How is starch digested in humans

Dietary starches contribute as the largest energy sources by humans to meet their calorie intake. Starch is a complex macromolecule derived from plant-based foods and beverages.

Why is starch not digested in the stomach

Because of their structural complexity, starches seem to take a longer duration to get digested and used for energy needs. The gut employs several processes, such as mechanical and chemical, to degrade the complex conformation of starch into simpler molecules.

Starch digestion is a complex process involving enzymes like salivary and pancreatic amylase that break it down into smaller molecules.

These molecules, such as maltose, are further broken down by maltases and sucrases.

The resulting glucose is absorbed in the small intestine and transported to cells for energy or glycogen storage, playing a crucial role in providing a steady glucose supply for vital biological processes.

Starch and its Structure

Glucose is the functional unit of the starch molecule.

Repeating units of glucose molecules joined by glycosidic bonds compose a starch polymer. They undergo hydrolysis
