Following the production of membrane extracts using the non-ionic detergent Triton X-100, you fractionated the membrane lysates in small batches and analyzed individual batches by mass spectrometry. In a particular membrane fraction, you noticed a high content of cholesterol, sphingolipids with long fatty acid chains and large amounts of GPI-anchored proteins. The membrane fraction probably has which of the following? O porins O lipid rafts O micelles O lipid droplets

These data suggest which of the following? The cells used in the study do not have membrane microdomains. Fillipin induces the formation of membrane microdomains. X-CFP and Y-YFP are near neighbors only when membrane microdomains are present. Cholesterol is required for X-CFP and Y-YFP to fluoresce. Cholesterol allows membrane proteins to diffuse away from membrane microdomains. State the rationale for your answer. The lateral structures of the plasma membrane component are membrane microdomains that are enriched with glycosphingolipids and cholesterol, containing glycosylphosphatidylinositol (GPI) anchored proteins (Harder, 1998).

Question 1 (1 point) What complexes are composed of cholesterol and lipids that contain the sphingosine backbone, including sphingomyelin and certain glycolipids, and with GPI-anchored proteins? flip-flop lipid rafts planar bilayer membrane myelin aggregates

Following the production of membrane extracts using the nonionic detergent Triton $X-100$, you analyze the membrane lysates via mass spectrometry and note a high content of cholesterol and sphingolipids. Furthermore, biochemical analysis of the lysates reveals potential kinase activity. What have you likely isolated?
