PeptideCalc is a comprehensive peptide property calculation tool designed to provide researchers with fast and accurate analysis of peptide physicochemical properties. The features supported by this tool include:
General Physicochemical Property Calculation: Supports the calculation of key parameters such as peptide Molecular Weight, Isoelectric Point (pI), Net Charge at pH 7.4, Extinction Coefficients (205nm/214nm/280nm), and Hydrophobicity (LogP).
Aggregation Propensity Prediction: Based on the AggrePep Light model, it predicts the amyloid-forming propensity of peptides. This model was trained on a large dataset using machine learning and demonstrates excellent predictive performance (ROC AUC=0.88, Accuracy=80%), helping users evaluate peptide solubility and stability.
SMILES Generation: Supports the generation of SMILES strings for peptides, facilitating subsequent cheminformatics analysis.
pH-Charge Curve: Generates a curve showing the relationship between pH value and net charge, intuitively displaying the charge status of peptides under different pH environments.
Whether for single sequence analysis or batch processing, PeptideCalc can meet your needs.
