从红藻Gracilariopsis lemaneiformis中分离得到一种前所未有的含醛双半乳糖二酰基甘油(DGDAG)，并对其结构进行了确定。其结构经核磁共振、质谱学和降解成简单碎片的方法确定为1-O-[5-羟基-12-氧代十二烷-6(E)，8(E)，10(E)-trienoyl]-2-O-palmitoyl-3-O-[-β-D-galactopyranosyl-6，1-α-D-galactopyranosyl]-glycerol]。该含醛DGDAG与G。Lemaneiformis，除了我们之前发现的不寻常的半乳脂外，进一步表明这种藻类具有独特的脂氧合酶能力。
An unprecedented aldehyde-containing digalactosyldi-acylglycerol (DGDAG) has been isolated from the red algaGracilariopsis lemaneiformisand structurally defined. Its structure was determined as 1-O-[5-hydroxy-12-oxododeca-6(E), 8(E), 10(E)-trienoyl]-2-O-palmitoyl-3-O-[-β-D-galactopyranosyl-6,1-α-D-galactopyranosyl]-glycerol by nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry and degradation to simple fragments. The identification of this aldehyde-containing DGDAG fromG. lemaneiformis, in addition to our previous findings of unusual galactolipids, further indicates that this alga has unique lipoxygenase capacities.
