Document Summary

Chiral molecules: these are molecules that have the same chemical make up and connectivity but different orientation. Rosaline franklin: found through the tobacco mosaic virus that some constituent molecules are able to automatically recognize each other and reform back into the virus form self- assembly. With this info, scientists are now developing bioactive molecules called peptide amphiphiles where it becomes a putty-material that will be able to help regenerate bone growth and repair fractures. 9. 2: experimental tools for molecular structures and shapes. Characteristic behaviors/properties of a compound are given through the connectivity, spatial arrangements, and overall shape. Mass spectrometer: decomposes the compound into fragments so you can be provided with some info on how the atoms were connected. Infrared spectrum: tells you what functional group is attached to the carbons. Polarimetry: shows us the difference between isomeric substances that have the same connectivity but different configuration (3-d orientation in space) These techniques allow us to discover the molecular formulas, func.
