Review Questions

• Explain the relationship between the butyryl group and the carboxylic acid butyric acid.
  • The butyryl group is derived from the four-carbon carboxylic acid, butyric acid. It is an acyl group with the formula CH3CH2CH2C(=O)-, which can be attached to various organic compounds, such as in the formation of butyryl-containing esters, amides, or nitriles. The butyryl group retains the four-carbon chain structure of butyric acid and is often used to name derivatives or functional group substitutions involving the original carboxylic acid.
• Describe how the butyryl group can be incorporated into nitrile compounds and the significance of this structural feature.
  • When a butyryl group is attached to a nitrile functional group, it forms a butyronitrile, which is a type of aliphatic nitrile. The presence of the butyryl group in a nitrile compound can influence its physical and chemical properties, such as its solubility, reactivity, and potential biological activities. Butyronitriles are used in various industrial applications, and the incorporation of the butyryl group can be an important structural feature in the synthesis and modification of nitrile-containing organic compounds.
• Analyze the role of the butyryl group in biological systems, particularly in the context of fatty acid metabolism.
  • In biological systems, the butyryl group is often found in the form of butyryl-CoA, which is an important intermediate in the β-oxidation pathway of fatty acid metabolism. Butyryl-CoA is produced during the breakdown of butyric acid, a short-chain fatty acid commonly found in butter and other dairy products. The presence of the butyryl group in this metabolic intermediate allows for its further conversion and utilization in energy-producing pathways, highlighting the significance of the butyryl group in the overall regulation and efficiency of cellular metabolism.
