Question

Which of the following is not the example of carbohydrate?

• A. Fructose
• B. Glucose
• C. Glycine
• D. Maltose

Answer 1

The correct option is C

Glycine

Explanation for correct option

(C) Glycine

Carbohydrates

• Carbohydrates are a large group of naturally occurring organic compounds that are predominantly produced by plants.
• Cane sugar, glucose, and starch are examples of carbohydrates.
• They are categorized based on how they react to hydrolysis.
• They have been broadly classified into three groups.
• Monosaccharides, oligosaccharides, and polysaccharides are the three groups.

Glycine

• Glycine is not a carbohydrate, but rather a protein.
• They are organic molecules that are composed of long chains of amino acids.
• Proteins are present in many essential biological compounds such as enzymes.
• The structure of glycine is as follows:-
• 

Explanation for incorrect option

(A)

• Monsacchrides:-A carbohydrate that cannot be hydrolyzed further to give a simpler unit of polyhydroxy aldehyde or ketone is called a monosaccharide.
• Examples of monosaccharides are glucose and fructose.
• So, fructose is an example of carbohydrates.

(B)

• Glucose is an example of carbohydrates.

(C)

• Oligosacchrides:-Carbohydrates that yield two to ten monosaccharide units, on hydrolysis, are called oligosaccharides.
• An example of oligosaccharides is maltose.
• So, maltose is also a carbohydrate.
• Hence, options (A), (B), and (D) are incorrect.

Hence, option (C) is correct. Glycine is not an example of carbohydrates.
