In this video Paul Andersen describes the lipids (of the fats). He explains how they are an important source of energy but are also required to cell membranes. He explains how the hydrocarbon tails in triglycerides contain energy available for life. He also explains how phospholipids construct, and cholesterol molecules main the cell membrane.

I found this video to be very helpful when studying for lipids. It was concise, short, straight to the point, short, well-explained and did i mention short! LOL However, even thought the vid was only 7mins and 05sec. there were a lot of things that he went through. I especially liked his method of teaching as the video was generally fun to watch as well as listen to.
Some of the Key points discussed in the video are:
- lipids /fats that is found in butter or olive oil is what we call a triglyceride.
- it contains a glyceral head and 3 fatty acid tails
- the tail is where the energy lies
- when we eat fat it is broken down by enzymes called lipases
- this is where we get the energy from
- energy is stored via fats in the body and then we burn these fats when needed.
- fats in addition to providing energy also provides thesurroundings such as cholesterol with a bilayer phospholipid head.
- energy comes from the hydrocarbons.
- saturated fats are solid at room temp, because of the single bonds.
- unstaurated fats because of the double bonds, puts a bend in the tail causing it to be kinky. therefore it cannot be packed together so it is a liquid at room temp.
