• Zwitterions
• Isoelectric point
• Peptide bonds
• Protein structure (1°, 2°, 3°, 4°)
• Denaturation

How Amino Acids and Proteins Is Tested

MDCAT questions on Amino Acids and Proteins are a mix of recall (definitions, classifications), application (predict outcomes, interpret diagrams), and basic numerical/analytical reasoning. PMDC papers from 2020–2025 emphasized the concepts above; older UHS papers (2008–2019) tested them too, with slight variations in question framing.
