About this app
Learn all 20 standard amino acids and build the recall you need for biochemistry, biology, organic chemistry, and MCAT preparation. Study names, structures, properties, codes, codons, polarity, charge, essentiality, pKa values, molar mass, biological roles, and helpful mnemonics. LEARN AT YOUR OWN PACE Explore detailed profiles for every standard amino acid. Search and filter the collection, compare properties, and review clear structural formulas. PRACTICE ACTIVE RECALL Test yourself with: • Multiple-choice questions • Typed answers • Topic-focused practice • Mixed exams • Timed speed rounds • Structure completion exercises • Review of previous mistakes COMPLETE CHEMICAL STRUCTURES Practice molecular recognition by filling missing atoms and functional groups directly into amino acid structures. Immediate visual feedback shows which answers are correct and which need another attempt. BUILD LONG-TERM MEMORY Spaced review brings amino acids and topics back when they are ready to be reinforced. Daily goals, streaks, mastery levels, achievements, and session history help you follow your progress. FOCUSED AND PRIVATE • All 20 amino acids are available immediately • No advertisements • No account required • Works entirely offline • Progress stays on your device Whether you are beginning biochemistry or preparing for an exam, this app provides a focused way to learn amino acids through study, recall, and repetition.
