Function & application of N-Acetyl-L-Cysteine (Ac-Cys-OH; NAC) (CAS: 616-91-1) pulveris
1. N-Acetyl-L-Cysteine, etiam N-Acetylcysteinum seu Acetylcysteinum (NAC), medicamentum pharmaceuticum et supplementum nutritionis adhibitum est imprimis ut agens mucolyticum et in administratione paracetamoli (acetaminophen) dosi.Alii usus repletionem sulfate in condicionibus includunt, ut autismus, ubi cysteinum et amino acida sulphure affine possunt levari.
2. N-Acetyl-L-Cysteinum est cysteinum derivativum ubi globus acetyl atomo nitrogeni adnectitur.Compositum hoc venditum est sicut supplementum puritatis antioxidant et iecoris tuendi effectus vulgo affirmant.Utitur ad tussim medicina, quia vincula muci frangit et liquefacit, et ad tussim facilius ascendit.Est etiam haec actio solvendi vincula dissolvendi, quae in extenuando enormiter spissam muci cystici et fibrosi pulmonis utilem facit.
3. Acetylcysteinum est agens mucolyticum cum effectu mucolytico valido.Globus sulfhydrylus in moleculo comprehensus vinculum glycoprotein polypeptidis in sputum catenam disulfitum frangere potest, inde viscositatem sputum reducens, et sputum liquidum faciens et ad tussim facile ascendit.Hoc productum etiam fibras DNA in sputo purulento frangere potest, ut album non solum sputum glutinosum dissolvere possit, sed etiam sputum purulentum.Aegris, quorum exspectatores generales inefficaces sunt, hoc productum potest adhuc efficax esse.
4. Medicina ad phlegma dissolvendum adhibetur.Usus est in investigationibus diameticis et medicina pro antidoto pro phlegmate et acetaminophen veneficii.Biochemical reagens, medicina, hoc productum ut excrementum adhibetur, dixit pituitam facile purgare.
5. Communia lateris effectus nauseam et vomitum per os includunt. Utraque cutis interdum rubra et scabies cum utraque specie fieri potest.Genus anaphylaxis non-immune etiam fieri potest.Videtur in graviditate tutus.Nam paracetamolum dosis, augendo gradum glutathionis, antioxidant qui potest corrumpere toxici naufragii fructus paracetamoli operatur.Haustus, mucolytice, muci crassitiem decrescens agit.
6. Acetylcysteine initio anno 1960 patente et in usum medicinae anno 1968 venit. Est in indice Medicamentorum Mundi Salus Organizatio Essentialium, quae tutissima et efficacissima medicamenta in systemate sanitatis requiruntur.Praesto est medicamentum genericum et vilis est.
7. N-Acetyl-L-Cysteine forma est acetyllata L-cysteini quae efficacius absorbetur et adhibetur.Prodest etiam contra virus antioxidum.N-Acetyl-l-Cysteine hepatis custodientis adhibitus est et muci pulmonis et bronchialis diducere.
8. N-Acetyl-L-Cysteine graduum glutathionis in cellis potest boost.
9. N-Acetyl-L-Cysteinum est amino acidum conditionaliter essentiale, unum e tribus tantum acidis sulphuris amino contentis, aliis taurinis (quod ex L-cysteine produci potest) et L-methioninum ex quo L-cysteinum potest. produci in corpore per multi- gradatim processum.
10. N-Acetyl-L-Cysteine antioxidante agere potest, morbos hepatis impedire, adiuvare potest ut singulas diametris pilorum sumptis regulariter exsistentium crebrescat.
11. Applicatio in campis medicis Ut agentis respiratorii ratio, medicina adhiberi potest ad tympana pituitae solvenda.BRONCHITIS mederi potest.praeterea N-Acetyl-L-Cysteine antidoto adhiberi potest cum acetaminophen veneficii.
12. Applicatio in campis medicamine N-Acetyl-L-Cysteine magnam vim habet in purgando oxygenii liberas radicales et alias oxydatum et retardationem processus senescentis, etiam melaninum perturbare potest, et prodest ad pelliculas in cute tollendas.
13. Applicatio in feeds animalis N-Acetyl-L-Cysteine adhiberi potest ut cibarium additivum.
Medicamina maxime adhibentur ad pulchritudinem aquae, perm fluidum, sol-probatio cutis cura cremor.Munus ne biologicum tincidunt velit.N-Acetyl-l-Cysteine efficaciter impedire et injuriam femper tractare potest.N-acetyl Cysteine melanin ipsam cutem tollere potest, ipsam cutem mutare, cutis albescere naturalis fit. Est quoddam specimen naturale albescentes uterentur.
15. Cibus Elogium.In pane, ad formationem glutinis promovendam et fermentum fovendam, fingunt, ne senescit.Adhibetur in succis naturalibus ne vitaminum C ab oxidizing ac ne succi brunneis convertantur.
