L-cysteine Base | 52-90-4
Product Description:
Cysteine est albus cristallus vel crystallinus pulveris, solubilis in aqua, leviter odoriferus, in ethanolo solubilis, insolutus organicis menstrualibus ut aether. punctum liquescens 240 ℃ , ratio monoclinica. Cysteine una est ex amino acidorum sulphuris continentis, quod acidum amino non essentiale est.
In organismo, atomus sulphuris methioninae substituitur cum hydroxyli oxygenii atomi serini, et per cystathioninum componitur.
Ex cysteine, glutathione generari potest. glycerolum. Cysteinum est acidum firmum, sed facile cystinum in solutionibus neutris et alkalinis oxiditur.
Efficacia L-cysteini Base:
Cohaeret in corpore, etc.
Efficaciter impedire et injurias femper tractare.
Negat activitatem sulfhydrylasi magni momenti in productione keratin servo cuticulari, et supplementa sulphuris aggregata ad normalem metabolismum cutis conservandam et melanin subiecta melanin productam a pigmento in infimo epidermidis strato moderatur. Est valde idealis medicamine dealbatio naturalis.
Quoties inflammatio vel allergia incidit, sulfydrylase sicut cholphosphatase minuitur, et L-cysteina suppletio actionem sulfydrylasis servare potest et cutis indicia inflammationis et allergia emendare potest.
Effectum habet keratin dissolvendi, unde etiam valet ad hypertrophia keratin morbis cutaneis.
Munus habet vetandi biologicum senescit.
