retinene

This enzyme is also called retinene oxidase.

Other names in common use include retinene isomerase, and retinoid isomerase.

If the diet is deficient in vitamin A, the body's stores eventually give out and retinene is not replaced as it is lost.

The molecule of rhodopsin is made up of two parts: a protein, opsin, and a nonprotein portion, very similar in structure to vitamin A, which is retinene.

In the visual system, retinal, technically called retinene or "retinaldehyde", is a light-sensitive retinene molecule found in the rods and cones of the retina.

The Retinenes (Retinene and Retinene) are chemical derivatives of the dietary supplement vitamin A (see retinol) formed through oxidation reactions.

"The names of all these molecules have recently been changed ... vitamin A is now retinol, retinene is retinal; there is also retinoic acid"-George Wald (1967).

Vitamin A, which is more stable, is, however, easily converted into retinene, so that the vitamin A stores of the body can be called upon to replace the constant dribbling loss of this visual pigment.

Other names in common use include retinol (vitamin A1) dehydrogenase, MDR, microsomal retinol dehydrogenase, all-trans retinol dehydrogenase, retinal reductase, and retinene reductase.
