In the Sun's fusion sequence, about 0.007 kilograms of matter is converted into energy for each kilogram of hydrogen processed. In other words, the efficiency of mass-energy conversion is 0.7% and the amount of energy released is 0.007mc 2.

The common gamma chain is encoded by the gene IL-2 receptor gamma, or IL-2RÎ³, which is located on the X-chromosome. For this reason, immunodeficiency caused by mutations in IL-2RÎ³ is known as X-linked severe combined immunodeficiency. Most cases of SCID are due to mutations in the gene encoding the common gamma chain (Î³ c), a protein that is shared by the receptors for interleukins IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21. These interleukins and their receptors are involved in the development and differentiation of T and B cells.
