CM-5b: Hydrogen Bonds and the Alpha Helix

Hydrogen bonding is a key intermolecular force in stabilizing this structure. (Previously recorded)

CM-5a: Peptide Bonds and the Alpha Helix

Now we move into greater complexity and see how the peptide bond and alpha helix are built. (Previously recorded)

CM-4c: Protein Structure (Introduction)

Now we can move on to the "big" stuff. Let's prime ourselves to talk about protein structure. (Previously recorded)

Time - 5:35

CM-4b: Peptides

Ok, we've dealt a lot with amino acids. However, they can be joined to make peptides. Let's talk about them. (Previously recorded)

CM-4a: Calculaton of pI

Even though amino acids are never uncharged in aqueous solution, there can be a "net neutrality." (Previously recorded)

Time - 16:39

CM-4d: Protein 3D Structure

A protein without a defined structure, doesn't have a defined function. Let's talk about how structure is defined in proteins. (Previously recorded)

CM-3c: Calculation of Net Charge (amino acids and peptides)

Amino acids are never uncharged in solution. What's cool is that we can calculate to what degree it will be charged if we know the pKa values for the amino acid and the pH of the solution. (Previously recorded)

CM 3b: pH and pKa Relationships

Like any other weak acid, the pKa values of an amino acid's titratable groups provides valuable information. (Previously recorded)

Time - 9:14

CM-3a: Amino Acid - Titrations

Amino acids are also weak acids and they behave as such. Let's consider how a titration of a weak acid may look. (Previously recorded)

SP-2: Titration Curves

Have you ever really thought about what is happening during a titration and how it relates to the appearance of titration curves? Check this out and maybe you'll have a new appreciation for the concept. (Previously recorded)
