Pentose is a five-carbon simple carbohydrate (monosaccharide
Monosaccharide
Monosaccharides, also called simple sugars, are the most basic units of carbohydrates. They are fundamental units of carbohydrates and cannot be further hydrolised to simpler compounds. The general formula is C nH 2nO n. They are the simplest form of sugar and are usually colorless, water-soluble,and crystalline solids. Some monosaccharides have a sweet taste.
