How do we categorize drugs? How do we name them? This is quite a bit trickier than one might think, because there are different ways we might want to categorize them, each of which has its own application. Any drug also has multiple...

Revealing the Hidden Colors of the Microcosmos

Understanding Viruses - Viruses/Immunity Set - Part 1. This clip offers a simplified look at how viruses are structured and how they infect living host cells.

This video provides an overview of the element phosphorus and its significance in various aspects of life. Phosphorus is a vital element found in the human body and plays a crucial role in DNA, RNA, and energy transfer in cells....

The U.S. Department of Agriculture’s Center for Nutrition Policy and Promotion introduces the “MyPlate, MyWins” video series that shows how small changes to what you eat and drink add up. Whether at home or on-the-go, MyPlate can help...

This video provides basic dietary recommendations for athletes participating in intense sports activities. It emphasizes the importance of nutrition in maintaining muscular builds and explosive energy. The video highlights the need to...

Glucose Transporter (GLUT) How Does it Work

What are enzymes? Why they're nature's little factory workers. They chop up certain things! They build up others! Pretty amazing the kind of chemistry nature can do given enormous polypeptide chains with unfathomable variability and...

In this video we examine the process of digesting our food. We shall see how biological catalysts called enzymes break these food molecules apart and why they are necessary. Think of our food molecules as a train of trucks all coupled...

Cancer is the ultimate expiration date for biological life. But what is it? How does it occur? Is there anything we can do about it? Let's take a brief look at this incredibly complex issue.

What you eat after working out can make a difference in how your body recovers. Consuming the right types of snacks after exercising can help to replenish your energy, build muscle mass, and burn fat. Listen to this interview with a...

In this video, viewers are educated about the importance of nutrients for their body's proper functioning, growth, and repair. The video begins by highlighting the six major types of nutrients: carbohydrates, proteins, fats, vitamins,...

Everyone has heard of proteins. What are they on the molecular level? They're polymers of amino acids, of course. They make up most of your body, so we have to understand their structure very well! Check this out to learn the hierarchy...

Now that we know how drugs move through the body to reach their target, what happens once they get there? By what mechanisms can drugs interact with target proteins to elicit a particular cellular response, and by extension a...

We live in a time where there is much skepticism towards modern medicine. This stems purely from ignorance, however, and there are those who capitalize on this to sell an unbelievable array of alternative medicines that, almost without...

Cell Structure and Function Set: 2. This clip introduces the structure and function of the components of the nucleus.

In this episode, we discover a protein that could someday eliminate malaria, learn about microbes battling it out in Antarctica, explore super Wi-Fi that uses UHF channels and virtually unwrap a 1500-year-old scroll.

In this week's episode, we discover a protein that could someday eliminate malaria, learn about microbes battling it out in Antarctica, explore super Wi-Fi that uses UHF channels and virtually unwrap a 1500-year-old scroll.

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...

Protein is essential for life - we need protein to build muscle tissue, to make enzymes for our metabolic activity, to form the protective layer of our skin, to make DNA… in fact for most processes in our body. There are thought to be...

If this is the first time you have heard about antibodies, you may not know how important they are. Antibodies are one of the warriors inside our body, helping us to fight off nasty, invading particles. They are a type of protein, and...

Researchers at Michigan State University (MSU) have demonstrated how a new virus evolves, shedding light on how easy it can be for diseases to gain dangerous mutations. The findings appear in the current issue of the journal Science. The...

Proteins are the workhorses of cells. With support from the National Science Foundation, University of Arkansas biochemist James Hinton has been researching their structure and function for decades. Back in the 1990's, he had a vision to...
