小说从无教养的心磷脂Methane-Metabolizing古生菌
表1
描述小说PG-based ARs次封盖和代表分裂模式观察(缩写看到文本)。连续亏损的烷基链碎片一起显示剩余headgroup当附着在甘油骨架包含C
20:0链。括号中的值表明损失最直接的前兆,而不是父离子;(*)表示不饱和现象的存在或在isoprenoidal - oh基团链,不是由女士
2光谱;* *从headgroup OH-phytanyl链和己糖的损失;(* * *)丝氨酸损失+水从headgroup两链仍然连接(见图
2)。碎片由于烷基链编码的损失:
强调了(不饱和链片段产生的损失),大胆的(C片段产生的损失
25链),
斜体(碎片造成损失的羟化phytanyl链)。H的额外损失
2发生在阿羟化烷基半个,但是并不指定。所有父离子识别显示
ppm;所有的片段标识
ppm。
