12. Endocrinology

(April 26, 2010) William Peterson and Tom McFadden introduce the field of endocrinology. They explore at the contextual basis of the endocrine system, peptide vs. steroid hormones, the processes by which the brain controls hormones, and hormonal influence on the brain.

Excellent video and explanations. Thank you.

The start for cholesterol synthesis is the formation of AcetoAcetyl-CoA that will be condensed with another Acetyl-CoA to form HMG-CoA, and there will be a series of condensation reactions between 2 isoprenic chemicals untill the formation of squalene, when it gets oxidated and then there's a cascade of reactions that will finally form cholesterol.

@ToonLiger He drew an indole group, and afaik (I am a biologist who works as a teacher) only tryptophan has that. Knowledge about the structure of the approx. 20 amino acids that go into making proteins has been around for at least 20 years (which is when I learned about it)!

Since my knowledge disagreed with the stuff presented, I was hoping someone would explain it to me. Without appealing to authority ("it is so coz someone from Stanford said so!").. :)

@mbhorsten are you seriously believing more wikipedia than a stanford class? so sad.

The fact that they used Harry Potter as examples made is lecture even better.

The brown hair guy Tom is hot. Im having a hard time concentrating because all I can think about is making out with him. My hormones are being released from my ovaries!

About 10 minutes in, Peterson mentions that all peptide hormones deriving from tyrosine. But when I looked it up on the wikipedia, the only amino acid with an indole group is tryptophan. What am I not getting?

Awesome series, even in spite of (possible) slipups like this. Thank you so much, Stanford!

I hate the way this guy talks. He is like the Dane Cook of endocrinology.

@slonamu No, it's definitely "guy". Listen to it again.

Nope.
