Raffinose is a :
Raffinose is a :
- trisaccharide
- monosaccharide
- disaccharide
- none of the above
The Correct Option is A
Approach Solution - 1
Monosaccharides do not hydrolyse, disaccharides give two molecules of monosaccharides, trisaccharides give three molecules of monosacharides and polysaccharides give many molecules of monosaccharides on hydrolysis.
$\therefore$ Raffinose is trisaccharide.
$\underset{\text{raffinose}}{C_{18}H_{32}O_{16}} + H_2O \to$ glucose + fructose + galactose
Approach Solution -2
The Correct Answer is (A)
Real Life Applications
- Raffinose is a common component of beans, such as black beans, kidney beans, and lentils.
- Raffinose is also found in broccoli, Brussels sprouts, cabbage, and cauliflower.
- Raffinose is found in strawberries, raspberries, and blueberries.
- Raffinose is found in molasses, which is a byproduct of sugar production.

Concepts Used:
Carbohydrates
Carbohydrates, or carbs, are sugar molecules. Along with proteins and fats, carbohydrates are one of three main nutrients found in foods and drinks.
Your body breaks down carbohydrates into glucose. Glucose, or blood sugar, is the main source of energy for your body's cells, tissues, and organs. Glucose can be used immediately or stored in the liver and muscles for later use.
Classification of Carbohydrates
Carbohydrates are divided into two categories: simple and complex, based on their chemical structure and degree of polymerization.
Simple Carbohydrates (Monosaccharides, Disaccharides and Oligosaccharides)
One or two sugar molecules make up simple carbohydrates. Simple carbohydrates cause blood sugar levels to rise because molecules are easily digested and converted. Milk products, alcohol, vegetables, processed sugars, candies, and other foods contain a lot of them. These carbohydrates are referred to as "empty calories" because they lack fibre, vitamins, and minerals.
Complex Carbohydrates (Polysaccharides)
Starchy foods contain two or more sugar molecules and are thus referred to as complex carbohydrates. In comparison to simple carbohydrates, molecules in complex carbohydrates are digested and converted slowly. They are found in large quantities in potatoes, corn, cereals, lentils, peanuts, beans, whole-grain bread, peas, etc.
Carbohydrates can be found in the following examples:
- Glucose
- Galactose
- Maltose
- Fructose
- Sucrose
- Lactose
- Starch
- Cellulose
- Chitin
