Tib neeg lub cev tsis tuaj yeem ua kelycopenethiab yuav tsum tau txais nws los ntawm cov zaub mov exogenous. Tus nqi ntawm lycopene nyob rau hauv txhua yam zaub thiab txiv hmab txiv ntoo sib txawv, nrog txiv lws suav muaj qib siab tshaj plaws.
Cov ntsiab lus lycopene hauv cov zaub thiab txiv hmab txiv ntoo (mg / kg) | |||||
Txiv lws suav | Guava | Grapefruit | Txiv lws suav | Papaya | Plum |
50 ~120 | 50~60 | 30~40 | 20~70 | 20~50 | 0.05~0.1 |
Tom qab nqus tau, lycopene tau dav dav hauv cov ntshav, testis, prostate, lub mis, zes qe menyuam thiab lwm cov ntaub so ntswg thiab kabmob. Ntawm lawv, lycopene muaj ntau dua hauv cov ntshav, qog adrenal thiab cov qog ntshav.
Biosynthesis ntawm Lycopene
Thaum lub sij hawm txiv hmab txiv ntoo loj hlob thiab kev loj hlob, lub synthesis ntawm lycopene yog manifested nyob rau hauv ob theem:
Ua ntej, thaum lub sij hawm discoloration thiab maturity theem, cov xim ntawm cov txiv hmab txiv ntoo hloov heev, thiab lycopene pib synthesize thiab accumulates sai heev kom txog thaum nws mus txog rau lub siab tshaj plaws cov ntsiab lus. Ua ntej no, cov ntsiab lus lycopene hauv cov txiv hmab txiv ntoo yog tsawg heev (xws li txiv lws suav thiab txiv lws suav).
Qhov thib ob, lycopene pib maj mam sib xyaw ua ke hauv cov txiv hmab txiv ntoo hluas, thiab yog synthesized loj nyob rau hauv lub mature theem thiab accumulates sai nyob rau hauv cov txiv hmab txiv ntoo (xws li liab navel txiv kab ntxwv). Qhov no qhia tau hais tias qhov sib txawv ntawm cov theem kev loj hlob ntawm cov nroj tsuag sib txawv thiab cov ntaub so ntswg thiab cov kab mob tshwj xeeb tuaj yeem ua rau muaj qhov sib txawv ntawm lycopene synthesis tus nqi.
Kev faib tawm thiab nqus ntawm Lycopene
Cov lycopene hauv cov kua txiv lws suav uas muaj cua sov tau yooj yim nqus tau yooj yim dua li qhov tsis tau kho, nrog rau cov ntshav qab zib siab siab ntawm 24-48 h thiab ib nrab-lub neej ntawm 2-3 hnub. Nrog rau kev noj zaub mov ntau ntxiv, cov ntshav siab ntawm lycopene nce ntxiv, tab sis kev sib raug zoo tsis yog kab, thiab cis-daim ntawv (xws li 9-cis, 13-cis) yog nqus tau yooj yim dua li cov trans. - daim ntawv.
Lycopene yog ib qho lipid uas yuav tsum tau yaj hauv cov roj rau kev nqus thiab thauj, yog li qhov muaj qee cov roj yuav tsum tau ua kom nws cov bioavailability. Yog li, qhov sib ntxiv ntawm lycopene rau oleoresin rau kev tso tawm cov nyhuv tuaj yeem ua rau cov ntsiab lus ntawm qhov ncauj mucosal ntau dua piv nrog kev noj cov kua txiv lws suav. Hauv vivo, nws nkag mus rau hauv chylomicrons los ntawm cov kab mob hauv plab hnyuv me, thiab tom qab ntawd tso tawm mus rau hauv cov qog ntshav thiab cov ntshav, uas nws thauj los ntawm cov lipoprotein tsawg ntom ntom ua cov cab kuj.
