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 ]
DHA can be formed from cysteine or serine by simple base catalysis without the need for an enzyme, which can happen during cooking and alkaline food preparation processes. It can then alkylate other amino acid residues, such as lysine, forming lysinoalanine cross-links and racemization of the original alanine. The resulting proteins have lower ...
Dehydroascorbic acid, an oxidized form of ascorbic acid; Dehydroacetic acid, a pyrone derivative used as a plasticiser, as a fungicide, as a bactericide, and as a food preservative; Dihydroxyacetone, the active ingredient in sunless or self-tanning skincare products; 9,10-Dihydroanthracene, a form of anthracene whose center-ring carbons have ...
Plasma vitamin C is the most widely applied test for vitamin C status. [8] Adequate levels are defined as near 50 μmol/L. Hypovitaminosis of vitamin C is defined as less than 23 μmol/L, and deficiency as less than 11.4 μmol/L. [ 11 ] For people 20 years of age or above, data from the US 2017–18 National Health and Nutrition Examination ...
Pyuria is the condition of urine containing white blood cells or pus.Defined as the presence of 6-10 or more neutrophils per high power field of unspun, voided mid-stream urine, it can be a sign of a bacterial urinary tract infection.
DHA in breast milk is important for the developing infant. [10] Rates of DHA production in women are 15% higher than in men. [11] DHA is a major fatty acid in brain phospholipids and the retina. Preliminary research has investigated its potential benefit in Alzheimer's disease, [1] [12] and cardiovascular disease, [13] and other disorders. [1]
A basic metabolic panel (BMP) is a blood test consisting of a set of seven or eight biochemical tests and is one of the most common lab tests ordered by health care providers.
