How to Determine Reactiveness/Lability of a Metal

The video discusses common chemical reactions involving metals such as oxidation and reduction, the formation of positive ions, and redox reactions. It also shows the results of experiments where different metals react with water and...

Part II of The Scientific Revolution explores the latter half of this movement and the gradual acceptance of scientific truth. This fascinating period of history chronicles European society's emergence from church domination that...

Lipid Biosynthesis Phospholipid Synthesis 2 Cholines, Serines, & Ethanolamines

Amino Acid Catabolism to Alpha-Ketoglutarate

The video discusses a required practical activity from the chemistry specification, which is an experiment to investigate how increasing the concentration of a reactant affects the rate of the reaction by observing a precipitate. The...

Carbohydrate Structure Aldopentoses and Ketopentoses

Adenylate Cyclase Mechanism Inorganic Pyrophosphatase Mechanism

Histidine Catabolism to Glutamate

In this video, we explore the deep gluteal muscles that facilitate hip external rotation including origins, insertions, actions, and innervation.

In this video, I explain the basis of spinal cord assessment using the ASIA scoring system and work through and example of how to assess spinal cord pathology using the ASIA score sheet [neurological levels of injury, zone of partial...

Allostery High EC vs Low EC

UCLA is full of amazing scientists! What do they all do? Well, pretty much everything you can imagine, but in this series we will meet as many of them as we can, one by one! Let's start with geophysicist Jon Aurnou. He studies fluid...

Carbonic Anhydrase

This video explains the classification of different organic reactions into different groups such as oxidation, reduction, substitution, elimination, and addition. The video goes on to explain four different types of reactions, including...

The video discusses the conservation of mass in chemical reactions and the application of this principle in calculating the mass of reactants and products. It also explores the features of chemical equations such as balancing and state...

Dianna Cowern runs Physics Girl full time. Here she discusses her path to studying physics and doing physics research before moving on to other, less prestigious, career pursuits.

In this video, we will discuss the following:

[1] the synthesis of thyroid hormones, T3 and T4, from iodide and thyroglobulin in follicular c
ells.
[2] the activation of T4 to T3 which occurs at the target c
ell level.
[3]...

In the previous tutorial, we learned about some five-membered aromatic heterocycles. Those were furan, thiophene, and pyrrole. Now let's learn about a six-membered one, pyridine. This one is ubiquitous in nature, so let's get the scoop...

In this video, we discuss the anatomy of the human scapula using images and a 3D model.

In this segment, we continue our discussion on Western diseases and explore how sugar, chronically elevated insulin, and inflammation lead to a diseased cardiovascular system.

This video provides an explanation of what diffusion is, how it occurs, and how to change the rate of diffusion. The concept of diffusion is demonstrated through the example of a plate of food emitting a smell that travels across a room....

Professor Dave explains the science and theory behind pericyclic reactions (Part Three)

Take in a deep breath of salty ocean air and more than likely you're also breathing in naturally occurring sea spray aerosols. But, there's much more in each of those tiny bursting ""bubbles"" than salt. They're also bursting with ocean...
