Never puts a single ad on any of his videos just so we could get what we need from them as quickly as possible and "move on with our lives".. truly the best
You are so clear in your explanations, the best i have seen by far on youtube. This is a great help for my MCAT Prep as I need to brush up on my content. Thank you so much!
for the longest i thought he was standing in front of a green screen 🤦♀️, until he erased something in his α helice and β sheet video LOL. Thank you AK for the thorough explanations and clear illustrations. I don't even know why I bought the biochem book, when I can just come here and watch you lecture about the topics.
thank you so much for the lectures I am so grateful for you work, I am studying for the mcat and you lectures are so much better than every thing I paid for thank you thank you thank you
Hello, I noticed a mistake in your explanation during class. In the video at 10.31, it was stated that hydrogen bonding breaks the ionic bond in NaCl, which is not correct according to the definition of hydrogen bond. Hydrogen bonding occurs when an atom covalently bonded to a highly electronegative atom is attracted to another electronegative atom with a lone pair of electrons. Therefore, the interaction between water molecules and dissolved ions should be called ion-dipole interaction, not hydrogen bonding. I wanted to bring this to your attention to ensure that the information being presented is accurate. Thank you."
No from the energy producing perspective the derivated energy producing system generates such condition of irrespective of all reaction generating the destruction of bonds.
@@AKLECTURES I learn Pharmacy in Turkish and I cannot understand lectures, I took the whole course from you God bless you Again Sir, I couldn't make it without you
Hi i am biology major student from Korea. I am studying biochemistry now with yours. thanks to advanced digital world, youtube and your effort so that i am able to listen your great lectures in such a long distance.:)
Hi! I first want to say your videos are great and very clear! So helpful, you are appreciated. I have a question on around 10:38 when you are speaking about the hydrophobic effect. You say that the hydrogens bonded to the sodium ion are hydrogen bonds but I thought hydrogen bonds, under definition, are when the hydrogen is bonded to one electronegative atom from one side (the hydrogen bond donor) and the acceptor also had to be an electronegative atom such as N, O, or F. Thank you!
A little late but, better late then never. According to what I learned in university you are right. Calling those hydrogen bonds was a slip up. They are another type of bond, I guess I would call the force Van Der Waals.
Very clear lectures, man. How I can measure my level of biochemistry, and how much is needed to begun manipulating the proceses in my body. Can I do it proper without understanding biology i chemistry?
Proteins (/ˈproʊˌtiːnz/ or /ˈproʊti.ᵻnz/) are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another.
Thank you so so much for the lectures which help me a lot to learn more about biochemistry. I'm a high school student and want to learn about biochemistry earlier so those playlists in your channel are really really helpful. Just wanna give you a suggestion to make a kind of worksheet or a test in form of pdf. that would be really cool and challenging. Once again thank you so much and have a good day!
Graet work man, this channel (especially this combination of videos) helped me a lot, thanks. how can I reach u for more information or to ask you some questions ?
I was wondering if it is because of the water properties that scientits say that there's no life without it in the universe. The NASA scientists got really excited when they found liquid water flowing in mars ( even though it was full of perchlorate). I am a chemistry student from Brazil and I just loved your class and your accent (which is very clear and easy to understand).
Please explain to me why do you call the linking bone between Na+ ang O in H2O is hydrogen bond ? Is it actually an ionic bond ? Thank you, i really enjoy the lecture.
Prior to 4:20 you speak of the water molecule as a oxygen atom ( elements of our reality calked the periodic table ) bonded together with two hydrogen atoms which keeps with electron orbital rules I would like to highlight this conversation with what you're describing the hydrogen is a smallest elementary particle that we observe under that premise let's look at it as trajectory with spin the known forces of the universe With the elementary periodic table describes is grand brane under the thought of string theory all elementary particles spin themselves into a brand with that implication hydrogen is our Master brane that all branes come from Let's see if anybody wants to comment
