👉 Mortality fluid, also known as carcass fluid or putrescine, is a byproduct of protein degradation that occurs when tissues die and decompose. It's a complex mixture of nitrogenous compounds, including amino acids, their decay products, and other organic molecules. This fluid is highly toxic and contributes to the putrefactive process, causing the characteristic odors and signs of decay in dead organisms. While primarily associated with animal decomposition, similar processes occur in human tissues during advanced stages of decay or in certain medical contexts like organ preservation.
