In this lecture, EKG is going to cover protein structure, function, and regulation. First, we're going to break down the structure of amino acids. They are linked via covalent peptide bonds. Next, you'll learn about the four levels of organisation in the structure of a protein and how the specific shape of a protein determines its function in a cell. Third, how proteins fold in the most energetically favourable pathway and what happens if proteins fold incorrectly. Then, you'll learn how proteins work and how protein activity in the cell is controlled and regulated to maintain an optimal state.

This video was so helpful! I can’t believe this doesn’t have more views. Some of the best lectures I have found online.

[@EKGScience]

Thank you, Julianne! Glad to hear it was helpful 💙

This is a fantastic lecture. There is a minor correction on the ionized Amino acid form the Carboxylic group should be COO- without the H. Keep going your channel will grow. I am looking forward to see your lecture on Respiratory anatomy and physiology.

[@EKGScience]

Great catch! I forgot to remove the H when duplicating the drawing. Thank you for the support 🙏🏽
