Key Concepts & Definitions

  • Biomacromolecule: Large organic molecules found in organisms, essential for structure and function.
  • Polymer: A large molecule composed of repeating smaller units called monomers.
  • Protein: A biomacromolecule made of amino acids, responsible for diverse functions such as catalysis, transport, and structural support.
  • Amino Acid: The building block of proteins, containing an amino group (NHβ‚‚), a carboxyl group (COOH), a hydrogen atom, and a variable R group attached to a central alpha carbon.
  • Peptide Bond: Covalent bond formed between the carboxyl group of one amino acid and the amino group of another during polymerization.
  • Protein Structure Levels: Primary (sequence), secondary (local folding), tertiary (3D shape), quaternary (assembly of multiple polypeptides).
