Answer: A. Cellulose glycogen galactose
Explanation
Cellulose, glycogen, and galactose are classic examples of carbohydrates belonging to specific groups. Cellulose and glycogen are complex polysaccharides, while galactose is a simple monosaccharide sugar. All these substances share the fundamental polyhydroxy aldehyde or ketone structural characteristics. Carbohydrates are broadly categorized into monosaccharides, oligosaccharides, and large polysaccharides. Galactose is a hexose monosaccharide found naturally in milk and various dairy products. Cellulose provides structural plant walls, and glycogen serves as animal energy storage polymers.
Dietary carbohydrates provide essential metabolic energy for cellular respiration in living organisms. Biochemical studies analyze polysaccharides to understand cellular recognition and energy metabolism. Food science relies on classifying carbohydrates to determine nutritional values and digestibility. Glyceraldehydes glucose peptone mixes a protein fragment with sugars, making it an invalid set. Glycerol phospholipids collagen includes lipids and structural proteins rather than pure carbohydrates. Legumin amylopectin albumin contains storage proteins alongside starch polysaccharides, violating the category.
