| We have discussed the four different types of biological molecules, and we have also discussed the importance of buffers. The buffering system in blood is most important to what specific type of organic molecule? Why? |
|
Definition
4 types=carbohydrates, lipids. Proteins, nucleic acids
importance of buffers=to maintain a particular pH (7.4 in blood)
Enzymes, a type of protein, must maintain a specific three-dimensional shape. Excess hydrogen ions or hydroxide ions will change the shape of enzymes making them non-functional (denatured). |
