Not to diss Crash Course (which I love and helped me passed General Bio with an A) but I think you're the best out there! You make it super easy to understand with examples and talk slowly and explain things! It makes me love biology so thank you for that! My first test is next monday and I've been preparing for a week now and these videos really are nifty, so thank you again!
I like Crash course, but these videos are much easier to understand. I also want to suggest the Amoeba Sisters. They make *really* fun bio videos, but they are more of overviews of the topics rather than in-depth lectures.
Thank you so much for posting this. I'm a single mom, business owner and college student and I was starting to fall apart in lecture today. I need this video. You are an angel.
I wish this guy was my teacher!! My AP Bio teacher has no idea how to explain things!! These videos are so useful and are the only reason I can kinda understend anything
wish I would have found this video before my Bio test. Great explaining and everything makes sense! My professor is amazing but this video gave it the extra kick i needed. Thanks!
i forgot some of the stuff that my teacher tought us for a midterm exam. In College Biology 141, very helpful to be readdressed. Thank you for the video.
This is a great review! I watched it before starting to study for the biochemistry ACS exam. It really helped me get back into biochemistry after a year off. Thanks!
You r superb i attend a lot of Supplementary classes but i find ur classes far better than those. Biology is cool but u make it more coooolerrr.................. keep up ur work
Great lecture. Suggestion: replace the white cursor with a red one. Also, replace the hand-drawn notation with graphics. Look forward to more of these.
1:25 I thought lipids aren't made of monomers at all. Another video says this about lipids: "...many do not consider lipids to have true monomers. This is due to the fact that their building blocks are made of two different substances (glycerol and fatty acids) that attach to each other--rather than attaching as one type of monomer to another. Also, due to the diversity of lipids, there are lipids that have a very different structure[s]..." Do lipids have a monomer or not?
The scientific community doesn't consider them monomers because they are really simple substances with basic structures. You will not find hundreds of chains of fatty acids attached to one glycerol, you only find three. Well yes, the fatty acids combine to the glycerol with dehydration synthesis, its technically not considered a polymer (which is made up of hundreds or thousands of monomers!!). I'm two years late and you probably have moved on from biology but I just dropped the information to anyone curious.
Great video, explained really clearly...but I'm pretty sure the picture you use of the steak is actually pork chops (which still have proteins so no harm no foul).
I am trying to help my niece with homework and I am perplexed with this chemistry question,What is the fourth class of biological macromolecules, that is not composed of monomers?
Satureted fats are the ones that´s not a fluid in room temperature, it´s a little confusing in this vid but a correction is done, if you view it properly.
