4. Enzymes & Metabolism
MIT OpenCourseWare・2 minutes read
Today's lesson covers proteins, amino acids, and peptides, focusing on a protein variant causing sickle cell anemia, with genetic mutations affecting protein structure and function. Enzymes act as catalysts, manipulating reactions by lowering activation energy and impacting the energetics of transformations.
Insights
- A single genetic mutation in the beta globin gene on chromosome 11 leads to sickle cell anemia by changing glutamic acid to valine, resulting in the sickling of red blood cells.
- Enzymes, as proteins, act as catalysts in reactions by lowering the energy of activation, enabling changes and transformations at room temperature, and manipulating the energetics of reactions to facilitate various processes.
