Protein S is a vitamin K-dependent plasma glycoprotein synthesized in the liver and it functions as a cofactor to Protein C in the inactivation of Factors Va and VIIIa.
In the circulation, Protein S exists in two forms: a free form and a complex form bound to complement protein C4b. Only the free form has cofactor activity.
The gene (PROS1) is located on the third chromosome (3p11.1-q11.2).
Protein S deficiency is a rare blood disorder which can lead to an increased risk of thrombosis.

kg4uzj: @Noir_Musings The way I understand the science, the salt, through osmosis, pulls in the sugar which denatures the Protein slightly. |

iphonefresh: Done with blogs and some client updates. Will now plan a high carb / high Protein lunch. Fuel for my 100kms ride later today. Bit nervous :) |
