This protein is highly selective to water molecules , preventing the passage of ions and other solutes.There are multiple types of aquaporins that can allow the transport of other molecules such as glycerol,CO2, ammonia and urea by aquaglyceroporin. It depends on the size of the pore; aquaporin 3 channel has a pore width of 8-10 Ångströms and allows the passage of hydrophilic molecules ranging between 150-200 Da. Aquaporins water channel are impermeable to protons and other charged species | This protein is highly selective to water molecules , preventing the passage of ions and other solutes.There are multiple types of aquaporins that can allow the transport of other molecules such as glycerol,CO2, ammonia and urea by aquaglyceroporin.

Aquaporin is a six transmembrane alpha helices; the amino and craboxyl terminal are located at the cytoplasm. The protein is divided into two halves of similar sequence. Aquaporin is a tetramer, each monomer is able to channel water. | |||
