“…Surprisingly, DAGE have been found in particularly high amounts in the zooplankton sea slug Clione limacina (Kattner et al, 1998;Phleger et al, 1997) and in the liver oil of the gonatid squid Berryteuthis magister (Hayashi et al, 1985), 28-40 and 27.5% of their total lipids, respectively. The crustacean Antarctic krill Euphausia superba (Fricke et al, 1986) has been reported to contain 0.3-0.6% DAGE. Recently, the Boreal Soft Coral Gersemia rubiformis (Imbs et al, 2006) has been reported to contain up to 12% DAGE of the total lipids.…”

The naturally occurring 1-O-alkyl-sn-glycerols and their methoxylated congeners, 1-O-(2'-methoxyalkyl)-sn-glycerols, are biologically active compounds, ubiquitously found in nature as diacyl glyceryl ether lipids and phosphoether lipids. The chief objective of this article is to provide a comprehensive and up to date review on such ether lipids. The occurrence and distribution of these compounds in nature are extensively reviewed, their chemical structure and molecular variety, their biosynthesis and chemical synthesis and, finally, their various biological effects are described and discussed. An unprecedented biosynthesis of the 2'-methoxylated alkylglycerols is proposed. The first synthesis of enantiopure (Z)-(2'R)-1-O-(2'-methoxyhexadec-4'-enyl)-sn-glycerol, the most prevalent 2'-methoxylated type alkylglycerol present in cartilaginous fish, is described. It was accomplished by a highly convergent five step process.
