12 molecular machines of Christmas | Ribosome

My molecular machine of Christmas is the ribosome. Ribosomes are very important because they are the protein factories of every single living cell, across every species. We can imagine a ribosome as a very, very, very, very tiny elf toy workshop but instead of building toys, it is assembling proteins. Why are proteins so important? …

Molecular Prosthetics: Small Molecules Replace Missing Proteins

Molecular Prosthetics: Small Molecules Replace Missing Proteins

Hi, my name is Marty Burke, I am a professor of chemistry at the University of Illinois and a member of the Carle Illinois College of Medicine. So molecular prosthetics is the idea that we can use small molecules to do the job of a missing protein thereby treating diseases caused by protein deficiency. So …

Understanding Crystallography – Part 1: From Proteins to Crystals

Understanding Crystallography – Part 1: From Proteins to Crystals

This is a three dimensional structure of a protein called lysozyme. It represents the order of nature. And I feel awed when I look at it. It’s an enzyme that’s in our tears and saliva and mucus, and it helps us fight bacteria. And knowing this three dimensional structure helps us to understand the mechanism …

Fundamentals of Nutrients and the History of Nutrition

[MUSIC] In order to survive, the human organism needs to take in oxygen, water, and food. We can survive only about three minutes without air, three days without water, and three weeks without food. Because food is so important to our survival, it’s been studied extensively. And since 1827 when a British physician by the …
