11cisretinalista

11cisretinalista is a term that appears in limited sources as a hypothetical or nonstandard name for a retinal compound with a cis configuration at the 11th carbon. It is not a recognized IUPAC name and does not appear in major chemical databases. In mainstream biochemistry, the relevant chromophore is 11-cis-retinal, a vitamin A aldehyde that binds to opsin to form the visual pigment rhodopsin in photoreceptor cells. On photon absorption, 11-cis-retinal is isomerized to all-trans-retinal, initiating a cascade that leads to vision.

As a term, 11cisretinalista could be used in speculative discussions, fictional contexts, or as a misnomer; if used, its exact structure and properties are not standardized and would vary by author. Without a clear structural definition, the term lacks experimental data and peer-reviewed support.

The existence of 11cisretinalista as a named entity does not imply any verified chemistry; it is best understood as a nonstandard or informal label rather than established scientific nomenclature. When aiming for precise communication, researchers typically refer to 11-cis-retinal or related retinal isomers with clearly defined structures.
