Why was it unexpected that transporter proteins are required for transmembrane fatty acid transport?

#Unit 2. Cellular Organization

  1. because these molecules are too small for their diffusion to be impeded by membranes

  2. because it is the cytosolic fatty acid binding-protein–fatty acid complex that is the actual transported complex

  3. because these molecules are sufficiently hydrophobic to diffuse across membranes

  4. because triglycerides carried by lipoproteins were thought to be the only source of fatty acids in the circulation
