Dr. Orion Berryman talks with Hank about the cool chemistry going on in his lab, and Jessi from Animal Wonders brings in Prickle the Hedgehog!

Cone snails are venomous marine snails who use their venom in creative ways to take down their prey. And scientists have realized that certain chemicals in these venoms could actually be pretty useful for medicine.

Along with a crew of technologists and scientists, Jorge Soto is developing a simple, noninvasive, open-source test that looks for early signs of multiple forms of cancer. Onstage at TEDGlobal 2014, he demonstrates a working prototype of...

Alkenes are an important type of molecule in organic chemistry that we’re going to see a lot more of in this series. But before we can really get into the many cool reactions alkenes do, we need to go over some of the basics. In this...

What are biologic drugs? What about biosimilars? In a previous video we compared brand name and generic drugs. But we kind of left out a major player in the world of medicines; biologic drugs. These complicated little guys probably...

Passive transport includes diffusion, facilitated diffusion, and osmosis, all of which move substances down their concentration gradients without energy input. Small, uncharged molecules like oxygen and carbon dioxide diffuse freely,...

The plasma membrane or cell membrane is an intricate structure made of macromolecules that work together to protect the cell. Think of it as the security guard of the cell - letting important substances in, and letting others out.

Covalent bonds are very strong can be used to make a range of substances from the very small 'Simple Molecular Substances' to the large 'Giant Covalent Structures'. Learn how their properties differ and why!

Watch the first part of our Carbon Cycle videos, as part of environmental chemistry. Photosynthesis and respiration help carbon to be cycled in nature by using energy from the sun. As living things grow, they have to build up large...

This video provides a comprehensive overview of the human digestive system, including the two types of digestion (mechanical and chemical), the three basic food types (carbohydrates, proteins, and fats), and the enzymes involved in...

The Smooth Endoplasmic Reticulum for Anatomy and Physiology

We know that neurotransmitters are signaling molecules that travel across the synaptic space to interact with receptors and propagate signals from one neuron to the next. But what are these molecules? What are their structures? How do...

In this lecture, I first deal with the functions of the digestive system. We then take a journey through the digestive system by following your food from your mouth all the way through your body and even through the elimination of...

In the early 19th century, we were still in the habit of searching for plants with medicinal properties. But we were finally beginning to develop the capacity to identify active ingredients within those plants, isolate them, and purify...

Drugs of all varieties are very interesting from a biochemical standpoint, as they produce an incredible array of physiological effects. These effects are due to the shape of each molecule, which determines the cellular components they...

We just learned about drug administration, or the ways that drugs can enter the body. What happens next? How do drugs move around the body to get to where they need to go? The study of this is called pharmacokinetics. Let's get into the...

It's amazing to think that we've gone from having no idea what air is, to knowing its composition intimately, and even having the ability to filter what's in it. We have produced machines that can remove both pathogens as well as harmful...

This video explores the innovative engineering solutions being used by the Orange County Water District to replenish the groundwater basin and provide safe drinking water to the cities in Orange County. The video also highlights the...

In this video learn how fractional distillation separates crude oil into useful fractions, examples of these fractions and where they're used in everyday life.

How does your body break down the food you eat to generate the energy you need to get through your day? What form of energy is this, anyway? Let's go over some of the basics of metabolic processes, and introduce ATP, the currency of...

Learn the basics about covalent bonds, when learning about properties of matter. When similar atoms react, like non-metals combining with other non-metals, they share electrons. This is covalent bonding. Non-metals have shells of...

Small intestine and food absorption Digestion goes hand in hand with absorption… which happens in your small intestine. Which is what we’re going to look at in this video. So keep watching!
