Descrizione generale
Molecular mass: 51-54 kDa.
α-Amylase isolated from porcine pancreas is a glycoprotein. It is a single polypeptide chain of ~475 residues containing two SH groups and four disulfide bridges and a tightly bound Ca2+ necessary for stability. Chloride ions are necessary for activity and stability. The pH range for activity is 5.5 to 8.0, with the pH optimum at 7.

Altered monoamine neurotransmission accompanied by hypothalamic-pituitary-adrenal axis dysfunction and autonomic nervous system hyperactivity have been associated with major depressive disorder (MDD). Salivary α-amylase (sAA) is indicative of autonomic activation and reflects central noradrenergic activity. Scarce studies on sAA in MDD
