WebStarch is a polysaccharide composed of two types of polymers – amylose and amylopectin. Amylose constitutes 20-25% of the starch molecule. It is a linear chain consisting of repetitive glucose units linked by α-1, 4-glycosidic linkage. Amylopectin constitutes 75-80% of starch and is characterized by branched chains of glucose units. WebWe conducted screening of disaccharidase inhibition activity using various foodstuffs, and found that a boiling water extract of Mate leaf inhibited the sugar hydrolyzing activity. When maltose, sucrose, and starch were used as substrates, the IC50 values were 0.1, 0.5, and 0.6 mg/mL, respectively. fluid fitness studio https://bablito.com
