개요
Allantoin is a product of purine and uric acid metabolism. It is formed through oxidation of uric acid by urate oxidase in most mammals but is formed only through non-enzymatic oxidation by free radicals in humans. Urinary levels of allantoin are increased prior to the onset of Alzheimer’s disease symptoms in mice expressing mutations in amyloid precursor protein and tau (APP/tau) but not during the early/middle stage of the disease, indicating its potential use as a biomarker for predicting Alzheimer’s disease onset. Due to the formation of allantoin by free radicals in humans, increased urinary levels are a potential biomarker for oxidative stress status.화학적 성질
White Solid용도
allantoin is a botanical extract said to be healing, calming, and soothing, it can also help protect the skin from harmful external factors (e.g., wind burn). It is considered an excellent temporary anti-irritant and is believed to stimulate new tissue growth, helping heal damaged skin. Allantoin is appropriate for sensitive, irritated, and acne skins. Derived from the comfrey root, it is considered non-allergenic.정의
ChEBI: An imidazolidine-2,4-dione that is 5-aminohydantoin in which a carbamoyl group is attached to the exocyclic nitrogen.일반 설명
Allantoin, the final catabolic product of purines in mammals, is a highly polar and amphoteric substance. Allantoin is mainly used for skin protection as the drug promotes cell proliferation and wound healing.Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
