bathorhodopsin
/ˌbaθərə(ʊ)ˈdɒpsɪn/(also bathrhodopsin) Biochemistry
noun
An isomer of rhodopsin that is formed when light is absorbed by the chromophoric part of the molecule and (unless stabilized at very low temperature) changes spontaneously to lumirhodopsin.
Origin
1970s. From ancient Greek βάθος depth + rhodopsin, so called with reference to a spectral shift to lower frequencies.
