Here it's about the alpha helix, alpha helix and beta pleated sheet, beta pleated sheet.
00:16
So it's saying that these two represents which level of protein structure.
00:28
So whenever we talk about the protein structure, what we know it's showing primary, secondary, tertiary, primary, secondary, tertiary and quaternary structure.
00:38
So out of these four, this alpha helix and beta pleated sheet, they are showing secondary structure.
00:46
Secondary structure is what? here in the secondary structure of protein, this comes after the primary structure.
00:53
So first of all in the primary structure, there is a simple we can say sequence of amino acids.
01:02
So they are in the polypeptide chain, sequence in the polypeptide chain...
