Molecule World Live

Molecule World brings interactive 3D molecular visualization to your Android phone or tablet. Open a structure from a file or fetch one by ID, then rotate, zoom, and explore it with a range of display styles, color schemes, and selection filters — whether you are teaching, studying, or just exploring the molecules of life. LOAD STRUCTURES - Open PDB, mmCIF, BinaryCIF (BCIF), MMDB JSON, and SDF/MOL files (gzipped supported) - Fetch any structure by its four-character PDB ID, downloaded as a biological assembly so large complexes still open quickly - Everything collects in a library, and the app reopens your last structure when you return DISPLAY STYLES - Ball & Stick, Spacefill, and Tubes (licorice) - Ribbon/cartoon with rounded helices and beta-sheet arrows - Molecular Surface, plus a Wire Surface that shows the shape while revealing what is underneath - Ligands, ions, and cofactors always read clearly — organics as element-colored sticks, metals as element-colored spheres — in every style COLOR SCHEMES Color by Element (CPK), Secondary structure, Chain, Rainbow (N to C terminus, 5' to 3'), Residue type, Residue, Charge, Hydrophobicity, B-factor, or Domain. Switching schemes is instant. FOCUS ON WHAT MATTERS Use Show to display the whole structure, add crystallographic water, or isolate proteins, nucleic acids, heterogens, or the backbone (core, complete, or C-alpha trace). Options that do not apply to a structure are dimmed automatically. SMART COLOR KEY A live legend shows exactly what the colors mean, filtered to what is actually on screen. Heterogens split into metals and non-metals, sugars use standard SNFG colors, and single-atom ions are labeled by element. DOMAINS Color by structural domain, with named antibody domains (VH, CH1, CH2, CH3, and light-chain domains) fetched from NCBI. Repeated chains collapse to a clean, unique set of colors. BUILT FOR MODERN STRUCTURES Design-pipeline models (RFdiffusion, RFantibody, and predicted structures) that ship without secondary-structure records still show proper sheets and helices — secondary structure is computed from the backbone when a file does not provide it. SHARE YOUR VIEW Capture a high-resolution snapshot with a transparent background, cropped tight to the structure, saved straight to your gallery. WHO IT'S FOR - Students and educators in biology, biochemistry, and chemistry exploring proteins, DNA, RNA, and small molecules - Structural biologists and crystallographers reviewing structures on the go - Antibody and protein engineers inspecting domains, design-pipeline models, and predicted models from moles like Alpha Fold - Anyone curious about the 3D shapes of the molecules of life Molecule World is developed by Digital World Biology. It is a companion to the macOS and iOS apps, bringing the same beautiful rendering and science to Android.
