(Table 2) Abundance of the detected intact polar lipids (IPL) in surface and subsurface sediments during R/V Pelagia cruise PASOM in January 2009@en

- abundance per gram dry weight; 0 = not detected - DH isomers were detected as a GDGT with a glycosidically-bound hexose moieity on both ends of the core (I) and with one glycosidically-bound dihexose moiety on one end (II). - HCP is an IPL-type with an ether-bound cyclopentanetetraol moiety on one end and an hexose moiety on the other (previously reported as GDNT; e.g. De Rosa and Gambacorta, 1988; Sturt et al., 2004).- 每克干重的丰度；0表示未检出 - DH异构体被鉴定为一类甘油二烷基甘油四醚（GDGT）：其核心两端均带有糖苷键结合的己糖基团（结构I），且其中一端带有糖苷键结合的二己糖基团（结构II）。 - HCP属于完整极性脂（Intact Polar Lipids，IPL）类型：其一端带有醚键结合的环戊烷四醇基团，另一端带有己糖基团（此前曾被记作GDNT；例如De Rosa与Gambacorta，1988；Sturt等，2004）。
