Field notes
The practice interface asks learners to identify a structure by name, three-letter abbreviation, and side-chain group, with each answer field checked separately. It includes shuffle, restart, reveal, and next-structure controls, and says progress is saved in the browser. Its diagrams are described as charged forms based on a course handout; the page also notes that protonation can vary with pH.
