## What is eProteins?

eProteins is an introductory digital book on proteins, from the Educational Technology Laboratory (LTE) of the Institute of Biology, University of Campinas (Unicamp, Brazil), for those who study or teach biochemistry. The book content is in Portuguese; the interface is also available in English and Spanish.

INTRODUCTION
• The 20 protein amino acids (plus the 21st and 22nd) in 3D, with one- and three-letter codes.
• Classification by side chain, with side-by-side comparison.
• D/L isomerism, charge and pH, and the peptide bond.

STRUCTURE
• The four levels of structure with real proteins in 3D: helices, sheets, GFP and hemoglobin.
• Denaturation: losing shape means losing function.

FUNCTION
• The functions of proteins.
• Diphtheria toxin as a model of structure and function, step by step.

QUIZ
• Amino acid codes, structures and 3D models, with random questions.

• Works offline on iPhone and iPad.
• No sign-up, no ads and no data collection.
