Lipidomics, en route to accurate quantitation

Abstract

Accurate quantitation is prerequisite for the sustainable development of lipidomics via enabling its applications in various biological and biomedical settings. In this review, the technical considerations and limitations of existent lipidomics technologies, particularly in terms of accurate quantitation; as well as the potential sources of errors along a typical lipidomic workflow that could ultimately give rise to quantitative inaccuracies will be addressed. Furthermore, the pressing need to exercise stricter definitions of terms and protocol standardization pertaining to quantitative lipidomics will be critically discussed, as quantitative accuracy may substantially impact upon the persevering development of lipidomics in the long run.
