Abstract

The phospholipid class and fatty acid composition of photoreceptor membranes, mitochondria, microsomes and nuclei of bovine retina are reported. All contain phosphatidyl choline and phosphatidyl ethanolamine as their major components. Docosahexaenoic acid is the major polyunsaturate in all lipid classes except phosphatidyl inositol, where arachidonic acid predominates. Photoreceptor membranes differ from the other organelles in two major respects: (1) they do not contain ethanolamine plasmalogens; and (2) phosphatidyl serine contains 24 carbon polyunsaturates. Other minor differences are noted.

    Citation Excerpt :

    Phosphatidylinositol is a comparatively large component of the membranes of most cells in metazoans ranging from 4 to 20 mol% of total phospholipid (1, 14), and analysis of phosphatidylinositol in six different mammalian species shows 4.4–6.4% mol% of total retina phospholipid (14–17). Studies have shown that retinal ROS membranes contain lower levels of PI than do retinal pigment epithelium (RPE) cells (18) and ER membranes isolated from bovine retinas (19). Recently, Wensel’s laboratory reported that ROSs and fragments of inner segments contain PI(3)P at 0.0035 mol% and PI(4)P and PI(4,5)P2 on the order of 0.04 mol%, 10-fold higher than the levels of PI(3)P of total phospholipid (14).
