... humidity. She thought the A form was a potentially more interesting structure and wavered back and forth as to whether or not the A-form was helical, like the B-form clearly was. Franklin never received enough credit for her contributions.

how predict which aminoacid form secondary structure

... biopolymers such as proteins and nucleic acids. Secondary structure was predicted by using the programs PSIPRED and ALB. The residues predicted as helical are marked by H by PSIPRED and by H and & by ALB, and those predicted as -structural are marked by E by PSIPRED and by S and B by ALB.
