Which one of the following terms best describes a phospholipid. It consists of a: A. polar head and polar tail B. non-polar head and a polar tail C. polar head and non-polar tail D. non-polar head and a non-polar tail
Option C.polar = hydrophilic head of phosphate (which can dissolve in the aqueous extracellular answer because water molecules are polar); non-polar = hydrophobic tails of lipid, which being non-polar, can't dissolve in aqueous solutions.
