Chapter 2.2: Biological Molecules: Lipids

This video explains the formation of ester bonds between fatty acids and alcohol to make lipids. The video shows how triglycerides are formed by the addition of three fatty acid chains to glycerol and also explains the arrangement and functions of phospholipids in the cell membrane. There are a few seconds where the video shows an interesting fact about cholesterol. Did you know that cholesterol production is increased due to our consumption of inflammatory foods? :)

Watch this video for the second section of the second chapter of the AS Biology syllabus. It is perfect for revision or to just reinforce your understanding of Biological Molecules. Take it as a Lipids crash course :)
