A disaccharide is a carbohydrate that contains ____
A
3 or more sugars
B
one sugar
C
two sugars
D
fatty acid chains
Explanation: 

Detailed explanation-1: -Disaccharides consist of two monosaccharide units, linked together with glycosidic bonds in the or orientation. The most important of them are sucrose, lactose, and maltose . Sucrose is the most abundant and consists of a molecule of -glucose and -fructose linked together (Figure 2(a)).

Detailed explanation-2: -disaccharide, also called double sugar, any substance that is composed of two molecules of simple sugars (monosaccharides) linked to each other. Disaccharides are crystalline water-soluble compounds.

Detailed explanation-3: -Disaccharides are sugars that are made up of two single sugar units joined together. Lactose, the main sugar found in milk, is a disaccharide, and it has a galactose and a glucose molecule. Table sugar, also known as sucrose, is extracted from sugar cane and is another example.

Detailed explanation-4: -Maltose, another common disaccharide, is composed of two glucose molecules.

Detailed explanation-5: -Disaccharides are comprised of two monosaccharides bonded together. The three naturally occurring disaccharides in human nutrition are sucrose (glucose bonded to fructose), lactose (glucose bonded to galactose), maltose (glucose bonded to glucose).
