Would you expect to find the following peptide sequence in a

Solution

Answer:- The reason being for example, amino acids such as Valine, Isoleucine, and Threonine all have branching at the beta carbon, this will cause steric clashes in an alpha helix arrangement. Glycine is the smallest amino acid and can fit into all structures so it does not favor the helix formation in particular. Therefore, these amino acids are mostly found where their side chains can fit nicely into the beta configuration.
