Carbohydrates, more commonly known as sugars, are made up of carbon, oxygen, and hydrogen atoms. The smallest unit of a carbohydrate is a monosaccharide. Two monosaccharides make up a disaccharide, and many monosaccharides make up a polysaccharide. Disaccharides and polysaccharides can be hydrolyzed back into the individual monosaccharide units. Part A Select the statement that is incorrect. View Available Hint(s) Select the statement that is incorrect. Complex sugars are carbohydrates. All carbohydrates have the general formula Cn(H2O)n. Simple sugars are carbohydrates. Carbohydrates contain only carbon, oxygen, and hydrogen atoms.

Monosaccharides are basic units (components) of carbohydrates. Those are simple sugars such as glucose, fructose, galactose. Two monosaccharides can join together via glycosylic bond and make disaccharides. Some of the disaccharides are: sucrose (glucose + fructose), lactose (galactose + glucose), maltose (glucose + glucose).

Disaccharides can be broken down to monosaccharides by an enzyme called a disaccharidase.

Longer chains of monosaccharides form oligosaccharides (usually as glycolipids ) and polysaccharides (starch, glycogen,cellulose, chitin).

Carbohyrates are important biomolecules included in metabolism, energy storage, they are also structural components, have role in immune response, as coenzymes etc.
