Due to the hydrophobic nature of membrane lipids, triglycerides and cholesterols, they require special transport proteins known as lipoproteins. The amphipathic structure of lipoproteins allows the triglycerides and cholesterol to be transported through the blood.
The passage explains that membrane lipids are hydrophobic (water-fearing) and require specialized transport proteins called lipoproteins for movement through the blood.  The unique structure of these lipoproteins allows them to carry triglycerides and cholesterol effectively.
