Tento postupn\u00fd pokles nazna\u010duje jasn\u00e9, s vekom s\u00favisiace zn\u00ed\u017eenie dostupnosti tohto peptid.<\/p>\n
Na molekul\u00e1rnej \u00farovni jedn\u00fdm z hlavn\u00fdch faktorov je enzymatick\u00e1 degrad\u00e1cia. GHK je n\u00e1chyln\u00fd na degrad\u00e1ciu enz\u00fdmami, ako s\u00fa karboxypeptid\u00e1zy, ktor\u00e9 s\u00fa zodpovedn\u00e9 za rozklad mal\u00fdch peptidov na men\u0161ie fragmenty. V priebehu \u010dasu neust\u00e1la enzymatick\u00e1 aktivita zni\u017euje stabilitu aj hladinu cirkuluj\u00faceho GHK. V d\u00f4sledku toho je pre telo \u0165a\u017e\u0161ie udr\u017eiava\u0165 stabiln\u00e9 koncentr\u00e1cie, najm\u00e4 v tkaniv\u00e1ch, ktor\u00e9 vy\u017eaduj\u00fa neust\u00e1lu regener\u00e1ciu, ako je starn\u00faca poko\u017eka alebo chronick\u00e9 rany.<\/p>\n
\u010eal\u0161ou d\u00f4le\u017eitou pr\u00ed\u010dinou je zv\u00fd\u0161en\u00e1 spotreba po\u010das procesov hojenia a reakci\u00ed na stres. GHK sa uvo\u013e\u0148uje zo \u0161truktur\u00e1lnych prote\u00ednov extracelul\u00e1rnej matrix, vr\u00e1tane kolag\u00e9nu a SPARC, najm\u00e4 v situ\u00e1ci\u00e1ch po\u0161kodenia alebo prestavby tkaniva. Po uvo\u013enen\u00ed p\u00f4sob\u00ed ako sign\u00e1lna molekula, ktor\u00e1 aktivuje ozdravn\u00e9 procesy. Tie zah\u0155\u0148aj\u00fa produkciu kolag\u00e9nu, tvorbu nov\u00fdch krvn\u00fdch ciev (angiogen\u00e9zu), rast nervov a n\u00e1bor imunitn\u00fdch buniek. S prib\u00fadaj\u00facim vekom telo hromad\u00ed viac po\u0161koden\u00ed a regenera\u010dn\u00e9 procesy sa spoma\u013euj\u00fa. To zvy\u0161uje dopyt po sign\u00e1loch na opravu, \u010do znamen\u00e1, \u017ee dostupn\u00fd GHK sa \u010dastej\u0161ie vyu\u017e\u00edva a nie je plne dop\u013a\u0148an\u00fd.<\/p>\n
Okrem toho je v\u00fdznamn\u00fd prirodzen\u00fd pokles regenera\u010dn\u00fdch schopnost\u00ed. U mlad\u0161\u00edch os\u00f4b s\u00fa opravn\u00e9 syst\u00e9my \u00fa\u010dinnej\u0161ie a hladiny GHK zost\u00e1vaj\u00fa vy\u0161\u0161ie, \u010d\u00edm podporuj\u00fa procesy, ako je aktivita fibroblastov, funkcia kme\u0148ov\u00fdch buniek a obnova extracelul\u00e1rnej matrix. S prib\u00fadaj\u00facim vekom sa fibroblasty st\u00e1vaj\u00fa menej akt\u00edvnymi, aktivita kme\u0148ov\u00fdch buniek kles\u00e1 a celkov\u00e1 obnova tkan\u00edv sa spoma\u013euje. To vedie k zn\u00ed\u017eenej produkcii a menej efekt\u00edvnej recykl\u00e1cii GHK v tele.<\/p>\n
Zmeny v expresii g\u00e9nov a bunkovej signaliz\u00e1cii m\u00f4\u017eu ma\u0165 tie\u017e v\u00fdznam. Je zn\u00e1me, \u017ee GHK ovplyv\u0148uje mnoh\u00e9 g\u00e9ny spojen\u00e9 s opravou, antioxida\u010dnou ochranou a kontrolou z\u00e1palu. S prib\u00fadaj\u00facim vekom doch\u00e1dza v tele k zmen\u00e1m v g\u00e9novej aktivite, \u010do m\u00f4\u017ee sp\u00f4sobi\u0165 oslabenie dr\u00e1h zodpovedn\u00fdch za udr\u017eiavanie \u00farovne GHK \u2013 \u010di u\u017e prostredn\u00edctvom jeho produkcie, uvo\u013e\u0148ovania alebo stability \u2013 \u010do \u010falej prispieva k jeho poklesu.<\/p>\n
