The type of bond that joins monosaccharides and is easily digested by enzymes in the human intestine is a __________. delta bond
timurjin [86]

Answer: alpha bond

Explanation:

The carbohydrates popularly called sugars are energy nutrients formed by carbon, hydrogen and oxygen atoms. It is the main energy source of the man and also has a structural or plastic role (formation of parts of cells such as the cell wall, or tissues, such as the exoskeleton chitin of the insects and crustaceans - crab). The small intestine's main mission is to complete the digestion of the chyme. In its passage through the duodenum, it suffers the action of pancreatic and intestinal juices and bile. In fact, it is in the duodenum that most digestive secretions are produced. The foods complexes are thus transformed into simple elements, easily assimilable by the body.

Enzymes are protein catalysts responsible for most of the chemical reactions of the organism, is found in all tissues. Amylase acts in the intestine hydrolyzing glucose polymers (starch, amylopectin, and glycogen). The bonds that hold the monosaccharides together and which are easily digested by pancreatic amylase in the intestine are known as alpha bonds. Some examples of sugars that have alpha bonds are sucrose, maltose, and starch.
