Single Choice
$$\alpha$$-1 Antitrypsin is _________________.
AAn antacid
BAn enzyme
CUsed to treat arthritis
DUsed to treat emphysema
Correct Answer
Solution
Disorder of $$\alpha$$-1-antitrypsin protein include $$\alpha$$-1 antitrypsin deficiency, an autosomal codominant hereditary disorder which leads to a chronic uninhabited tissue breakdown. This causes the degradation especially of lung tissue, and eventually leads to characteristic manifestations of pulmonary emphysema.
