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.
This makes the atomic weight of natural carbon 12.010. Carbon is the 19th most abundant element in the earth's crust, at 0.027%. It is found as carbon dioxide, carbonate rocks, and living matter. It occurs in elemental form in small amounts, as graphite and diamond. The properties of these forms of carbon, which are very important, are discussed in separate sections.
