Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is a carbohydrate containing two subunits?
A
disaccharide
B
diglyceride
C
dipeptide
D
base pair
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: -Carbohydrates can also be made up of two monomers called disaccharides. Some examples are lactose, which makes milk sweet; sucrose, which is your regular table sugar; and maltose, which is a product of starch breakdown. Each of these disaccharides is made up of two other monosaccharides.

Detailed explanation-3: -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).

Detailed explanation-4: -A disaccharide (also called a double sugar ) is the sugar formed when two monosaccharides (simple sugars) are joined by glycosidic linkage. Like monosaccharides, disaccharides are soluble in water. Three common examples are sucrose, lactose, and maltose.

Detailed explanation-5: -Monosaccharides are the simplest form of carbohydrates and are composed of a single molecule or subunit. The disaccharides are composed of two monosaccharides linked together, and polysaccharides are composed of 3 or more monosaccharides linked together.
