Question

describe the classification of carbohydrates in long​

Answer 1

Answer:

Carbohydrates are divided into four types: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides consist of a simple sugar; that is, they have the chemical formula C6H12O6. Disaccharides are two simple sugars.

☆Carbohydrates:

• Carbohydrates are one of the three main classes of foods and a source of energy. Carbohydrates are mainly sugars and starches that the body breaks down into glucose (a simple sugar that the body can use to feed its cells).

☆Classification by

chemical:

•On the basis of the number of forming units, three major classes of carbohydrates can be defined: monosaccharides, oligosaccharides and polysaccharides.

• Monosaccharides or simply sugars are formed by only one polyhydroxy aldehydeidic or ketonic unit.The most abundant monosaccharide is D-glucose, also called dextrose.

• Oligosaccharides are formed by short chains of monosaccharidic units (from 2 to 20) linked one to the next by chemical bounds, called glycosidic bounds.The most abundant oligosaccharides are disaccharides, formed by two monosaccharides, and especially in the human diet the most important are sucrose (common table sugar), lactose and maltose. Within cells many oligosaccharides formed by three or more units do not find themselves as free molecules but linked to other ones, lipids or proteins, to form glycoconjugates.

• Polysaccharides are polymers consisting of 20 to 107 monosaccharidic units; they differ each other for the monosaccharides recurring in the structure, for the length and the degree of branching of chains or for the type of links between units.Whereas in the plant kingdom several types of polysaccharides are present, in vertebrates there are only a small number.Polysaccharides are defined

☆Classification by

Physiological:

•On the basis of their degree of polymerization, they can be classified as:

• simple: mono- and disaccharides (also known as “sugars”) and tri- and tetrasaccharides (oligosaccharides);

• complex: the polysaccharides.A further classification lays the foundations on the possibility of being used directly for energy

☆Carbohydrates:

• A carbohydrate  is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula Cm(H2O)n (where m may be different from n). However, not all carbohydrates conform to this precise stoichiometric definition (e.g., uronic acids, deoxy-sugars such as fucose), nor are all chemicals that do conform to this definition automatically classified as carbohydrates (e.g. formaldehyde).
