1. Who discovered Protein?Term coined in 1838; first sequence (insulin) determined in the 1950s
2. What is the amino acid composition?Proteins are polymers of 20 standard amino acids, with unique side chains
3. What is the structural hierarchy?Proteins fold through primary, secondary, tertiary, and sometimes quaternary structures
4. What are proteins and why are they important?Proteins are tiny building blocks made of amino acids that help your body grow, stay strong, and do many jobs like making muscles and fighting germs.
5. How do proteins get their shape?The order of amino acids tells the protein to fold into shapes like alpha‑helices and beta‑sheets, and then into a 3‑D shape that lets it do its job.

Peptide Bond: The covalent bond linking amino acids together in a polypeptide chain.
Chaperones: Proteins that assist in the proper folding of other proteins.
Proteostasis: The maintenance of a stable and functional proteome through regulation of protein synthesis, folding, and degradation.
