Explore two new interactive pathways: glycogen metabolism and fatty-acid β-oxidation. Glycolysis and the citric acid cycle now show the selected reaction above the full pathway, with clearer molecular structures. We’ve also refined translations and improved Full Access purchase and restore reliability.

We've improved the learning experience with clearer visuals, smoother navigation, and refinements throughout the app.

A major learning and curriculum update. • Expanded coverage of glycobiology, cell signaling, one-carbon and heme metabolism, and modern biochemical methods including mass spectrometry, cryo-EM, NMR, FRET, and proteomics. • Guided Learn has been substantially improved with more question-specific teaching and clearer concept-building before practice. • Added new scientific visuals to help explain molecular structures, pathways, organelles, and biochemical processes. • Expanded the course to 615 questions with stronger textbook-level coverage across the semester. • Improved scientific notation and terminology throughout the app. • Refined localization across all supported languages, including new learning and media content. • Additional accessibility, visual, and release-quality improvements.

This update refines lessons, practice, and interactive explorers, with improvements to accessibility, language support, and visual consistency throughout the app.

• A redesigned iPad experience built for the larger screen. • Guided Learn, Study Hub, pathways, graphs, and the Biochemistry Reference now use side-by-side layouts where they improve learning. • Additional interface, localization, and study-flow refinements throughout.

Biochemistry Tutor has been redesigned to make learning more guided and less repetitive. New Learn → Practice → Challenge study pathway, guided concept lessons, an expanded and refined bank of 600 biochemistry questions, improved question variety, visual exploration of structures, graphs and pathways, clearer molecular structures and scientific notation, improved mastery tracking, and expanded localization throughout the app.

This update brings major improvements across Biochemistry Tutor. The question bank has been expanded and refined with clearer wording, stronger topic coverage, and more varied conceptual and numerical practice. A new searchable Biochemistry Reference includes amino acids, key equations, cofactors, nucleic acids, and other high-yield study material, and can be opened while answering questions. Progress and Review tracking are now more accurate and persistent, with improved support for long-term retention. Accessibility has also been enhanced for graphs, biochemical pathways, and molecular structures, along with localization, interface, and reliability improvements.

This update introduces a clearer biochemistry course roadmap, featured practice topics, improved light and dark themes, streamlined settings, expanded language support, and more consistent quiz, review, help, and purchase screens.
