Which is a basic unit of a sugar molecule?

monosaccharide
nucleotide
amino acid
fatty acid

Answer;

-Monosacharides

Explanation;

-Monosaccharides are the simplest form or classification of carbohydrates. They are hence known as the most basic unit of carbohydrates. They are defined as any carbohydrates (or sugars) that cannot be hydrolysed any further to give simpler sugars.

Monosaccharides are the building blocks of disaccharides such as sucrose, and polysaccharides such as starch and cellulose.

Two monosaccharides can be linked together to form a "double" sugar or disaccharide. Many monosaccharides link together to form polysaccharides.
