Biology Students Have Protein Folding Party
Alison Humphrey's Biology students are learning how proteins (polypeptides) form by bonding amino acids together. They show dehydration synthesis by squeezing water out when peptide bonds form. They also model primary (linear sequence of A.A), secondary (hydrogen bonds forming alpha/beta), tertiary (r-group interactions for overall protein folding), and quaternary structures (multiple proteins bonding such as hemoglobin). They also learned if the bonds break it changes the structure and function of the protein (ie. Sickle Cell Anemia).They also modeled that there are 20 different amino acids by wearing their party hats.
