Title : Chemical Structure of Sugars Previous topic PreviousNext Next topic

Our bodies can only absorb monosaccharides or single sugars, which are the smallest sugar units. Most sugars found naturally in foods or added to foods are disaccharides, or double sugars. During digestion disaccharides are broken down by digestive enzymes into the individual monosaccharides which can be absorbed by the body. Starches or complex carbohydrates are polysaccharides, which contain hundreds of single sugars. It usually takes longer for the body to break down complex carbohydrates into the monosaccharides or single sugars for absorption; however, they will be broken down.

Monosaccharides

Glucose
Fructose
Galactose

Disaccharides

Maltose = Glucose + Glucose
Sucrose = Glucose + Fructose
Lactose = Glucose + Galactose
