Monosaccharides are - Bbl6epure oAMH OTBer: a. glycogen b. galactose c. valine d. lactose

The correct answer is b. galactose.<br /><br />Monosaccharides are the simplest form of carbohydrates and are the building blocks of more complex carbohydrates. They are composed of a single sugar molecule and are the most basic form of sugar. Examples of monosaccharides include glucose, fructose, and galactose.<br /><br />Glycogen (option a) is a complex carbohydrate, specifically a polysaccharide, that serves as a form of energy storage in animals and fungi. It is not a monosaccharide.<br /><br />Valine (option c) is an essential amino acid, which is a building block of proteins. It is not a carbohydrate or a monosaccharide.<br /><br />Lactose (option d) is a disaccharide, which means it is composed of two monosaccharides, specifically glucose and galactose. It is the sugar found in milk and is not a monosaccharide.<br /><br />Therefore, the correct answer is b. galactose, as it is a monosaccharide.
