Explore the parts of the cell membrane with The Amoeba Sisters! Video discusses phospholipid bilayer, cholesterol, peripheral proteins, integral proteins, glycoproteins, and glycolipids - as well as why the surface area to volume ratio...

Molecules come in infinite varieties, so in order to help the complicated chemical world make a little more sense, we classify and categorize them. One of the most important of those classifications is whether a molecule is...

Water can dissolve more substances than anything else on earth...so why doesn't it dissolve everything away?

Paul Andersen gives you a brief introduction to the cell membrane. He starts by describing amphipathic nature of a phospholipid and how it assembles into a membrane. He gives an overview of the fluid mosaic model inside cells. He...

In this video Paul Andersen explains how covalent bonds form between atoms that are sharing electrons. Atoms that have the same electronegativity create nonpolar covalent bonds. The bond energy and bond length can be determined by...

Mr. Andersen shows you how to determine if a bond is nonpolar covalent, polar covalent, or ionc.

Being able to determine if a molecule is polar or nonpolar is very important in chemistry as it allows you to then discuss intermolecular forces present in molecules which helps to predict various physical and chemical properties. In...

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...

These short, simple life hacks are based on physics. Detangle your headphones, remove sticker residue, check if sunglasses are polarized, cool your car faster, and avoid getting static shock!

Why do different liquids boil at different temperatures? It has to do with how strongly the molecules interact with each other. Find out all the different ways, and how to use them to make predictions about matter!

Phospholipase C, IP3, DAG, and Ca2+

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

In this section, I talk about the properties of water, and what makes it unique. I talk about hydrogen bonds that result from the polar nature of water and why ice floats.



I also deal with diffusion and go into the 3 factors...

The plasma membrane is responsible for maintaining a balance. In this section, I talk about both the structure and the function of the plasma membrane. I deal with the components of the plasma membrane and their functions.

A discussion of resistance, and how to understand it.

Ionic Bond, Covalent Bond, James Bond, so many bonds! What dictates which kind of bond will form? Electronegativity values, of course. Let's go through each type and what they're all about.
