Oligosaccharides are complex carbohydrates that have 3 to 10 simple sugar units and cannot be broken down by the body's digestive enzymes. They are complex carbohydrates.
<h3>
Oligosaccharides, complex carbohydrates and enzymes</h3>
Oligosaccharides are complex carbohydrates composed of three or more monosaccharides (e.g., glucose and fructose) or the union of two or more disaccharides (e.g., lactose).
Humans cannot digest these oligosaccharides because we don't have digestive enzymes such as ⍺-galactosidase, thereby they cannot be hydrolyzed.
Complex carbohydrates are in turn long chains (either branched or unbranched) of monosaccharides linked by glycosidic bonds.
A well-known example of complex carbohydrates (polysaccharides) is starch, which is composed of many subunits of glucose.
Enzymes that break down complex carbohydrates must have the ability to break glycosidic bonds.
