Structure Analysis

Secondary Structure
Predictor

Predict secondary structure elements (α-helix, β-sheet, turns, coils) using the Chou-Fasman algorithm with enhanced window-based scoring.

Amino Acid Sequence

0 aa

Try Examples

Chou-Fasman Method: Uses amino acid propensity values derived from known protein structures.

Higher helix propensity → α-helix
Higher sheet propensity → β-sheet
High turn propensity → Turn regions

Enter a Sequence

Input an amino acid sequence to predict
its secondary structure elements.
