Natural tshwm sim. Me me ntawm catechol tshwm sim naturally hauv txiv hmab txiv ntoo thiab zaub, nrog rau cov enzyme polyphenol oxidase (tseem hu ua catecholase, lossis catechol oxidase).
Cov zaub mov twg muaj Catechols?
Yog li catechol oxidases muaj nyob txhua qhov chaw - ib pawg enzymes ntau heev. Cov peev txheej uas nquag siv yog txiv tsawb, txiv apples, qos yaj ywm thiab lwm yam vim tias cov no pheej yig thiab yooj yim kom tau txais - tsis tas vim lawv yog qhov muaj zog tshaj plaws ntawm cov enzyme.
Catechol oxidase pom nyob qhov twg?
PPOs tau pom nyob rau hauv ntau lub xov tooj ntawm tes, hauv organelles ( chloroplaststhiab, ntau qhov tseeb, hauv thylakoids, mitochondria, peroxisomes) qhov twg cov enzymes nruj nreem khi rau daim nyias nyias thiab hauv soluble feem ntawm lub cell.
Catechol siv hauv dab tsi?
Catechol (1, 2-dihydroxybenzene) yog siv ntau yam kev siv. Nws yog siv los ua a reagent rau kev yees duab, dyeing plaub, roj hmab thiab yas tsimthiab hauv kev lag luam kws tshuaj (Merck, 1989; Milligan thiab Häggblom, 1998).
Vim li cas cov nroj tsuag muaj catechol?
Catechol oxidase yog li ntawd muaj lub luag haujlwm hauv kev tiv thaiv cov nroj tsuag, pab tiv thaiv cov nroj tsuag puas tawm tsam cov kab mob thiab cov kab mob fungal. Nws tau raug pom zoo tias qhov ntau ntawm catechol oxidase uas tsim los ntawm cov nroj tsuag tuaj yeem cuam tshuam rau nws cov kab mob fungal.
