1. The Forces Maintaining Protein Structure
... antiparallel and often twist to form structures such as a Beta barrel. Anti-parallel sheets are slightly stronger than parallel sheets, as the hydrogen bonds are planar and line up more efficiently to form more stable interactions. Turns are a common motif in proteins which allow a loop to form in the secondary structure. The most common type of turn is the beta turn which allows ... and prevents unwanted interference from water. Sequences of non-polar, core residues are commonly conserved between similar proteins as the residues must pack tightly to provide stability to the tertiary st...
