What is cellulose in food?
Cellulose is another polysaccharide commonly found in foods. Cellulose provides a protective covering and/or structure to fruits and vegetables and their seeds. It gives foods a crunchy texture and is undigestible in the body. However, cellulose does act as a source of dietary fiber, adding bulk to your stool and helping to maintain regular digestive processes. Many fruits and vegetables contain some aspect of cellulose, including in the skins of apples and pears, in the covering of whole grains like wheat bran and in plant leaves like spinach. Seeds and nuts also contain cellulose.
What is the prefix for carbohydrate?
Carbohydrates can be divided into several categories: monosaccharides, disaccharides and polysaccharides.

What are the three main types of polysaccharides?
Polysaccharides are long chains of monosaccharides linked by glycosidic bonds. Three important polysaccharides, starch, glycogen, and cellulose, are composed of glucose. Starch and glycogen serve as short-term energy stores in plants and animals, respectively. They range in structure from linear to highly branched. Polysaccharides are complex carbohydrates composed of ten or up to several thousand monosaccharides arranged in chains. Think of these as simple sugars linked by glycosidic bonds. When it comes to nutrition, polysaccharides play a huge role in the body. Polysaccharides have two roles: some, like starch or glycogen, help store the energy we gain from consuming food. Others help with cell structure. The most common monosaccharides in polysaccharides are glucose, fructose, galactose and mannose.
