Qualitative tests for carbohydrates involve detecting the presence of specific functional groups or characteristics indicative of different types of carbohydrates. Here are some common qualitative tests for carbohydrates: 1. Benedict’s Test (Reducing Sugars) Principle: Detects reducing sugars that can reduce copper ions (Cu²⁺) to form a colored precipitate. Procedure: A …

Polysaccharides: chemical nature of starch and glycogen
Polysaccharides are complex carbohydrates composed of multiple monosaccharide units linked together through glycosidic bonds. These macromolecules can vary in size and structure, ranging from a few hundred to thousands of monosaccharide residues. Common examples of polysaccharides include starch, glycogen, and cellulose. Polysaccharides serve various functions in living organisms, such as …
Disaccharides: structure of maltose, lactose, and sucrose
Disaccharides, a type of carbohydrate, consist of two monosaccharide units linked together by a glycosidic bond. Monosaccharides, the building blocks for disaccharides, undergo a condensation reaction to form a disaccharide, eliminating a water molecule as the two monosaccharide units join together. Maltose Maltose is a disaccharide, a type of carbohydrate …
Monosaccharides: Structure of glucose, fructose, and galactose
Monosaccharides are the simplest form of carbohydrates, often called single sugars. They are the basic building blocks of more complex carbohydrates. Monosaccharides consist of a single sugar unit and cannot be further hydrolyzed to simpler compounds. The most common monosaccharides include glucose, fructose, and galactose, each with a specific molecular …
Carbohydrates: Definition, Classification, chemical properties
Carbohydrates are organic compounds of carbon, hydrogen, and oxygen atoms, typically with a hydrogen-oxygen atom ratio of 2:1 (as in water). They serve as a primary energy source for living organisms and play essential structural and functional roles in cells. Carbohydrates include sugars, starches, and fibers and can be classified …
