whoever is being mean, stop!!! LOL this woman is blessing us with her knowledge and all you guys can do is focus on the negative! you're awesome Jasmine!
I'm sorry, but I honestly think she explained it really well. You have a talent of explaining ma'am. Clear, concise, and short. Keep up the excellent work. And no, your voice is not as others have said, it's great! Thanks for helping me prep for my MCAT :D
I have been learning a lot about nutrition and how the body works so I can take better care of medical issues. Your videos fill a lot of missing pieces and are very understandable. Keep up the good work. Great voice!
These videos are amazing! They present the information with the perfect level of complexity and depth, and they are so incredibly thorough-they are an invaluable resource for me as a nutrition coach. And for the record, the narrator’s voice is lovely 😊
I sincerely hope you are a teacher because you are brilliant at it!!! Thank you so much for the generous time you spent doing this. I've subscribed and you will be my go to for all things biochem.
This video is amazing :). Thank you so much for taking the time to produce this video. I am fairly impressed by how you have simplified the information such that it is readily understandable by laymen like me. I always wondered how fat is digested in our body.
First of all you have an amazing voice, secondly the way you break it down it is so understandable and i am an engineer. Thank You very much you have been very helpful.
Omg it is soooo helpful thank you so much. I'm a French medical student and it helped me a lot understanding my lessons for my finals thank youuuuu! Btw, i love your voice!!!
Thank you very much. I had a very hard time understanding walls of scientific words on the internet, but this video is way easier to understand. You help me with my homework a real lot.
Great process summary. I have a question. When lecithin or Phosphatidylcholine is used as a carrier to encapsulate a nutrient, is the release of this nutrient triggered in the first encounter with the lipase molecule or in the second encounter with the lipoprotein lipase in the blood?
When medium chain fat is absorbed directly into the blood, does it go in as a triglyceride or is it broken down into fatty acids? The name of the MCT oil suggests that the trig. are entirely short, but natural substances like milk have mixed trig. and also work for quick energy delivery.
I find her voice soothing. Well organized and informative video. At 3:41 she says that, "our body secretes something called bile from the liver." This is incorrect. The bile is produced in the liver but stored and secreted from the gallbladder.
Are the FAs of the C2 on the glycerol backbone cleaved? I thought they were left on the glycerol backbone, and then absorbed, and then once inside the endothelial cells, repackaged? Also, before entering the blood, don't the chylomicrons go to the liver first? There were a few details of this video that I thought were misrepresented, but other than that, thank you so much for the video. The way you described everything was easy to understand.
Isn't it lipase only hydrolyzes the ester-bond in the carbons 1 and 3 of TAG? so the resulting products are 2 free fatty acids and a 2-monoacylglycerol? Just asking :) thanks for the vid though. its helping me a lot
-Thanks for the Great Explanation , But Doesnt the Pancreatic Lipase Cleave Ester bonds of C1 and C3 , and leaves Fatty acid of Carbon 2 unchanged ? And shouldnt Bile Salts Provide a Micelles for Transport of Fatty acids and Monoglycerol into the enterocyte ? . Thanks :)
Does this mean that all our consumed fats get absorbed and transported before reaching the large intestine? If they don't. What would cause this lack of absorption and are they just considered waste and excreted at that point? Your videos are incredibly informative by the way, I'm just extra curious
Ignore the ignorant comments from the guys who watch too much porn. Great video, very helpful, clear and concise with the right amount of detail. Nothing distracting or annoying about your voice.
Very nice presentation. However, the packaging of TAGs is not made inside a protein molecule. Instead, the TAG are surrounded by a phospholipid layer (purple circles). These phospholipids have polar head groups (phosphocholine) and hydrophobic tails (fatty acids). On this layer (facing the aqueous environment) several proteins are attached.
I am in the middle of viewing this video, and am thinking, "I really like this instructor." She explains everything clearly and concisely. I am also thinking, "Hmm, I really like the voice." I quickly check out some comments, and see that some have the opposite opinion. I am a guy, so I don't know, I really like this instructor's voice. Soothing, relaxing, but clear and bright at the same time. It's true that the voice alone can tell us whether we will like a person or not. For example, for me, when it comes to radio station hosts, generally speaking, the Jazz station hosts have the most pleasant and interesting voices.
Congratulation for the video, is very well done and really helped me, but I have a question: at 2:45 you've said "colesterol backbone" (or that's what I heard, if it's me, please excuse me for bothering you)...shouldn't it have been "glycerol backbone"?
Great content. But your voice is damn good ,maybe too good that it seems to bother certain other paracortical Areas other than hippocampus . other than that great work .hats off
This video missed digestion of medium chain and shorter fatty acids through the portal vein and is perhaps using a restricted definition of what is "fat".
I confuse this pathway with that of re-esterification😭 as the chylomicrons are transferred to the lacteals enter the lymphatics, not the portal vein😭😭 (in monogastrics)
*Some points you missed* Remember fatty acids dont simply diffuse into enterocytes in the intestine. They are absorped by *facilitated diffusion* , they are assisted by FABPs (fatty acid binding proteins) located at the enterocyte membrane. Another factor aiding the diffusion gradient/ translocation of fatty acids and monoacylglycerols from the micells and into the enterocyte is the rapid re-esterification of long-chain-fatty-acids into 2-MAG into triacylglycerols already happening inside the enterocyte (completed by the enzyme acyl-CoA-cholesterol acyltransferase, ACAT). Speaking of cholesterol, cholesterol also associates within micelles and are similarily absorbed by a different *sterol* -carrying protein in the enterocyte membrane. However much less cholesterol is absorbed this way (about 40% compared to 90% in fatty acids and MAGs), this is because cholesterol is reabsorped in the ileum together with bileacids in a salvaging hepatic circulation system designed for the liver to re-use cholesterol in the making of bileacid.
@@CitriReg What a strange comment. His videos are meant for education. It is only fitting for health professionals watching to add to the level of sophistication so that viewers can aid each other in learning the topics that are presented.
I really wanna huge u after seeing ur explanation cause I understand perfectly from u ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤😻 I'm going to complete this huge great explanation in the 2nd video 🚶♀️🚶♀️🚶♀️🚶♀️
