  2. Dehydroascorbic acid - Wikipedia

    en.wikipedia.org/wiki/Dehydroascorbic_acid

    Dehydroascorbic acid (DHA) is an oxidized form of ascorbic acid (vitamin C). It is actively imported into the endoplasmic reticulum of cells via glucose transporters. [1] It is trapped therein by reduction back to ascorbic acid by glutathione and other thiols. [2]

    C 6 H 6 O 6 • − + L• + H 2 O + H + → C 6 H 8 O 7 + LH 2 C 6 H 6 O 6 • − + H 2 O + H + → C 6 H 8 O 7 + C 6 H 7 O − 6. Aqueous solutions of dehydroascorbate are unstable, undergoing hydrolysis with a half-life of 5–15 minutes at 37 °C (99 °F). Decomposition products include diketogulonic acid, xylonic acid, threonic acid and ...

  4. Erythorbic acid - Wikipedia

    en.wikipedia.org/wiki/Erythorbic_acid

    One such trial investigated the effects of erythorbic acid on vitamin C metabolism in young women; no effect on vitamin C uptake or clearance from the body was found. [4] A later study found that erythorbic acid is a potent enhancer of nonheme-iron absorption, just like ascorbate. This is thought to be due to it exerting the same iron-reducing ...

    Vitamin C supplements among other dietary supplements at a US drug store. Vitamin C has a definitive role in treating scurvy, which is a disease caused by vitamin C deficiency. Beyond that, a role for vitamin C as prevention or treatment for various diseases is disputed, with reviews often reporting conflicting results.

    The skeletal formula of the antidepressant drug escitalopram, featuring skeletal representations of heteroatoms, a triple bond, phenyl groups and stereochemistry. The skeletal formula, line-angle formula, bond-line formula or shorthand formula of an organic compound is a type of molecular structural formula that serves as a shorthand representation of a molecule's bonding and some details of ...

  7. Calcium metabolism - Wikipedia

    en.wikipedia.org/wiki/Calcium_metabolism

    Calcium regulation in the human body. [6]The plasma ionized calcium concentration is regulated within narrow limits (1.3–1.5 mmol/L). This is achieved by both the parafollicular cells of the thyroid gland, and the parathyroid glands constantly sensing (i.e. measuring) the concentration of calcium ions in the blood flowing through them.

  8. Choline - Wikipedia

    en.wikipedia.org/wiki/Choline

    Choline is a cation with the chemical formula [(CH 3) 3 NCH 2 CH 2 OH] +. [1] [2] [3] Choline forms various salts, such as choline chloride and choline bitartrate.An essential nutrient for animals, it is a structural component of phospholipids and cell membranes.

  9. Calcium supplement - Wikipedia

    en.wikipedia.org/wiki/Calcium_supplement

    Calcium citrate is a better choice for individuals taking medications for gastroesophageal reflux disease, as these medications can reduce stomach acid and impair calcium carbonate absorption. [26] Calcium lactate has similar absorption as calcium carbonate, [42] but is more expensive.
