People like to say all kinds of things about protein – like, you need to eat lots of it to build muscle and lose weight. The truth is, the science of protein and how your body uses it is much more complicated than that. Hosted by: Hank...

If you celebrate American Thanksgiving, odds are you're full of food and pretty sleepy right about now. While you drift off for a post-feast nap, enjoy this compilation of episodes covering all kinds of different sleepy, science-y topics!

Flinching in response to an unexpected loud noise might not be pleasant, but it's also not a problem for most people. For one family, however, getting startled would cause their bodies to go stiff and fall.

People like to say all kinds of things about protein – like, you need to eat lots of it to build muscle and lose weight. The truth is, the science of protein and how your body uses it is much more complicated than that.

Around 20 years ago NASA launched a spacecraft to study the comet Wild-2. What it brought back would cause scientists to wonder whether the building blocks of life could have arrived at Earth on a comet.

SDS–PAGE is a widely used technique for qualitative analysis of protein mixtures, particularly during protein purification. Proteins are denatured using SDS and β-mercaptoethanol, which linearize the molecules and impart a uniform...

What is an amino acid? Learn about the structure, classification, types and functions of amino acids in this fun video.

In this video, Justin from the Institute of Human Anatomy discusses the anatomy and mechanisms behind the parasomnia disorder known as sleep paralysis. He explores how the brain enters this state and delves into the cultural associations...

Hey guys! In this video, I discuss the grouping and classification of amino acids. In particular, I discuss polar/non-polar, acidic/basic, branched chain amino acids, hydroxyl group containing amino acids, aromatic amino acids, and...

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...

Serine, Glycine Biosynthesis

Lesson on the purine synthesis and metabolism pathway, and the purpose, regulation and importance of the pathway in human physiology and health.



In this lesson, I discuss the two purines (adenine and guanine), the importance...

In this video I talk about the two types of receptors - the ionotropic and metabotropic receptors and show how the result in different types of responses. Enjoy!

In this video, we explore the theory of the hippurate hydrolysis [hippuricase] test and how to interpret the results.

Proteins are made of a long chain of amino acids, which has been coded for by DNA. The order of the bases of DNA determines which protein is made, by coding for a specific order of amino acids. This is protein synthesis, and in this...
