(Phys.org)—Diseases like mad cow disease or Alzheimer's are a result of protein mis-folding. Proteins are comprised of an amino acid chain that folds into a three-dimensional structure. According to the Anfinsen Principle, ...
In the beginning, there were simple chemicals. And they produced amino acids that eventually became the proteins necessary to create single cells. And the single cells became plants and animals. Recent research is revealing ...
