Scientists develop novel method to monitor molecular aggregation

7 monthes ago   |   By Phys.org

Chiral molecules are defined as molecules that are non-superimposable on their mirror images, much like that of left and right human hand bone structure. There are many examples of chiral molecules in nature, including proteins and deoxyribonucleic acid. The dynamic processes of these chiral molecules are highly significant to understanding their biological activity. Indeed, protein aggregation is associated with many pathological conditions, including Alzheimer's disease, which is caused by the build-up of beta-amyloid fragments within the brain over time. Thus, it is important to...

Now a team of biologists from The University of Texas at Austin and the University of Michigan have invented a way to build synthetic structures from proteins, and just as in nature, the method is simple and could be used for a...
