Fittoniya [83]

<u>Chemical bonds between glucose molecules in starch that are easily broken by human </u><u>digestive enzymes </u><u>are called</u><u> alpha bonds.</u>

How is starch broken down into glucose?

  • When you consume starchy meals, an enzyme called amylase located in your saliva and small intestine breaks down the starches into sugars like glucose, maltotriose, and maltose.
  • Other enzymes, such as maltase, lactase, sucrase, and isomaltase, further break down these compound sugars into simple sugars.

What is alpha and beta bond?

  • The 1,4 alpha and 1,4 beta glycosidic linkages are the two different forms of glycosidic bonds.
  • When the OH on the carbon-1 is below the glucose ring, 1,4 alpha glycosidic bonds are created, whereas when the OH is above the plane, 1,4 beta glycosidic bonds are created.
