Sugar, Carbohydrates, & Acid in Apples
Simple Carbohydrates are often called "sugars" because they elicit varying levels of sweetness.
The carbohydrates contained in an apple are: fructose, glucose, and sucrose (glucose + fructose).
Glucose and fructose are monosaccharides; sucrose is a disaccharide.
Apples also contain carbohydrates called "fibres". Fibres are non-starch polysaccharides. The fibres contained in apples are:
