Summary Introduction
To review:
The formation of protocells inside water from the cluster of proteins, lipids, and
Introduction:
The fatty acids form micelles inside water. These micelles consist of two important parts: a hydrophobic tail and a hydrophilic head. The hydrophobic head is water repelling and the hydrophilic tail is water loving.
