Application
视黄醇作为标准品，通过超高效液相色谱-串联质谱仪（UPLC-MS / MS），检测和定量维生素。
Biochem/physiol Actions
视黄醇及其衍生物有抗衰老特性。视黄醇用于治疗皱纹和衰老迹象。然而，由于其对光不稳定加上对皮肤具有刺激性，几乎不用于化妆品配方。视黄醇也用作皮肤病的治疗剂。缺乏会导致干燥症和毛囊角化过度症。
General description
视网膜的视黄醇和视黄酸是一种醛，是维生素A的醇和酸形式。类视黄醇存在许多空间异构体，因为它的脂肪链有不饱和键。视黄醇具有广泛的生物活性。
视黄醇或全反式视黄醇是20碳分子，含环己烯基环、带四个双键（均为 反式 构型）的侧链和末端醇基。

We discuss vitamin A with emphasis on its absorption, transport, cellular uptake, storage, and intracellular metabolism. Dietary retinyl esters are hydrolyzed to retinol in the intestinal lumen before absorption by enterocytes. Carotenoids are absorbed and then partially converted to retinol
