What if a protein were more than just a string of amino acids? In this video, we begin our journey into the structure of proteins by decoding the primary and secondary levels. Why does the order of amino acids matter so much? And how does a simple chain twist into a helix? We’ll explore how proteins begin to take shape, from straight chains to spirals and folds, and why these early structures are crucial for everything that follows. Let’s untangle the basics and discover the elegant logic of biology, one level at a time! 00:00 - Introduction 00:50 - Translation oveview 01:43 - Primary level of protein 02:45 - Peptide bond 03:35 - The astronomical number of possibilities of proteins 05:18 - Secondary level of protein 06:11 - Alpha helix 07:11 - Beta- sheets 08:27 - Secondary are fibrous proteins Khan Academy India is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
