Vitamini A ndi vitamini wosungunuka mafuta

Vitamini A Palmitate ndi madzi achikasu mpaka lalanje omwe amagwira ntchito ngati mankhwala. Ili ndi mamolekyulu a C36H60O2 ndi molekyulu yolemera 524.87 g/mol. Pawiri imeneyi ndi insoluble m'madzi koma sungunuka zosiyanasiyana organic solvents. Ndi kuyera kwa ≥ 98%, imadziwika ndi kukhazikika kwake komanso moyo wautali wa alumali wazaka 2-3 ikasungidwa pamalo ozizira, owuma. Vitamini A Palmitate alibe fungo ndipo ali ndi malo osungunuka a 28-29 °C. Amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa chokhala ndi vitamini A wochuluka, omwe amatha kukhala opindulitsa pazinthu monga zowonjezera, zakudya zolimbitsa thupi, ndi zodzoladzola.

Mawu Oyamba

Vitamini A Palmitate, dzina la mankhwala monga retinol acetate, ndiye vitamini woyamba kupezeka. Pali mitundu iwiri ya Vitamini A: imodzi ndi retinol yomwe ndi mtundu woyamba wa VA, imapezeka mu zinyama zokha; wina ndi carotene. Retinol imatha kupangidwa ndi β-carotene yochokera ku zomera. Mkati mwa thupi, pansi pa catalysis ya β-carotene-15 ndi 15'-double oxygenase, β-carotene imasandulika kukhala ratinal yomwe imabwerera ku retinol ndi ntchito ya ratinal reductase. Chifukwa chake β-carotene imatchedwanso vitamini precursor.

Kugwiritsa ntchito

---Zowonjezera Zazakudya:Kugwiritsidwa ntchito kwambiri popanga zakudya zowonjezera zakudya. Zimagwira ntchito yofunika kwambiri pothandizira masomphenya, chitetezo cha mthupi, komanso khungu lathanzi.

---Zakudya Zolimbitsa Thupi:Nthawi zambiri muziwonjezedwa ku zakudya zosiyanasiyana kuti mukhale ndi thanzi labwino. Zitsanzo zodziwika bwino ndi monga mkaka wolimba, chimanga, ndi makanda.

---Zodzoladzola ndi Khungu:Vitamini A, mu mawonekedwe a retinol kapena retinyl palmitate, ndi chinthu chodziwika bwino mu zodzoladzola ndi zinthu zosamalira khungu. Amadziwika chifukwa cha zabwino zake zoletsa kukalamba, monga kuchepetsa mawonekedwe a mizere yabwino, makwinya, ndikulimbikitsa kusintha kwa maselo a khungu.

---Kukonzekera Kwamankhwala:Zochokera ku vitamini A, zomwe zimadziwika kuti retinoids, zimagwiritsidwa ntchito popanga mankhwala. Amagwiritsidwa ntchito pochiza matenda osiyanasiyana a khungu monga ziphuphu zakumaso, psoriasis, photoaging. Retinoids amathandizira kuwongolera kukula kwa maselo ndikulimbikitsa thanzi la khungu.

---Zowonjezera Zakudya za Zinyama:Aphatikizidwe m'zakudya za ziweto kuti zitsimikizire kukula bwino, chitukuko, ndi thanzi labwino la ziweto ndi nkhuku. Zimawathandiza kuti azitha kubereka komanso chitetezo chamthupi.

---Zowonjezera Zaumoyo wa Maso:Nthawi zambiri muphatikizidwe muzaumoyo wamaso, monga retinol kapena mu mawonekedwe a beta-carotene. Zowonjezera izi zimayang'anira kuthandizira thanzi la maso onse ndipo zitha kukhala zopindulitsa kwa anthu omwe ali pachiwopsezo chazaka zokhudzana ndi macular degeneration (AMD) ndi zovuta zina zamaso.
