular energy production and for the synthesis and degradation of proteins, carbohydrates, and fats. [6] [7] Pantothenic acid is the combination of pantoic acid and β ...
Folic acid, which is the synthetic form of the vitamin folate, is critical both in pre- and peri-conception. [7] Deficiencies in folic acid may cause neural tube defects (NTDs). Women who had 0.4 mg of folic acid in their systems due to supplementing 3 months before childbirth significantly reduced the risk of NTDs. [29]
Due to tolerance challenges, the prenatal vitamin industry has developed a multitude of dosage forms to meet the needs and tolerances of expecting mothers. The most common form of prenatal vitamin is the compressed tablet which is available through all channels and at various quality levels.
Pantothenic acid is involved in the oxidation of fatty acids and carbohydrates. Coenzyme A, which can be synthesised from pantothenic acid, is involved in the synthesis of amino acids, fatty acids, ketone bodies, cholesterol, [15] [better source needed] phospholipids, steroid hormones, neurotransmitters (such as acetylcholine), and antibodies. [16]
Additional energy is required during pregnancy due to the expansion of maternal tissues and stored to support fetal development. In the first trimester (blastogenesis and early embryonic stages), the mother experiences a minimal weight gain (approximately 0.5-2 kilograms), while the embryo weighs only 6 grams.
Pantothenate kinase (EC 2.7.1.33, PanK; CoaA) is the first enzyme in the Coenzyme A (CoA) biosynthetic pathway. It phosphorylates pantothenate (vitamin B 5) to form 4'-phosphopantothenate at the expense of a molecule of adenosine triphosphate ().
Panthenol (also called pantothenol) is the alcohol analog of pantothenic acid (vitamin B 5), and is thus a provitamin of B 5. In organisms, it is quickly oxidized to pantothenic acid. It is a viscous transparent liquid at room temperature. Panthenol is used in pharmaceutical and children's products as a moisturizer and to hasten wound healing.
The SMVT is a transporter for pantothenic acid (vitamin B5) and biotin (vitamin B7) at the blood–brain barrier. [8] It is also a transporter for lipoic acid [9] and iodide. Transport of these nutrients is competitive [10] and a surplus of a given nutrient may saturate the transporter and prevent the uptake of other nutrients.
