小狐生物实验室 vs PDB Viewer

小狐生物实验室是一款面向中学生、homeschool 家庭和科学进阶学习者的可视化生物学习 App。 App 不是静态百科，也不是刷题工具，而是把生物概念做成可以动手操作的互动实验。学生可以在模拟实验台中观察细胞结构、完成 DNA 碱基配对、理解身体系统中的物质流动，并通过食物网模拟观察生态系统的平衡变化。 首版包含多个互动模块： Cell Explorer 探索动物细胞和植物细胞，点选 nucleus、membrane、mitochondria、chloroplast 等结构，理解它们的功能和差异。 DNA Builder 通过 A-T、C-G 碱基配对规则完成互补链，理解 DNA、gene 和 trait 的基础关系。 Body System Flow 观察氧气、血液和营养物质在 respiratory、circulatory、digestive system 中的路径，理解人体系统如何协作。 Food Web Simulator 调节 producer、consumer 和 predator 的数量，观察能量流、种群变化和生态平衡。 Microscope Mode 模拟显微镜观察，调节放大倍数、焦距、光照和载玻片位置，理解显微观察中的视野变化。 小狐生物实验室属于 iFox Science Lab 系列，延续小狐物理实验室的可视化、交互式学习方式，让抽象科学概念更容易被看见、操作和理解。 Privacy Policy: http://mindkey.xyz/index.php/mindkey/privacy-policy/ Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

PDB Viewer turns your phone into a molecular microscope. Search the entire Protein Data Bank and over 200 million AlphaFold predictions, then explore any protein, virus, drug, or DNA structure in interactive 3D — free, with no account, no ads, and no sign-up. WHERE THE MOLECULES COME FROM • RCSB Protein Data Bank — 200,000+ experimentally determined structures • AlphaFold — 200M+ AI-predicted protein models • SWISS-MODEL — template-based homology models • PubChem and ChEMBL — millions of drugs and compounds • Crystallography Open Database — small-molecule crystals • NCI/CADD resolver — type a chemical name and get a 3D model Every source is free and needs no API key. You can also open your own .pdb and .cif files. WAYS TO SEE IT • Five representations: wireframe, ball-and-stick, space-filling (CPK), cartoon/ribbon, and a smooth molecular surface • Color by element, chain, secondary structure, rainbow, or AlphaFold confidence (pLDDT) • Biological assemblies: rebuild an entire icosahedral virus capsid from a few deposited chains • NMR ensembles: overlay every model in the bundle to watch a protein flex • Automatic secondary-structure detection MADE FOR TOUCH • Rotate, pinch-zoom, and pan with smooth native rendering • Tap any atom to see its element, residue, and chain • Recently viewed structures are cached, so they reopen instantly and work offline For students, researchers, teachers, and the simply curious. PDB Viewer makes structural biology beautiful and accessible. Structures are provided by their respective databases. PDB Viewer is independent and not affiliated with or endorsed by the RCSB PDB, EMBL-EBI, or AlphaFold.
