Spectral characterization of the neuronal pigments of Aplysia juliana

, : Spectral characterization of the neuronal pigments of Aplysia juliana. Biochimica et Biophysica Acta 584(2): 339-345

Spectral analysis at liquid N2 temperature of the circumesophageal ganglia of Aplysia juliana showed that carotenoids and a hemoglobin-like pigment are contained in concentrations of approx. 25 and 3 micronM, respectively, in the whole ganglia. Microspectrophotometrical measurements of Aplysia neurons indicated that the carotenoids reside on lipochondria in a concentration of approx. 38 mM. In addition to lipochondria, two types of pigmented particulate having absorption maxima at about 512 and 525 nm, respectively, were found in the neurons. The neuronal carotenoids consist of violaxanthin, beta-carotene and one minor component; among them the first occupies approx. 77% of total carotenoids. Two principal absorption maxima of the carotenoids, when existing in both ganglial homogenates and Triton X-100 extracts, show a red shift of 10 nm compared with those of free pigments in hexan. The red shift may be interpreted as due to the solvation of the carotenoids by surrounding lipids.
