Classification of carbohydrates video for grade 9
What are the classification of carbohydrates PDF?
Carbohydrates are classified into two main classes, sugars and polysaccharides. Sugars are sweet crystalline substances that are soluble in water.
What is the classification for carbohydrates?
How are carbohydrates classified? Carbohydrates are divided into four types: monosaccharides, disaccharides, oligosaccharides, and polysaccharides.
What are carbohydrates Class 9?
What are carbohydrates? Carbohydrates are biomolecules comprising carbon, hydrogen and oxygen atoms. They are an important source of energy. They are sugars, starch and fibres found in fruits and vegetables.
What are the classification of carbohydrates explain with examples?
They cannot be hydrolyzed into a simpler form. The simplest carbohydrates are the three-carbon dihydroxyacetone and trioses glyceraldehyde. They are further classified into glucose, fructose, galactose, and mannose.

What are the 4 main functions of carbohydrates?
They are energy production, energy storage, building macromolecules, sparing protein, and assisting in lipid metabolism.
What are the 3 types of carbohydrates and examples?
There are three main types of carbohydrates:
- Sugars. They are also called simple carbohydrates because they are in the most basic form. …
- Starches. They are complex carbohydrates, which are made of lots of simple sugars strung together. …
- Fiber. It is also a complex carbohydrate.
What are 10 examples of carbohydrates?
Carbohydrates are found in a wide array of both healthy and unhealthy foods—bread, beans, milk, popcorn, potatoes, cookies, spaghetti, soft drinks, corn, and cherry pie. They also come in a variety of forms. The most common and abundant forms are sugars, fibers, and starches.
What are carbohydrates and its classification and structure?
Carbohydrates are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides.
What are the 5 types of carbohydrates?
They are normally broken down into five major classifications of carbohydrates:
- Monosaccharides.
- Disaccharides.
- Oligosaccharides.
- Polysaccharides.
- Nucleotides.
What is the classification of monosaccharides?
Monosaccharides are also classified as aldoses or ketoses to indicate the carbonyl-containing group that is present. Those that contain an aldehyde functional group are called aldoses; those containing a ketone functional group on the second carbon atom are ketoses.
What are the classification of polysaccharides?
Polysaccharides can be broadly classified into two classes: Homo-polysaccharides – are made up of one type of monosaccharide units. ex: cellulose, starch, glycogen. Hetero-polysaccharides – are made up of two or more types of monosaccharide units.
How are carbohydrates classified list the sources and functions of carbohydrates?
Chemical classification of carbohydrates
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.
What is a carbohydrate simple definition?
: a substance (as a starch or sugar) that is rich in energy and is made up of carbon, hydrogen, and oxygen.
What are the functions of disaccharides?
What function do disaccharides serve in the body? Disaccharides act as an energy source for the body, just like any other carbohydrate. When we eat foods that contain disaccharides, our bodies break them down into simple sugars (monosaccharides) for absorption in the small intestine.
What is the structure characteristics and classification of carbohydrates?
Carbohydrate can be classified into three groups: monosaccharide, oligosaccharides and polysaccharides. Monosaccharide are the simplest carbohydrates which contain free aldehyde (-CHO) and ketone (>C=O) groups that have two or more hydroxyl (-OH) groups. The general formula of monosaccharide is Cn(H2O)n..
What is the structure and function of carbohydrates?
All carbohydrates contain molecules like glucose, fructose, cellulose, starch, glycoproteins, and chitin which are involved in several organismal functions. Their functions range from providing energy to the cells, supporting the structural integrity of cells, to supporting the organism’s growth and development.
What are polysaccharides function?
Functions Of Polysaccharides
The polysaccharides serve as a structural organization in animals and plants. Other functions of polysaccharides include: They store energy in organisms. Due to the presence of multiple hydrogen bonds, the water cannot invade the molecules making them hydrophobic.
What are the uses of polysaccharides?
Polysaccharides are used as demulcents, in drug formulations, for dental-impression materials, dusting powders, hemostatics, and for treatment of mild intestinal disorders. They are used for plasma replacement, and as anticoagulants both in solution and as surface treatment on artificial organs.
What is the function of monosaccharides?
The monosaccharide consists of single unit which contains carbon chain of three to six carbon. They can combine through glycosidic bonds to form larger carbohydrates. The main function of monosaccharide is to produce and store energy. Glucose and fructose are the most available monosaccharide in nature.
What is the main function of glycogen?
This stored form of glucose is made up of many connected glucose molecules and is called glycogen. When the body needs a quick boost of energy or when the body isn’t getting glucose from food, glycogen is broken down to release glucose into the bloodstream to be used as fuel for the cells.
Where is cellulose found?
1 Cellulose. Cellulose is the most abundant biopolymer, as it comprises the major structural component of the cell walls of lower and higher plants. We find high cellulose contents in stalks and stems and in other woody parts of plants.
Where is chitin found?
Chitin, which occurs in nature as ordered macrofibrils, is the major structural component in the exoskeletons of the crustaceans, crabs and shrimps, as well as the cell walls of fungi.
What is difference between glycogen and starch?
Starch is a storage form of energy in plants. It contains two polymers composed of glucose units: amylose (linear) and amylopectin (branched). Glycogen is a storage form of energy in animals. It is a branched polymer composed of glucose units.
