Your free peptide-science learning path
Start with the building blocks, connect structure to function, then learn to question a research claim. Follow the six guides in order or return to the step you need.
Prepared with AI-assisted drafting and editorial source checking. Author and clarity-review credits are not independent scientific review. No college credit, professional certification or university endorsement is implied. How scientific review will be recorded.
No account, enrollment or payment required. This suggested route does not award a degree, college credit or a professional credential.
Amino acids and acid–base chemistry
Recognize amino-acid building blocks and explain charge and pH.
The peptide bond and protein structure
Explain peptide bonds and distinguish the four levels of structure.
Protein folding and stability
Connect sequence, shape and the limits of structural models.
Enzymes and kinetics
Interpret reaction rates and distinguish inhibition models.
Studying proteins and peptides in the lab
Ask what an experimental method actually measures.
Peptide hormones and signaling
Separate a biological mechanism from evidence for a medicine.
Then put the science into context
Read how evidence levels work, then choose a research branch. The existing level labels suggest depth; they are not accredited academic classifications or entry requirements.
Host defense, antimicrobial peptides & biofilms
Start with the antimicrobial introductionUnderstand biofilm measurementsEvaluate the LL-37 case studyProtein folding & experimental cancer research
Evaluate the CT20p case studyRead the CT20p profileExplore the wider curriculumFinish with a claim-checking exercise
Choose one profile and write down the claim, experimental model, comparison group, measured outcome and main limitation. State what the study does not establish. Use the linked original reading to support your answer; this is ungraded practice.
