Antithrombin III
Antithrombin III (AT III) is a glycoprotein and member of serpin super family protein .AT III inactivates more than a few enzymes of the blood coagulation system in Homo sapiens .The AT III gene on chromosome 1 encodes a glycoprotein of approximately 58 KDa MW .AT III is having 432 amino acids length with a single chain glycoprotein and 3 disulfide bridges and 4 carbohydrate side chains that report for 15% of the total mass .AT III also act as a mediator of heparin's anticoagulant activity with two to three days of biological half life [139]. Alfa AT III is also the most important form of AT III originated in blood plasma and has an oligosaccharide occupying each of its four glycosylation sites. A single glycosylation site remains always

    Deep Vein Thrombosis

    • 628 Words
    • 3 Pages

    A hospitalization for a deep vein thrombosis (DVT) is a serious matter and can be life threatening. DVT is a venous obstruction caused by incompetent valves. This is treated extremely aggressively due to the potential for it to cause embolization to the pulmonary circulation. Patient T.V. has recently had abdominal surgery and is now in the hospital to treat DVT in her left leg. After the third day she begins having shortness of breath and supplemental oxygen is needed. Considering T.V.’s history and her recent abdominal surgery, she is most likely experiencing respiratory distress due to pulmonary emboli. DVT is the most frequent source of pulmonary emboli, which is a blockage in the main artery of the lung. Pulmonary embolism is usually caused by thrombi that are dislodged from the leg veins or the pelvis, but they most commonly arise in the deep veins of the legs. There are a number of predisposing factors that might cause a pulmonary embolism. In T.V.’s case, it was most likely due to her recent surgery since there is not enough evidence given to determine if there is another predisposing factors.…

    The purpose of this experiment was to identify four synthetic blood samples through a process called blood typing. According to Fredrick H. Martin, PhD., et.al, blood typing is a test that determines a person’s blood type by checking the blood for the presence or absence of specific glycoprotein called antigens found on the surface of the red blood cells. The two clinically relevant antigens are the A antigen and B antigen. The blood type is named based upon which antigen is present on the surface of its red blood cells. There are four blood types. Blood type A has A antigens; blood type B has B antigens; blood type AB has both A and B antigens and blood type O has neither A nor B antigens on the surface of the red blood cells. An additional…
