Chem 2, Unit 7 - Embalming Chemistry Flashcard

Front

What is the result of the cross-linking of proteins by formaldehyde?

Back

The tissue becomes firmer.

Front

What is formaldehyde or glutaraldehyde demand?

Back

The total amount of formaldehyde or glutaraldehyde needed to completely preserve proteins by using up any nitrogen residue.

Front

What is the main use of methyl alcohol in relation to formaldehyde?

Back

It is an effective antipolymerizing agent.

Front

What is the basis of cross-linking in the embalming process?

Back

The chemical reactivity of aldehydes with different forms of nitrogen.

Front

How do aldehyde-based preservatives inactivate enzymes?

Back

By neutralizing the enzymes when they unite with them.

Front

Define cross-linking in the context of embalming chemistry.

Back

Cross-linking refers to the process where formaldehyde reacts with proteins to form a stable network, enhancing tissue firmness.

Front

What role do aldehydes play in embalming?

Back

Aldehydes act as preservatives that cross-link proteins, preventing decomposition.

Front

Explain the term 'antipolymerizing agent' in embalming.

Back

An antipolymerizing agent prevents the polymerization of formaldehyde, ensuring it remains effective as a preservative.

Front

What is the significance of nitrogen in the embalming process?

Back

Nitrogen is a key component in proteins that reacts with aldehydes during cross-linking, essential for preservation.

Front

Describe the effect of formaldehyde on tissue hydration.

Back

Formaldehyde reduces tissue hydration by cross-linking proteins, leading to firmer tissues.
