Scientists are diligently looking for other genes that may be involved in ALS, but currently, there is no other genetic test that will identify ALS in families. Therefore, the determination that an individual has the inherited type of ALS is typically based on family history rather than a genetic test.
Jakub Krystof Rad invented the first sugar cubes in the 1840s at a sugar refining plant in Dacice, a small Moravian town in what is now the Czech Republic. These early cubes were made primarily of beet sugar, and in modern times, either beet or cane sugar is considered acceptable.
The kind of sugar we usually think about - table sugar - is called sucrose. Sugar is made up of carbon, hydrogen and oxygen atoms. It's the way these atoms are connected that makes each type of carbohydrate different. In each molecule of table sugar there are: 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms. The black stuff is called burnt sugar! But seriously, this is what happens when you heat or burn things that contain carbon. It reacts with oxygen and oxidizes (burns).
