He knows alot about science stuff.....Professor Dave Is BEST...

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.

Keep singing that intro randomly throughout the day...

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

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

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

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.

Excellent video. Thank you!

Thank you professor

Thank you professor❤❤

THANK U PROF DAVE🥺❤️

thank you so much professor Dave...you are the best

Thanks Professor

great video

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

NICE PROF...

So basically, the shape of the olive oil molecule prevents it from reaching the same low-energy state as butter molecules do. Could we use this in some way, to pull that energy out of the olive oil? This is the same question as zero-point energy, but at chemical scales instead of quantum scales.

Any exercises or rather exam questions

What is impact of cis and trans isomers on Boiling point of Fatty acids

@ProfessorDaveExplains

5 жыл бұрын

it's about the geometry, trans double bonds keep the chain in a straight line so they pack better, cis double bonds create a kink and screw up the lattice, so they melt lower. so trans fats are bad because they stay solid to higher temperatures and cause blockage in blood vessels.

I believe. Ads prevent this from playing 😢

are lipids technically polymers? Is it because of the isoprene unit?

Melting does not involve breaking any chemical bonds, it involves disrupting the lattice in which the molecules are organized. The video is correct.
