About the Program: PepDraw is a tool that was developed to facilitate the study of the chemical structure and properties of peptides. It allows users to draw the primary chemical structure of an amino acid sequence and predict some chemical properties such as mass, charge, and hydrophobicity. PepDraw was designed to be a powerful yet user-friendly tool for peptide analysis. It is especially useful for teaching students about the structure and properties of the amino acids.
The latest (and greatest) version of pepdraw is now on the web.
A sequence may be entered by typing directly into the sequence entry field or by clicking the buttons in the "Amino Acid Keypad." The program will only read characters that code for the 20 natural amino acids.
Properties are generated automatically upon changing the information in the sequence entry field.
