Vitamin C, vitamin E, and selenium are examples of substances that can prevent unwanted oxidation by neutralizing free radicals. Share Your Disco...
Shohini Gose quantum physicist says in her TED talk that quantum physics describes the behaviour of atoms and fundamental particles, like electrons or photons. A quantum computer operates by controlling the behaviour of these particles, which is very different from the way our traditional computers wo...
Viscosity describes the resistance of a liquid in flowing, informally described as the "thickness" of a fluid, and in principle, it has no direct relationship with density. However, the viscosity may influence the density determination depending on the method used. Measurements using: Pycn...
Glyca-binding proteins (GBPs)are a category of proteins that bind specifically to certain sugar molecules. The “glyca” is the same prefix you see in the wordglycation. That describes what happens after a protein or fat binds with a sugar molecule (3). ...
