Phosphorylation of a Kinase

9/11/08

Most phosphates are located throughout the body by way of ATP (adenosine triphosphate). ATP is avaliable in every cell and contains three phosphate groups. A kinase will take one phosphate group from ATP, making the previous ATP into ADP (adenosine diphosphate). It will take this phosphate and phosphorylate (or add a phosphate) to its target. The added phosphate will change the structure and therefore the function of the target.

How do stem cells work?
Stem cells are neutral cells that can differentiate into other types of cells. They are found throughout the body and are able to replicate when needed to do so. In embryonic tissue, stem cells are used to create new tissues from specialized cells in order to further the growing process. In adults, stem cells are used to regenerate lost cells by replacing the dead or old ones with new cells, such as skin.
