4 It makes the nearby portion of a cell membrane less permeable to small molecules that are soluble in water. Cholesterol also functions in intracellular transport, cell signaling and nerve conduction. Cholesterol has several functions. 1 It helps to stiffen the membrane, making it less soft. 2 It also helps the membrane to remain relatively fluid (as in fluid mosaic model). 3 It also provides (lipid rafts) a suitable molecular environment for certain membrane proteins.
