Amino Acids 3D

Learn the 20 standard amino acids the way you actually need to know them: their 3D shapes, their structural formulas, their chemical properties, and the real history behind their discovery — not just a list of names to memorize. FLASHCARDS Flip through all 20 amino acids with a rotatable, interactive 3D ball-and-stick model on the front. Drag to rotate, and toggle between the zwitterion (physiological pH) and neutral forms to see exactly how the charge changes. Flip the card for full details: category, charge, side chain formula, molecular weight, isoelectric point, essential/nonessential status, and a 2D structural formula with the side chain highlighted. Filter by structural category (nonpolar, aromatic, polar uncharged, acidic, basic) to focus your review. QUIZ — 7 MODES - Identify the Model: name the amino acid from its rotating 3D structure - Identify the Skeleton: name it from its…
