Final answer:
The unpleasant flavors and odors caused by containing products of decomposed fatty acids refer to ketones, which are organic compounds characterized by a carbonyl group bonded to two carbon atoms. Some ketones have interesting properties and are used in various applications like butter flavoring, violet odor, musk oil, and insect repellents.
Step-by-step explanation:
The unpleasant flavors and odors caused by containing products of decomposed fatty acids refer to ketones. Ketones are organic compounds characterized by a carbonyl group (C=O) bonded to two carbon atoms. Some ketones, such as 2,3-butanedione, ß-ionone, muscone, and camphor, have interesting properties and are used in various applications like butter flavoring, violet odor, musk oil, and insect repellents.
