Pregunta 7

Pregunta
A phospholipid can be thought of having a [blank_start]polar[blank_end] 'head', consisting of a [blank_start]glycerol[blank_end] and [blank_start]phosphoric acid[blank_end] group, and [blank_start]hydrophobic[blank_end] 'tails', consisting of [blank_start]fatty acid chains[blank_end]. Phospholipids are the most predominant molecule in the [blank_start]bilayer[blank_end] forming plasma membranes.
