Ascorbic acidEnzymatic assayAn electrochemical assay of the enzyme alkaline phosphatase (ALP) using ascorbic acid 2-phosphate (AAP) as a new voltammetric substrate has been described in this paper. In the alkaline buffer solution the ALP enzymatic hydrolysis product of AAP was ascorbic acid (AA),...

Using ascorbic acid-2-phosphate trisodium salt (AAP) as a substrate, it can be converted to reduced ascorbic acid (AA) under acid phosphatase (ACP) hydrolysis, resulting in suppression of TMB oxidation. Therefore, an enzyme cascade signal amplification strategy for rapid colorimetric detection of ...
被引量: 4 摘要: The invention relates to a process for preparing ascorbic acid-2-monophosphates (ASMP) from ascorbic acid-2-triphosphates (ASTP); it is characterised in that an ASTP, in particular as an aqueous solution, is dried.收藏...
Ascorbic acid-2-phosphate (AAP) and ascorbic acid (AA) were infiltrated into apple and potato tissue to control browning. Apple tissue absorbed more AAP and AA than potato under similar conditions. AAP hydrolysis by endogenous acid phosphatase (APase) yielded AA which accumulated or became ...

Ascorbic acid 2-phosphateThe performance of ascorbic acid 2-phosphate (AAP), an alternative substrate for alkaline phosphatase (AP), was compared with a widely used 4-aminophenyl phosphate (pAPP). AP is used here as a label in enzyme immunoassay with electrochemical detection. Linear sweep ...
for non-viral drug delivery comprising an ascorbic acid 2-phosphate (AAP) or a polymer thereof (poly(ascorbic acid 2-phosphate)) (pAAP) as an active ingredient, or a method for manufacturing a poly(ascorbic acid 2-phosphate) polymer compound which is a polymer of ascorbic acid 2-phosphate....
By using a systematic analysis, we reveal the mechanism of synergistic protection of N-acetylcysteine (NAC) and ascorbic acid 2-phosphate (AAP) on hMSCs that were under HO-induced oxidative stress. The combined treatment of NAC and AAP (NAC/AAP) reduces reactive oxygen species (ROS) generation...
