一般描述
磷脂酰丝氨酸（PtdSer）是阴离子磷脂，大量存在于真核细胞内。10%的总细胞脂质由磷脂酰丝氨酸组成。O-磷酸-L-丝氨酸是对热稳定的底物。
应用
17：0 Ps用作内标，用于BXD肝脏和血浆样品分析。 也可作为标准品，通过液相色谱-串联质谱，评估酿酒酵母细胞脂质组。
生化/生理作用
磷脂酰丝氨酸（PtdSer）参与细胞内各种信号通路。同时在细胞凋亡和血液凝结中起主要作用。

Lipids are structurally diverse amphipathic molecules that are insoluble in water. Lipids are essential contributors to the organization and function of biological membranes, energy storage and production, cellular signaling, vesicular transport of proteins, organelle biogenesis, and regulated cell death.

O-Acetylserine sulfhydrylase (OASS), a pyridoxal 5'-phosphate (PLP)-dependent enzyme, catalyzes the synthesis of L-cysteine from O-acetyl-L-serine and sulfide. O-Acetyl-L-serine is labile at high temperatures at which hyperthermophilic archaea live. Herein, a study of the substrate specificity of OASS from Aeropyrum pernix

Lipidomics requires the accurate annotation of lipids in complex samples to enable determination of their biological relevance. We demonstrate that unintentional in-source fragmentation (ISF, common in lipidomics) generates ions that have identical masses to other lipids. Lysophosphatidylcholines (LPC), for example
