https://pages.htgaa.org/2026a/fiona-connolly/homework/week-04-hw-protein-design-part-i/index.htmlWeek 4 — Protein Design Part I Foundations of protein chemistry: alphabet, structure, and design A topic guide on the amino-acid alphabet, secondary structure, chirality, β-sheet aggregation, and the principles of designing structured peptides — written as a stand-alone primer rather than a homework Q&A. This page is Part A of the Week 4 deliverable for HTGAA Spring 2026; Parts B, C, and D (sequence/structure analysis, ML protein design, MS2 L-protein engineering proposal) will be added as those sessions complete.Hugoen
