Qhov sib txawv tseem ceeb ntawm lycopene thiab beta carotene yog tias lycopene yog carotenoid uas tsis muaj cov vitamin A ua haujlwm thaum beta carotene yog carotenoid uas yog lub hauv paus tseem ceeb rau vitamin A.
Carotenoids yog ib pawg ntawm cov xim uas muab cov xim zoo rau cov txiv hmab txiv ntoo thiab zaub, thiab yog li ntawd, pom cov xim daj, txiv kab ntxwv thiab xim liab. Lawv yog cov cog pigments tsuas yog tsim los ntawm ob chav kawm; carotene thiab xanthophylls. Raws li txoj cai, carotenoids yog hydrophobic hydrocarbons. Yog li ntawd, lawv tsis soluble nyob rau hauv dej. Tab sis, lawv yog soluble hauv lipids. Tsis tas li ntawd, carotenoids qhia cov txiaj ntsig sib txawv. Tsis tas li ntawd, lawv pab cov nroj tsuag rau photosynthesis.
Tsis tas li ntawd, lawv muaj cov tshuaj tua kab mob antioxidant, tshuaj tiv thaiv kab mob, thiab tshuaj tiv thaiv kab mob. Ntxiv mus, carotenoids yog nrov hauv kev tiv thaiv kab mob plawv thiab. Ntau cov txiv hmab txiv ntoo thiab zaub xws li carrots, yam, qos yaj ywm qab zib, papaya, dib liab, cantaloupe, mangos, spinach, kale, txiv lws suav, tswb peppers thiab txiv kab ntxwv yog qhov zoo ntawm carotenoids. Qee qhov kev kawm carotenoids feem ntau yog beta-carotene, lycopene, lutein, thiab zeaxanthin.
Lycopene yog dab tsi?
Lycopene yog ib qho ntawm cov carotenoids nrov. Nws yog xim liab xim cog xim uas ua raws li qhov tseem ceeb nruab nrab hauv biosynthesis ntawm ntau carotenoids nrog rau beta-carotene thiab xanthophyll. Tab sis, tsis zoo li beta carotene, lycopene tsis muaj cov tshuaj vitamin A.
Structurally, lycopene yog ib txoj hlua C ntev uas muaj 13 ob daim ntawv cog lus. Tsis tas li ntawd, nws yog hydrocarbon. Tab sis, nws tsis muaj lub nplhaib beta-ionone, uas muaj nyob hauv beta carotene. Txawm li cas los xij, lycopene thiab beta-carotene muaj cov qauv molecular zoo sib xws (C40H56) thiab molecular mass (536 g / mol).
Saib cov peev txheej ntawm lycopene, lycopene muaj cov txiv lws suav. Tsis tas li ntawm cov txiv lws suav, cov qib lycopene muaj ntau cov txiv hmab txiv ntoo thiab zaub xws li lub caij nplooj zeeg txiv ntseej, gac, txiv kab ntxwv, liab txiv kab ntxwv, liab guava, papaya, seabuckthorn, wolfberry, thiab lwm yam.
Daim duab 01: Lycopene hauv Txiv lws suav
Txij li thaum, lycopene yog qhov tseem ceeb nruab nrab ntawm kev tsim beta-carotene, qib ntawm lycopene nce mus thaum beta carotene synthesis nres. Nws yog pom tseeb nyob rau hauv txiv lws suav. Thaum cov txiv lws suav loj tuaj, cov synthesis ntawm beta carotene txo qis thiab cov txiv lws suav yuav liab tag nrho vim muaj cov lycopene.
Y Beta Carotene yog dab tsi?
Beta carotene yog ib qho ntawm cov carotenoids uas muaj cov vitamin A ua haujlwm. Hauv cov lus yooj yooj yim, beta carotene yog carotenoid uas tuaj yeem hloov tau yooj yim rau hauv vitamin A. Li no; Nws yog ib qho tseem ceeb rau kev noj qab haus huv qhov muag thiab tawv nqaij. Tsis tas li ntawd, nws feem ntau yog xim txiv kab ntxwv xim xim. Qhov tseeb, beta carotene yog cov nroj tsuag xim uas muab cov zaub ntug hauv paus nws cov xim txiv kab ntxwv.
Beta carotene muaj nyob hauv ntau hom txiv hmab txiv ntoo thiab zaub. Xav txog cov txiaj ntsig kev noj qab haus huv, beta carotene yog lub zog antioxidant. Nws muaj peev xwm ua kom puas tsuaj rau cov dawb radicals uas ua rau peb cov hlwb puas. Tsis tas li ntawd, beta carotene tuaj yeem txo qhov kev pheej hmoo ntawm kab mob plawv, mob stroke, macular degeneration, thiab lwm yam kab mob ntsig txog hnub nyoog.
Daim duab 02: Beta Carotene
zoo ib yam li lycopene, qhov hnyav molecular ntawm beta carotene yog 536 g / mol thiab cov mis molecular yog C 40H 56. Txawm li cas los xij, tsis zoo li lycopene, C saw ntawm beta carotene tsuas muaj 11 ob daim ntawv cog lus xwb.
Dab tsi zoo sib xws ntawm Lycopene thiab Beta Carotene?
- Lycopene thiab beta carotene yog phytochemicals uas yog carotenoids.
- Lawv yog tetraterpene
- Ntxiv mus, lawv yog hydrophobic hydrocarbons.
- Yog li, ob leeg yog insoluble hauv dej, tab sis soluble hauv lipids.
- Kuj, ob qho tib si lawv cov xim yog daj, txiv kab ntxwv thiab liab.
- Tsis tas li ntawd, lawv muaj qhov hnyav molecular zoo tib yam thiab cov mis molecular.
- Lawv muaj cov hlua C ntev ntev teem los ntawm yim lub isoprene nrog plaub chav nyob sib ntsib.
- Tsis tas li, ob leeg nqus lub teeb hauv lub teeb xiav.
- Dhau li ntawd, ob leeg yog cov tshuaj antioxidants zoo heev.
- Vim li no, ob qho tib si tuaj yeem txo qhov kev pheej hmoo ntawm kab mob plawv.
Qhov txawv ntawm Lycopene thiab Beta Carotene yog dab tsi?
Lycopene thiab beta carotene yog ob carotenoids. Lycopene tsis muaj pro-vitamin A kev ua, thiab li no, tsis tuaj yeem hloov nws mus rau hauv vitamin A. Ntawm qhov tod tes, beta carotene muaj pro-vitamin A kev ua, thiab yog li ntawd, tuaj yeem hloov nws mus rau hauv vitamin A. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm lycopene thiab beta carotene.
Tsis tas li ntawd, ib qho sib txawv ntawm lycopene thiab beta carotene yog tias lycopene feem ntau yog xim liab xim thaum beta carotene feem ntau yog xim txiv kab ntxwv xim. Ntxiv mus, ob qho tib si lycopene thiab beta carotene yog hydrocarbons thiab muaj cov mis mos molecular zoo tib yam thiab qhov hnyav molecular. Txawm li cas los xij, cov saw hlau carbon ntawm lycopene muaj 13 ob daim ntawv cog lus thaum cov saw hlau ntawm beta carotene muaj 11 ob daim ntawv cog lus. Li no, cov qauv, qhov no yog qhov sib txawv ntawm lycopene thiab beta carotene.
Cov duab hauv qab no ntawm qhov sib txawv ntawm lycopene thiab beta carotene muab cov ntsiab lus ntxiv txog qhov sib txawv no.
Summary – Lycopene vs Beta Carotene
Lycopene thiab beta carotene yog ob carotenoids. Ob leeg yog cov muaj peev xwm ntuj antioxidants thiab cov tshuaj tiv thaiv kab mob. Txawm li cas los xij, vim tsis muaj beta nplhaib hauv lycopene, nws tsis muaj cov vitamin A ua haujlwm. Ntawm qhov tod tes, beta carotene muaj pro-vitamin A kev ua, thiab nws yog lub ntsiab precursor ntawm vitamin A. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm lycopene thiab beta carotene.
Tsis tas li ntawd, lycopene muaj ntau hauv txiv lws suav thaum beta carotene muaj ntau hauv carrots. Yog li, qhov no qhia txog qhov sib txawv ntawm lycopene thiab beta carotene.
