Final answer:
The molecule described is a ketose. Thus the correct option is a) Ketose.
Step-by-step explanation:
This compound fits the description of a ketose due to the presence of a carbonyl group (C=O) at the second carbon position in a chain of carbon atoms. In a ketose, the functional group is a ketone, characterized by a carbon doubly bonded to an oxygen, while other carbons form a chain with hydrogen atoms. The structure provided indicates a ketose with three carbons (as it mentions a double-bonded C to O, with other carbons forming chains). The last carbon in this sequence is bonded to a hydrogen, concluding the presence of three carbons, fitting the definition of a triose.
The classification of sugars into ketoses and aldoses depends on the functional group present. Aldoses have an aldehyde functional group (C=O at the end of the carbon chain), while ketoses possess a ketone functional group (C=O within the carbon chain). In this molecule, the C=O is located within the carbon chain, not at the end, confirming its classification as a ketose. The naming and classification of sugars based on the functional groups they contain are fundamental in biochemistry and organic chemistry, determining their structure, properties, and biochemical roles.
Understanding the structure of organic compounds, especially carbohydrates, is crucial in biochemical processes such as metabolism and energy production. Recognizing the functional groups in sugars assists in comprehending their reactivity and biological functions. In this case, identifying the ketose structure aids in understanding its potential role in various biochemical pathways and its distinct properties compared to aldoses and other carbohydrate configurations. Thus the correct option is a) Ketose.
