P-NITROPHENYL BETA-D-LACTOPYRANOSIDE CAS:4419-94-7

P-Nitrophenyl beta-D-lactopyranoside, etiam PNPG notum, compositum est saepe in enzymaticis tentationibus adhibitum ut metiretur activitatem beta-galactosidasi, enzyme in metabolismo carbohydratorum implicatum.PNPG syntheticum subiectum est quod per beta-galactosidasi adhaerere potest, inde in emissione producti flavescentes.Ambitus hydrolysis subiectae quantitatis spectrophotometrice potest metiendo absorpiam producti in determinato necem.Hoc concedit inquisitoribus perpendere actionem et motuum beta-galactosidorum in variis adiunctis, ut in studio enzyme functionis, protegendo enzyme inhibitores vel activatores, vel effectus mutationum in enzyme actuositatis aestimandis.

Application et effectus

Deprehensio actionis beta-galactosidae: PNPG vulgo in pertentatione adhibita ad metiendam actionem beta-galactosidase, enzyme quae hydrolysin lactosi in glucose et galactoso catalysinat.Hydrolysis PNPG per beta-galactosidase moleculum p-nitrophenolum (pNP) emittit, quod spectrophotometrice ob colorem luteum deprehendi potest.

Protegendo pro enzyme inhibitores et activorum: PNPG adhiberi possunt in summo throughput protegendo ad cognoscendas compositiones quae actio beta-galactosidase modulatur.Metiendo ratem PNPG hydrolysim coram diversis compositis testium, investigatores cognoscere possunt inhibitores qui enzyme activitatem minuunt vel activum activum qui enzyme activitatem augent.

Studium enzyme in motu: hydrolysis PNPG per beta-galactosidase sequitur Michaelis-Menten equilibrium, permittens inquisitores ad parametris enzyme magni determinare ut maximam velocitatem reactionis (Vmax) et Michaelis constantis (Km).Haec notitia adiuvat ad intelligendum affinitatem enzyme subiectam et efficientiam catalyticam.

Applicationes biologiae hypotheticae: Beta-galactosidase, quae PNPG cohaeret, vulgo uti notario gene in biologia hypothetica.Substratum PNPG saepe deprehendit et visualisam notarii generum exprimit, dum modo simplex et sensibile est gene expressionem aestimandi in variis systematibus experimentalibus.
