Khoom Piav Qhia
Retinal Hmoov, uas yog cov khoom sib xyaw ua ke kom rov qab ua kom zoo dua qub, yog tsim los ntawm oxidative cleavage ntawm beta-carotene. Txo cov yielding Retinol, thiab oxidation yields retinal. Retinal is a co-factor of rhodopsin. Hauv cov kab muag, 11-NPIS retinal thiab opsin form duab kos duab. Tom qab nqus tau lub teeb, 11-Cis recinal isomerizes rau hauv txhua qhov kev hloov pauv ntawm cov kev sib xyaw ua ke rau lub hlwb, yog li tsim lub zeem muag.
Retinal yog lub teeb liab tseem ceeb transduction molecule hauv qhov kev loj hlob ntawm qhov muag thiab nws si ntau txoj kev loj hlob thiab qhov tseem ceeb hauv kev txhim kho ntawm vertebrates. Retinal nyob rau hauv lub retina, no 11-cis-retinaldehyde yog tsim los ntawm enzymatic cov tshuaj tiv thaiv los ntawm txhua-trans retinaldehyde lossis 11-CIS-RETINOL (ib qho tshiab vitinol (ib qho tshiab vitamol (ib qho tshiab vitamol (ib qho tshiab vitinol). Lub optic xim muaj nyob rau hauv cov hlwb uas hnov tau ntawm Retina. Cov pigments pom yog ib hom tshuaj pom nyob hauv cov tsiaj lub nceeg vaj thaum lub ntuj xaiv tau hloov kho kom haum rau ib puag ncig lub teeb. Lawv cov tshuaj lom neeg yog ua tau ib tug xim xim muaj protein nrog cov chromophores ua cov pab pawg pab pawg.
Retinal HmoovYog ib daim tawv nqaij tu cov khoom xyaw uas nquag muaj cov khoom xyaw uas muaj los tiv thaiv wrinkle, tiv thaiv kev laus thiab tawm tsam kev tawm tsam. Cov kev tshawb fawb qhia tau tias piv nrog lwm cov vitamin ib feem ntau siv cov roj ntsha (piv txwv, tretinoin), retinal yog tsawg dua ntawm daim tawv nqaij thiab yog qhov haum rau rhiab tawv. Tsis tas li ntawd, rov ua dua, tom qab tau ua kom metabolized nyob rau hauv tib neeg lub cev thiab hloov mus rau hauv receinic acid, kuj muaj cov nyhuv ntawm kev kho pob txuv. Nws tuaj yeem hais tau kom muaj ntau yam kev ua haujlwm ntxiv.

Puas yog retinal zoo dua li retinol?
Retinal HmoovYog paub tias yuav siv tau ob qho tib si (tsawg dua kev hloov pauv hloov tshiab hauv peb lub cev, thiab cov tawv nqaij ua ntej tuaj yeem hloov pauv ntawm cov khoom thiab cov tawv nqaij), thiab muaj peev xwm txo qis dua.
Kuv puas tuaj yeem sib xyaw retinol thiab retinal?
"Retinol thiab retinal tuaj yeem siv ua ke tab sis nws yog nyob ntawm cov qauv tsim thiab tus kheej cov tawv nqaij.
Puas muaj kev sib deev nyab xeeb?
Retinal, zoo li lwm tus tswvcuab ntawm tsev neeg Retinnoid muaj qee cov kev mob tshwm sim. Cov kev tawm tsam muaj xws li suav nrog liab, dryness, flaking lossis me tingling ensation.
Mechanism ntawm Kev Ua
Retinal yog lub teeb liab tseem ceeb transduction molecule hauv qhov kev loj hlob ntawm qhov muag thiab nws si ntau txoj kev loj hlob thiab qhov tseem ceeb hauv kev txhim kho ntawm vertebrates. Myopia yog kev loj hlob. Cov dilation nquag ntawm sclera lub qhov muag myopic yog qhov tseem ceeb ua ke, thiab rov ua dua lub suab me me ntawm kev sim myopic qhov muag. Qee qhov kev nce qib tau ua rau hauv kev tshawb fawb ntawm kev sib raug zoo ntawm kev rov qab thiab qhov tshwm sim thiab kev txhim kho kev sim myopia. Txoj kev kawm no xyuas cov retinal thiab nws cov khoom plig nuclear. Cov kev tshawb fawb ntawm kev hloov pauv ntawm retina, choroid thiab sclera ntawm kev sim myopic ob lub qhov muag rau kis tau lub cim ntawm lub qhov muag elongation los ntawm retina rau sclera.
