Extracted text: Indigenous populations of Southern Africa have traditionally eaten a spiny succulent plant called Hoodia gordonii to supress appetite when making long hunting trips across the Kalahari Desert. Weight-loss researchers in the US have marketed the active ingredient in this endangered plant , a steroid, as a spray gel which they claim is directly absorbed through the skin. Using what you know about how molecules move across phospholipid bilayers, do you think this drug can be absorbed this way? O Yes, small hydrophilic molecules can pass through the phospholipid bilayer. O No, hydrophobic molecules get caught in the hydrophobic center of the phospholipid bilayer. O Yes, small hydrophobic molecules pass through the phospholipid bilayer. O No, only natural molecules normally found in the body can pass through the phopholipid bilayer.
