WebBeta sheets are formed when usually four or five (but sometimes up to 10) strands come together by hydrogen bonding. The Beta sheets can be completely anti-parallel, completely parallel, or a mixture of the two [8]. … Webβ -Sheets are formed by the interactions between parallel regions of a protein chain. These either run in the same direction, parallel; or in the opposite direction, antiparallel. These structures are stabilized by hydrogen bonds between backbone carbonyl oxygen atom and the hydrogen of the amino group.
