Starch
Starch is a plant storage carbohydrate made of linked glucose units.
Digestible starch is broken down into glucose, while some starch can resist digestion and behave as dietary fibre.
A glucose polymer
Starch is a chain of glucose units. Digestive enzymes can release those units for absorption, but starch structure, food matrix and preparation affect how quickly and how much becomes available.

Starch can be digested to Glucose
Digestible starch is broken down into glucose units that can be absorbed and used in metabolism.
Worth knowing
Some starch is resistant. EFSA includes resistant starch among non-digestible carbohydrates considered within dietary fibre when it meets the definition.
It has branched and unbranched forms. Amylose is mostly linear and amylopectin is branched; their structures affect how starch is arranged and digested.
A closer look
Preparation changes the matrix
Cooking and cooling can change starch structure and the proportion that resists digestion. Food structure therefore affects how much starch is available for absorption.
Digestion happens in stages
Digestive enzymes split digestible starch into smaller sugars before the small intestine absorbs glucose.
