What effect does formaldehyde have on tissue?

Formaldehyde plays a crucial role in embalming due to its properties as a preservative. When applied to tissue, formaldehyde reacts with the proteins present in the cells through a process known as cross-linking. This process involves forming covalent bonds between protein molecules, which alters their structural integrity. As a result, the proteins are stabilized, preventing decomposition and effectively preserving the tissues for an extended period.

This ability to cross-link proteins is what makes formaldehyde such a vital agent in mortuary science. The stabilization of proteins helps maintain the physical appearance of the deceased, contributing to a more favorable presentation for viewing. Furthermore, because preserved tissues do not undergo the typical decay processes that would otherwise lead to deterioration, embalmers can achieve the desired results in terms of both presentation and longevity of the body during the time of viewing or memorial services.
