Homework Statement
15) How is it possible that many different linear sequences of amino acids can form the same secondary structure (alpha helices, beta sheets, random coils, etc.)?
I understand that alpha-helices, beta-sheets, etc. appear in tons of proteins and peptides, but I do not understand why this is so. I know that the reason alpha-helices exist is due to hydrophobic amino acids being "protected" from water as well as hydrogen bonding between every fourth amino acid. However, I do not understand why they appear so often, as the common amino acids have such different properties. Please help!
Thank you
