Which of the following statements about monosaccharides is correct?

What is the most important monosaccharide from a biomedical point of view?

Which of the following statements about glucose is NOT true?

Isomers

Isomers are molecules with the same molecular formula but different arrangements of atoms in space.
Examples of isomers include glucose, fructose, galactose, and mannose, which have the same chemical formula C6H12O6.

Epimers

Epimers are sugars that differ in configuration at only one position.
They are a type of isomer.

Asymmetric Carbon

Asymmetric carbon, also known as chiral carbon, is a carbon atom linked to four different atoms or groups.
It is the farthest from the carbonyl carbon.

Monosaccharides

Monosaccharides are the simplest form of carbohydrates.
They contain only one sugar group and cannot be hydrolyzed to simpler forms.
Examples of monosaccharides include glucose, fructose, and galactose.
They can be classified based on the number of carbon atoms (e.g., triose, tetrose, pentose) and the presence of an aldehyde or ketone group (e.g., aldoses, ketoses).

Glucose

Glucose is the universal fuel for human cells.
It is an aldohexose, with an aldehyde group on C1, a hexose, and a polyhydroxy compound.
It has a primary alcohol group on the 6th carbon and a straight chain/open chain projection formula.

Importance of Glucose

From a biomedical point of view, glucose is the most important monosaccharide.
It is a crucial source of energy for human cells.
