An enzyme named salivary amylase breaks starch into chunks of glucose called dextrins and maltose(disaccharide maltose). Once the food reaches the stomach‚ the acid in the stomach inactivates all salivary amylase. Carbohydrate digestion is not conducted the stomach for this reason.

Acinic cell carcinoma is believed to arise from progenitor reserve cells of the intercalated ducts of salivary tissue. Although characteristically slow growing with clinical behavior reflective of a low-grade tumor‚ acinic cell carcinoma can recur in 25—50% of patients if not treated adequately [Spafford et al‚ 1991]. A subset of acinic cell carcinomas are clinically more aggressive with metastasis to regional lymph nodes and distant sites‚ particularly the lung‚ at presentation. Histologic grading
