01

Overview

The **casein phosphopeptide-amorphous calcium phosphate complex (CPP-ACP)** is a nano-sized aggregate formed from tryptic digestion of casein milk proteins, yielding phosphopeptides that stabilize calcium and phosphate ions in an amorphous, highly bioavailable structure[1][2][4]. CPP-ACP is used in dental and nutritional products to promote enamel remineralization and intestinal calcium absorption by preventing mineral precipitation and facilitating uptake[1][2][4][5]. While extensively studied for dental caries prevention and as a supplement for bone health, the complex is not a classical molecular target in drug discovery but a bioactive ingredient or delivery vehicle in food and dental science[5][7]. The composition, typically derived from bovine milk, makes it suitable for most populations, with research supporting its role in enhancing mineral bioavailability and remineralization processes in vivo[4][5][7].
