One-step separation system of bio-functional lipid compounds from natural sources
Autor: Alexandros Tsoupras, Katherine M. Pappas, Theodore G. Sotiroudis, Constantinos A. Demopoulos
Publikováno v: MethodsX, Vol 8, Iss , Pp 101380- (2021)
Lipids are a very heterogeneous class of biomolecules with distinct structures and functions. Total lipids (TLs) obtained from natural sources are regularly further separated into lipid subclasses, with the two major ones being the polar lipids (PLs)
