Embalming Fluids and General
Chemistry Questions and Answers |
2025 LATEST UPDATED.
Aldehydes react with:
proteins.
Proteins are comprised of
amino acids.
Amino acids are associated with
nitrogen.
Methylene Bridge
a single carbon structure; in embalming, this is the product of the reaction of an aldehyde and protein
referred to as a "cross-link." Formed between two nitrogen atoms in two proteins and formaldehyde.
Methylene Bridge Results
Takes away a nutrient source for bacteria, Kills bacteria, Firms tissue at microscopic level.
Formaldehyde VS. Glutaraldehyde
Formaldehyde is a smaller molecule and is able to fit between proteins more easily. Formaldehyde will
link proteins at several sites along the chain. Glutaraldehyde will create the same methylene bridge but
is not as effective at creating them along multiple sites.
, Nitrogenous Waste
metabolic by-products such as urea and uric acid that contain nitrogen and tend to neutralize
formaldehyde. The presence of this will increase the preservative demand.
Preservative Demand
the amount of preservative necessary to properly embalm human remains.
Urotropin
the neutralization product of formaldehyde and ammonia.
Preservative Chemical Actions
Inactivation of chemical groups of proteins or amino acids, Inhibition of further decomposition,
inactivation of enzymes, Killing of microorganisms, Destruction of odors and elimination of further odor
production.
Arterial Fluid
concentrated preservative chemicals used primarily for arterial embalming. Functions primarily on
proteins in the body.
Cosmetic Fluid
arterial fluid that contains active dyes intended to restore a more natural skin tone. Non-cosmetic fluids
do not contain dye that stains tissues.
