The toad retina diacylglycerol content is high and enriched in docosahexaenoate, both in comparison with toad brain and mammalian retina (Aveldano & Bazán, 1973, 1974) as well as with mammalian brain diacylglycerols (Sun, 1970; Keough et al., 1972; Aveldano & Bazán, 1975) where arachidonic acid predominates. This suggested that diacylglycerols in the toad retina may be uniquely engaged in the metabolism of 22:6-containing membrane lipids. Here we report an analysis of acyl groups and molecular species showing further peculiarities in toad retina lipids. In addition the cattle and toad retina glycerolipid labeling by 14C-glycerol and 3H-arachidonic acid is surveyed.
