The retinenes (retinene 1 and retinene 2) are chemical derivatives of vitamin A (see retinol) formed through oxidation reactions. Retinene 1 is better known as retinal and is fundamental in the transduction of light into visual signals in the photoreceptor level of …

视黄醛也称维生素A醛，是 视黄醇 氧化后的衍生物，分子式为C20H28O。 橙色结晶（从 石油醚 中析出）。 已知有六种 立体异构体，其中全反式最稳定，其 结构式 如概述图所示。 熔点61~64℃。 不溶于水，溶于 乙醇 、 氯仿 、 环己烷 、石油醚及油。 最初从 视网膜 中分离取得，后由 β-胡萝卜素 发生氧化断裂生成的。 其 生理效应 与视觉有关，一般认为它在光照作用下能引起快速的顺式-反式 异构化反应 [1]。 视黄醛是 视紫红质 的 辅基。 视觉细胞内11-顺式视黄醛 …

Retinal (also known as retinaldehyde) is a polyene chromophore. Retinal, bound to proteins called opsins, is the chemical basis of visual phototransduction, the light-detection stage of visual perception (vision). Some microorganisms use retinal to convert light into metabolic energy.

Retinene is a derivative of vitamin A that plays a crucial role in skincare products. It is known for its ability to promote cellular turnover, inhibit melanin production, and treat pigmentation and photoaging disorders.

Retinene, also known by its Latin origin ret′inin, is a crucial carotenoid pigment found in the photoreceptor cells of the retina, specifically within the rods. The term refers to two forms of the pigment—each playing a central role in vision and functioning as a precursor to Vitamin A.

In the surviving vertebrate retina the retinene 1 liberated by bleaching rhodopsin is converted quantitatively to vitamin A 1. Recent chemical studies have indicated that in this process the aldehyde group of retinene 1 is reduced to the primary …

The Retinenes (Retinene 1 and Retinene 2) are chemical derivatives of the dietary supplement vitamin A (see retinol) formed through oxidation reactions. Retinene 1 is better known as retinaldehyde or simply retinal and is fundamental in the transduction of light into visual signals in the photoreceptor level of the retina (known as the visual ...

2024年9月7日 · Retinene, also known as retinal or retinin, refers to two carotenoid pigments found in the rods of the retina, playing a vital role in vision. These pigments are derivatives of vitamin A and are activated by light, forming the basis of the photochemical reaction that allows us to see.

In the surviving vertebrate retina the retinene(1) liberated by bleaching rhodopsin is converted quantitatively to vitamin A(1). Recent chemical studies have indicated that in this process the aldehyde group of retinene(1) is reduced to the primary alcohol group …

retinene，英语单词，主要用作名词，作名词时译为“视网醛，视黄素；维生素A醛”。
