Aquaporins exclude passage of hydronium ions (H30+). But recent research has revealed a role for some aquaporins in fat metabolism, in which they allow passage of glycerol, a three-carbon alcohol (see Figure 5.11), as well as H20. Since H30+ is much closer in size to water than is glycerol, what do y
