Embalming Theory III - Chapter 18: Amines and Amides

Organic derivatives of ammonia in which one or more of the three hydrogens of NH3 have been replaced by alkyl (R) or aromatic groups:

Amines

Like alcohols, _______ may be designated as primary, secondary, or tertiary according to the position of attachment of the nitrogen

Amines

General formula of Amines:

R-NH2

Characterized by a strong fish-like odor:

Amines

Produced as products of proteins and other nitrogenous animal and plant substances:

Amines

We refer to these as intermediate products of decomposition:

Amines

Also commonly called ptomaines:

Amines

From the Greek ptoma, meaning:

"Corpse"

Two examples of ptomaines:

- Putrescine

- Cadaverine

Both ammonia and its derivative substances, the amines, are basic due to the:

Presence of an unshared pair of electrons

Both ammonia and its derivative substances, the amines, are basic due to the presence of an unshared pair of electrons because of this _____________ that bodies with an excessive build-up of amines or other nitrogenous waste products will neutralize formaldehyde

Alkalinity

Produced when amines react with carboxylic acids:

Amides

Are an ammonium salt:

Amides

Named by replacing the -ic suffix of the reacting acid with -amide:

Amides

Waste product of human protein metabolism secreted into the blood of the liver and selectively absorbed and excreted into the urine by the kidneys:

Urea

When all hydrogens of an amine have been replaced with a hydrogen ion, an alkyl group or an aromatic group ____________________________ is formed

Quaternary ammonium ion

Have detergent and disinfectant properties:

Some quaternary ammonium salts

Will render any alkaline substance useless:

Soap

Reaction between the cation of a quat and the negative ion of soap molecules produces an _______________, thus removing the quat from the solution

Insoluble salt
