Glycine encephalopathy, which is also known as nonketotic hyperglycinemia or NKH, is a genetic disorder characterized by abnormally high levels of a molecule called glycine.bout 80 percent of cases of glycine encephalopathy result from mutations in the GLDC gene, while AMT mutations cause 10 percent to 15 percent of all cases. In a small percentage of affected individuals, the cause of this condition is unknown.
The Elements: 2009 y There are 91 naturally occurring elements (but it depends on how you count them). y The heaviest element that occurs in large quantity is uranium (atomic number 92). You can mine it like gold.
The heaviest naturally occurring element is uranium, which has 92 protons. Its most common form, or isotope, has 146 neutrons. Scientists have also artificially created most of the other elements between uranium and element 118. The newest element was created in a particle accelerator in Dubna, Russia, that shot a beam of calcium-48 ions (containing 20 protons) into a target of californium 249, an artificial element with 98 protons (map of Russia).
