(under subclass 350) Proteins which are conjugated with a lipid.
(1) Note. Lipids include complex lipids which contain fatty acids as components (e.g., acylglycerols, phosphoglycerides, sphingolipids, etc.) and the simple lipids (terpenes and steroids).
(2) Note. This subclass provides for lipoprotein systems, i.e., transport lipoproteins and membrane systems, in which the lipid and protein are held together by hydrophobic interactions between the nonpolar portions of the lipid and protein components.
