Explain that since the atoms and molecules that make up sugar, salt, and alum are different, and have different charges, each substance has a different structure. They also, as a result, interact ...

All truncated molecules that are missing, say, the last building block, can be removed in a single washing step. In the end, the library has only those molecules that contain all the building ...

Note: Comparing the amount of temperature change for different substances by dissolving the same mass of each substance in the same amount of water is fine at the middle school level. However, a more ...

Many biologically important molecules change shape when stimulated by UV radiation. Although this property can also be found in some drugs, it is not yet well understood. Using an innovative ...

The method can also be applied to produce much larger drug molecules, such as ring-shaped peptides, which can be used to target additional pharmacological targets. Creating and testing all ...

Free radicals are unstable molecules that can damage cells and their DNA. Research suggests that they may play a role in many diseases, such as dementia, cardiovascular disease, and cancer.
