Step 1

Alpha Helices	Beta Helices
Right-handed coiled rod-like structure.	Sheet-like structure.
Hydrogen bonds form within the polypeptide chain.	Beta sheets are reformed by linking two or more beta strands by H bonds.
Alpha helices can be a single chain.	Beta helices or Beta sheets can not exist as a single beta-strand.
Alpha helices have only one type.	Beta sheets can be parallel, anti-parallel, or mixed.
-R groups of the amino acids are oriented outside of the helix.	-R groups are directed to both inside and outside of the sheet.

In alpha-helices -CO group of a single amino acid is attached to the amino acid by an H-bond where polypeptide chains twisted into a spiral that is four down the chain and in a ß pleated sheet or beta helices, two or more polypeptide chains present next to each other, forming a sheet-like structure. This formation allows all amino acids present in the chain to forms hydrogen bonds with each other forming a wave.
