https://diler.tube/videos/watch/087eaa50-f266-4a21-aa73-939d2e35956f Molecules make you think of chemistry, right? Well, they also are very important in biology too. In this video we are going to look at carbohydrates, proteins and lipids. When I say lipids, I am talking about fats and oils. Life processes depend on biological molecules, whose structure is related to their function. Did you know that living organisms are actually made from quite a small group of molecules? What do you think the most common molecule in you is? It is actually water. About 55 to 60% of a human adult’s body weight comes from water. And in some organisms it can be up to 90% of their body weight!! [could show jellyfish here] Your muscles and kidneys are particularly ‘watery’ at 79%, but even your bones have 31% water. Bet you didn’t expect that! Does that mean we really can walk on water?!
