The end result also creates the simulation, via color changes, of the appearance of blood flowing under the skin. Formaldehyde or glutaraldehyde fixes tissue or cells by irreversibly connecting a primary amine group in a protein molecule with a nearby nitrogen in a protein or DNA molecule through a -CH 2- linkage called a Schiff base.

The period for which a body is embalmed is dependent on time, expertise of the embalmer and factors regarding duration of stay and purpose.
