Lipids Part 1: TAGs, Fatty Acids, and Terpenes

What's butter made of? What about olive oil? Well they're lipids, which are largely nonpolar substances. Why is one solid at room temperature and the other is liquid? What are trans fats and why are they bad for you? Let's find out all this and more!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

Hi Professor Dave,
Thank you for explaining to me today. I just wanted to say that you are the Bill Nye to the Pre-med/Medical community. We love you.

[travisbickle]

Good to know he spares some time between Foo Fighters rehearsals to teach some biochem:D

[christinac]

Keep singing that intro randomly throughout the day...

Who have an exam and he doesn't know anything so came here to understand the materials?!
Thanks professor Dave you always save me 🤍

[nimcegervacio]

I sincerely thank you, Prof. Dave for all these educational videos. They helped me a lot.

[DaniFilth]

Love your videos, they got me through my OC-exam. Using your new biochemistry-videos I can now prepare for the practical during the winter-term.

[kycelberjamin]

Gosh my professor raps the lesson. Thank God found this.

Terpenes are also used as an alternative to organic solvents that have relatively higher toxicity, like Xylenes. Citrisolv is probably the most common one used as an alternative solvent. It is a Terpene hydrocarbon, D-Limonene, and smells a bit like an orange flavored aerosol. But after smelling it for more than 10 minutes or so, it begins to become a rather "rich" concentrated type of odor and can make some people feel nauseated or start having a mild headache. Nevertheless, it's a much better alternative in terms of protecting the long-term health of your laboratory workers. Some procedures in clinical labs can't always get the same level of effectiveness with immunohistochemistry slide work by using D-Limonene based solvent, so o-Xylene is sometimes the only solvent that is able to work effectively for them. But it's at least worth a try to test out a D-Limonene just to see if it's feasible for using.

I need a teacher as good as Dave because my teacher taught us in such a complex way even tho i aint in a ap/honors group

[animelover]

My science teacher shows us your videos.😊😀😁

[suprathikvineesh]

man's being useful from pre-med tests to first year finals

Vanderwaal's are really weak bonds too, so that makes sense about how soaps work and interact with water.

[gilong]

Cool I'll think of micelles every time I was my hand!

[hiranthini]

Prof Dave, I really appreciate your videos, and clear explanations, it really helps my understanding ... THANKS

[Sukunapookie]

Man I love you so much ..you are saving my ass for the exam..thank you ❤❤

[호린커플]

Thank you so much for the great video! I was struggling with my university studies but starting to understand now with your videos :) One question, what does it mean by "double bonds are almost always cis"?

[bonifaceetimeojuka]

Like today's presentation about lipids

[morganbattaglia]

I love your channel, and I watch it all the time for bio, and for fun.
