Believe it or not, steak, coffee beans, caramel, and toast have something in common. It's called The Maillard Reaction and it is the reason that things get browned when they are heated. It is a chemical reaction of sugars with amino acids. Dr. Kiki helps explain this process. Run time 03:38

DNA contains the genetic information of an organism. It is essential to all living things. The structure and role of the nucleic acids, DNA and RNA, are investigated. DNA codes for the arrangement of amino acids in proteins. When the DNA has a mutation, it often results in a malfunctioning of proteins which leads to genetic diseases.

Proteins are very important to living organisms and to industry. Proteins are part of the chemistry of life, and the program examines proteins — polymers built from only 20 basic amino acids. The arrangements of these long chains of amino acid are important to their functioning. The video also explores the history of the discovery of the structure and function of proteins.

Sometimes great food and heartburn go hand in hand. Many people rely on products like Milk of Magnesia to settle their stomachs, but have you ever wondered how those antacids really work? This highly visual demonstration from Steve Spangler will show you exactly how Milk of Magnesia neutralizes the acids in your stomach - using some cool color changing chemistry - and saves the day after a great meal.

One common belief is that a compound in turkey known as tryptophan makes people especially drowsy, but we're here to debunk this holiday myth. Some of the key vocabulary words include melatonin, seratonin, tryptophan, amino acids, and protein. There are several good diagrams that help to explain what makes you drowsy after Thanksgiving dinner. (02:24)

This is an excellent video that teaches about acids and bases. The "trick" is a simple experiment that is fun for students to learn about indicators of ph. The MIT student shows the trick and explains that household chemicals can be acids or bases and can be easily tested with an indicator made from purple cabbage. (11:25)
