The alpha bonds of carbohydrates are broken down during digestion by specific enzymes. Lactose contains a beta bond, which is digestible by lactase. Most carbohydrates that contain beta-glycosidic bonds are not digestible because humans lack the enzyme needed to break down the bond. Which of the following carbohydrates contain alpha bonds that are digestible by humans? a) pectin and stachyoseb) cellulose and hemicellulosec) amylose and amylopectind) raffinose and beta-glucan

Amylose and Amylopectin  contain alpha bonds therefore, CAN BE DIGESTABLE BY HUMANS.
