Question

The most common monomer of carbohydrates is a molecule of
A)Glucose
B)Maltose
C)Amino acid
D)Phospholipid

Answer 1

Hint: This monomer of carbohydrate is mainly made by plants and most of the algae during the photosynthesis process It is also the most abundant monosaccharide. Plants usually make this to make cellulose in the cell walls.

Complete answer:
Carbohydrates are the polymers that are made up of monomers called a monosaccharide. The common monomers of carbohydrates are simple sugars like glucose and fructose. It is also one of the four basic macromolecules of life.
Monosaccharides - these are the simple sugars. Mono means one and saccharides mean sugar. The monosaccharide consists of usually 3 to 7 carbons. If sugar has an aldehyde group(R-CHO) then it is known as aldose. If sugar has a ketone group(RC(=O)R') then it is known as a ketose.
-The classification of monosaccharides is also dependent on the number of carbons in their sugar. When sugar consists of three carbons then it is known as trioses. Similarly five carbons (pentodes),six carbons(hexoses).
-Glucose is the most common monosaccharides and it is a very useful source of the energy.energy is released from the glucose and that energy is used to make adenosine triphosphate during cellular respiration.
-Plants also make glucose using carbon dioxide and water. This glucose is utilized by the plants for energy.

Additional Information:
Other common monosaccharides are galactose and fructose. Glucose and galactose are aldoses whereas fructose is a ketose sugar.
-Maltose - its common name is malt sugar and generally found in the germinating grains.it is also the intermediate between the hydrolysis of glycogen and starch. It consists mainly of two molecules of glucose in an α-(1,4) glycosidic linkage.
-Amino Acids -it forms the building block of a protein. 75% of the body comprises the amino acids. The amino acids involved in all body functions which includes growth and development, repair of damaged tissue, helps in the normal digestion, and also provide energy to the body.
Phospholipids - they regulate certain cellular processes and also consist of stabilizing and dynamic properties that can add advantage in drug delivery.
So, the correct answer is,” Glucose”.

Note: -So, glucose is the common monomer of carbohydrates. Carbohydrate helps in providing energy to the body mainly through glucose. Glucose is a simple sugar present in all the basic foods.
-The carbohydrate also comprises soluble and insoluble elements. Fiber is the insoluble part that removes excess cholesterol from the body and also regulates the rate of consumption of blood glucose.
