And he was, of course, theįirst person to discover the chemical composition of pure urea, the main component of urine.

By day, he was a practicing physician but every morning beforeīreakfast he did research in his home laboratory in London. The body's chemistry was to understand what it does to food.

Thought that the best way to understand the humanīody was through chemistry. He became fascinated with human digestion,Įspecially our urine. In the den so that must mean that it's time for the mostĪwkwardly named segment here on crash course, Biolography. (upbeat music) Wow, my goodness, I'm back We have to thank a little known English physician, who hundreds of yearsĪgo dedicated his life to the study of human pee. It's no coincidence that weĬlassify them in the same way that we classify food. Lipids, the Proteins, and the Nucleic Acids. To ultimately pass those same instructions on the That all organisms use to be born, to grow and They are essential sources of energy, they are the means of storing that energy, they are also the instructions Necessary for every living thing on Earth to survive. Or if you're Lady Gaga or if you're a mite living on the Queen of England's eyelashes.

I don't care if you're a bacterium or if you're a blue whale Talk about the molecules that make up every living thing and every living thing (upbeat music) So far we've talked about carbon and we've talked about water. Who taught us everything that we know about urine.

I'm going to talk to you about three different things. I'm making lunch today, I wanted to sort of use it as a lab. Today because last week we started off in my bathroom, and I kinda feel bad about that, and also because as
