Protein Keywords
amino acids – the monomers from which proteins are made from dipeptide – 2 amino acids joined together with 1 peptide bond polypeptide – Many amino acids joined together with peptide bonds primary structure]] – first structure of a protein. Chain of amino acids + order secondary structure – second structure of a protein. α-helix and β-pleated sheet tertiary structure – third structure of a protein. Folding of α-helix and β-pleated sheet into 3D structure quaternary structure – joining of tertiary structure proteins together into larger molecules enzyme – a protein molecule able to catalyse the break down / formation of molecules induced-fit model – the theory stating that the enzyme’s active site changes shape slightly when a substrate attaches lock and key model – the theory stating that the enzyme’s active site is rigid and never changes shape
