 | | Under certain conditions, it is possible to produce a predominance of the beta form, in which regions that were alpha helical are now stabilized as beta pleated sheets. |
 | | The first condition is the predominance of genetically altered beta chains (HbS) in which the acid amino acid glutamate is replaced with the hydrophobic amino acid valine at amino acid position 6. |
 | | If beta forms were to encounter each other, however, there is the possibility that additional bonds would form, thereby stabilizing the molecules in the beta form. |
