[@Ch3coohhco]

amazing i really now understand the protein structure it was so complicated but now it is so easy

[@Gottacrisis]

Brilliant Job! Greetings from the UK

[@caueapg5189]

[@aliabdul6500]

Very useful, thank you for your efforts, much appreciated.

[@regineyo6028]

thank you so much for the two videos on Proteins!! But I believe it would be better if the parts on alpha helix and beta pleated were elaborated further. thank you :)

[@AnnaJean14]

Thanks so much! It all makes sense now! Helped me for my midterms! Thanks :)

[@bloodpainter626]

How lovely it will be if you ware our teacher ! Thank you miss ^^

Best teaching

[@jaderoza]

Great, clear explanation !

[@macdufal]

Thank you so much for helping me to understand these key concepts!

[@beautybook7]

Why can't University professors make it understandable just like you did. We spend 2 days on this subject and I understood it all in 11 minutes with your video.

[@عبداللهعبدالله-ط4م1ض]

Hello Dr.krstina Thank you the lectuer very good about structuar proteind and explain structuar amino acid ..... Sincerely

[@eyes21st]

Really great work, seen some of your other video’s & they are excellent too. Keep up the good work!

[@youngchase3636]

Simply Phenominal!!

[@sihamabdilahi1339]

thnks you are really amazing teacher👍

[@sangeenkhan2430]

Amino acids starts folding at secondary level. In primary it just makes peptide bonds. Dont be confused

[@sailiscriviner5411]

Nicely explained.

[@mohammedalmsleh7217]

Thank you simple and very useful

[@AbsoluteDegens]

are the variable groups always positioned at the bottom of the structure as shown? ie is this a reliable way of identifying the variable group if not displaying the R symbol

[@NicolesKeys]

awesome video!! so helpful.

[@BalaBiologyWorld]

nice video maam.....

[@ditasucimulia9784]

Thank you so much . I can understand from this video

[@imagination7710]

My guess for the amino acids at 3:43 - top right = glycine, bottom right = tyrosine, middle = cysteine and bottom left = leucine

[@undeadda]

This is awesome! Thanks for posting!

[@rawanreda6908]

You're spectacular! Great video!!

[@IrfanKhan-rd2tg]

mashala so nice .

[@irinabains4300]

amazing video, just needed clarification on: so the entire polypeptide chain (primary structure) doesn't fold into either of the secondary structures? So, certain segments of the chain just stay unfolded while the others fold into secondary structures?

[@kristinagremski]

Thank you. :). This video was simplified, since it was intended for high school students in AP Biology. There are other types of secondary structures, as well as segments of the polypeptide chain fold into shapes that don't have a specific name. This website explains pretty well: www.cryst.bbk.ac.uk/PPS2/course/section8/ss-960531_4.html

[@irinabains4300]

@@kristinagremski Thank you! The link was indeed helpful but just want to once again clarify this, so the entire linear polypeptide chain which is the primary structure is folded into one or the other secondary structures right? No segment of the primary structure is left unfolded, I believe.

[@laiaplaiap1688]

Thank you very much doctor 💛

[@blooee1989]

A great explanation, thanks

[@ritanjalipatel7180]

[@ShyamSundar-nm2dm]

Thank u mam have any video on blood coagulation.

[@nguyenduythuan1]

perfect lesson,

[@kristinagremski]

No, I'm sorry. I don't write the text out; I improvise it based on the types of explanations that have helped my students in the past. Thank you for your compliment though!

[@owensiamalala4283]

well explained i like it.
