For decades, the study of bioactive peptides—those small but potent molecules that defend, regulate, and heal within living systems—has been slowed not by a lack of data, but by a lack of integration. A research team at Zhejiang University has answered that fragmentation with PepAnno, a unified AI platform that predicts the biological functions of peptides by reading both their chemical sequence and their three-dimensional shape. In doing so, the platform does something rare in computational biology: it not only renders a verdict, but explains its reasoning, mapping the molecular features that
