Digestion and Absorption of Carbohydrates

Transportation of squid ink polysaccharide SIP through intestinal epithelial cells and its utilization in the gastrointestinal tract

“…In the past years, people have vastly studied the digestion and absorption of carbohydrates. Hydrolysis in the luminal bulk fluid by secreted enzymes is the major pathway for the breakdown of polysaccharides to oligosaccharides, and further hydrolysis is accomplished by a battery of carbohydrases in the brush border of the mature enterocytes (Levin, 1994;Quezada-Calvillo & Nichols, 2009). In current opinions, dietary carbohydrates enter the intestine as monosaccharides (glucose, fructose, and galactose), disaccharides (lactose, sucrose, and maltose), or complex polysaccharides, and mostly transported as monosaccharides across the intestinal epithelium (Williams et al, 2011).…”
