Quite a contrast between haemoglobinopathies and collagen. Did not expect this to be next. Nevertheless, I'm glad you're back to saving medical students in the heat of exams :)
He's back ya'll!!! Not even up to these classes yet but I clicked anyways!!! HE'S BACK!! I can't seem to understand my level of excitement. hahaha. Welcome back Mr !!! and thanks for all your help. so grateful
I am dyslexic and have past my exams in soft tissue therapy and I would like to thank you I still come back to your lectures to keep on learning and I am just blown away by your knowledge in all of your lectures .... thanks
hey I would like to say that I love your videos and they are very well made. I would like to add a correction to 02:18 where the 3 alpha helices actually do not form a triple alpha helix but a special helix called “collagen helix” (which is not an alpha helix). keep up the great work!
Hey, you have a massive mistake in your video. You are talking about alpha-helices all the time but collagen is not able form an alpha-helix (3 alpha-chains are forming a helical structure). all the best and greetings from Poland...your videos ale amazing :)
As far as I understand the 3 individual polypeptide chains form the 3 individual alpha-chains themselves. Then these 3 alpha-chains associate and intertwine to form a final triple stranded alpha helix. We call the collagen monomer a triple stranded alpha helix because the 3 alpha helices wind up in the alpha helix fashion. Hope it helps you!
@@NgocVu-hj8yg Collagen is rich in proline and glycine, both of which are important for the formation of the three-stranded helix. Proline facilitates the formation of the helical conformation of each α-chain, as its ring structure causes "kinks" in the peptide chain. Note: The presence of proline means that the helical conformation of the α-chain cannot be an α-helix. Hope this makes it understandable for you.
@@AKLECTURES please make new videos on physics and chemistry because the light is dull and board is not able see. And also make videos on ideal and non ideal gas and it's equation,graham law,dalton law of partial pressure, moosely law, hybridization theory and joule Thomson effect
