What would be the molecular formula of a monosaccharide characterized as an aldopentose?

Guida verificata passo dopo passo

Understand the term 'aldopentose': An aldopentose is a monosaccharide (simple sugar) that contains five carbon atoms (pentose) and an aldehyde functional group (-CHO).

Determine the general formula for monosaccharides: Monosaccharides follow the general formula

C_{n} H_{2 n} O_{n}

, where 'n' is the number of carbon atoms.

Apply the formula for a pentose: Since an aldopentose has five carbon atoms, substitute

n

= 5 into the general formula. This gives

C_{5} H_{10} O_{5}

Verify the presence of the aldehyde group: The molecular formula

C_{5} H_{10} O_{5}

is consistent with the structure of an aldopentose, which includes an aldehyde group and five carbon atoms.

Conclude that the molecular formula of an aldopentose is

C_{5} H_{10} O_{5}

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Monosaccharides

Monosaccharides are the simplest form of carbohydrates, consisting of single sugar molecules. They serve as the building blocks for more complex carbohydrates. Common examples include glucose and fructose, which are vital for energy production in living organisms.

Aldoses

Aldoses are a type of monosaccharide that contain an aldehyde group (-CHO) at one end of the molecule. This functional group is responsible for the reactivity and properties of aldoses, distinguishing them from ketoses, which contain a ketone group. Aldoses can participate in various biochemical reactions, including those involved in energy metabolism.

Pentoses

Pentoses are monosaccharides that contain five carbon atoms. They can be classified as either aldopentoses or ketopentoses, depending on the presence of an aldehyde or ketone group. Aldopentoses, such as ribose and arabinose, play crucial roles in biological processes, including the structure of nucleic acids.
