Shortness of breath: Alpha 1 antitrypsin (aat) is a molecule in the blood and alveolar space. This naturally occuring molecule is protecting alveolar walls from breaking by trypsin which is also naturally occuring molecule during lipid metabolism of the cells. Trypsin is causing oxidative damage to the cells and needs to be scavenged. Aat deficiency is a genetic disorder with abnormal production of the aat molecule.
