The Guide

Ten chapters, zero hand-waving

Each chapter builds on the last. Start at the beginning if you're new to biology, or jump in wherever curiosity strikes.

PART 01🧬

Proteins & Why They Matter

What proteins actually are, how they fold from a string of amino acids into precise 3-D machines, and what goes catastrophically wrong when they don't fold correctly.

PART 02🔬

The 50-Year Grand Challenge

Levinthal's paradox, energy landscapes, and why the world's sharpest biophysicists couldn't crack the protein folding problem for half a century.

AlphaFold's Origin Story

From CASP competitions and DeepMind's moonshot to the historic 2020 breakthrough that made structural biologists drop their jaws worldwide.

How AlphaFold Actually Works

The real technical meat: MSA, the Evoformer, attention mechanisms, triangular updates, and the structure module — all explained with intuition first.

Reading Confidence Scores

pLDDT colours, PAE heatmaps, and how to distinguish trustworthy predictions from model hallucinations — the skill that separates savvy users from naive ones.

Real Research Applications

Drug discovery, neglected diseases, the AlphaMissense variant classifier, antibiotic resistance, heat-tolerant crops, and plastic-eating enzymes — real impacts.

When to Use It (and When Not To)

Five critical limitations that even expert users get wrong — static snapshots, disordered regions, hallucination, and what AlphaFold fundamentally cannot tell you.

Beginner's Step-by-Step Guide

Find a sequence on UniProt, check the AlphaFold Database, run ColabFold, and visualise your result in Mol* — with common mistakes clearly flagged.

Going Deeper

AlphaFold-Multimer for complexes, AlphaFold 3's expanded biomolecule universe, molecular dynamics simulations, and open-source alternatives like ESMFold.

A curated reading list, essential papers with plain-English summaries, the best video tutorials, and communities where you can ask questions without fear.

Built for curious noobs,
not experts

Most resources about AlphaFold either oversimplify ("AI predicted protein shapes!") or assume a PhD in structural biology. This guide does neither.

Every technical term is explained from first principles — including the ones other guides just drop without explanation, like missense variants, intrinsically disordered regions, and co-evolutionary signals.

  • Every jargon term defined on first use
  • Intuitive analogies before mathematical formalism
  • Interactive diagrams for the tricky concepts
  • Light, warm, readable typography — no dark mode
  • Technically accurate throughout
