Amino acids, fatty acids, and ptomaines are examples of what?

• A. End products of decomposition
• B. Substrates for bacteria
• C. Inorganic compounds
• D. Proteins

Answer: (A)

Amino acids, fatty acids, and ptomaines are produced as a result of the breakdown of organic matter by bacteria. When proteins and fats decompose, they’re broken down into smaller molecules, with amino acids and fatty acids appearing as common end products. Ptomaines are a group of basic nitrogen-containing compounds formed from amino acids during putrefaction. Because these substances arise from the decomposition process itself, they are end products rather than substances bacteria use as starting materials, inorganic compounds, or intact proteins.
