Exam Flashcards
What occurs in Autolysis
The body’s own enzymes begin to break down cells and tissue after death
When does autolysis start
immediately after death
Micromolecule decomposition contains which 3 components?
Proteins
Lipids
Carbohydrates
In Macromolecule decomposition the rate of breakdown is dependent on numerous factors such as ?
•temp
•microorganisms present
•health of individual
•composition of cells/tissues
What is Macromolecule decomposition?
When large molecules are broken down into smaller parts
Which enzymes have the capability to break down almost all macromolecules?
Hydrolytic enzymes
When does Protein Decomposition happen?
Starts when autolysis starts
What is the first step of protein decomposition
Autolysis
Once autolysis starts what else begins ?
protein decomposition
Which 2 tissues decompose at faster rates?
Epithelial tissue
Neuronal tissue
What is Proteolysis?
the process of breaking down proteins into smaller pieces
.
What are factors that influence POST MORTEM PROTEIN DECOMPOSITION?
•the age
•temperature
•insects
•body weight
What are factors that do not affect POSTMORTEM PROTEIN DECOMPOSITION?
Microorganisms
What are factors that partially influence POSTMORTEM PROTEIN DECOMPOSITION?
• cause of death
• exposure(weather)
• sex
what are micromolecules?
small molecules that are essential in building larger structures in living organisms
Examples of Micromolecules ?
fatty acids
amino acids
sugars
nucleotides
what is Adipocere
“grave wax”
grayish white wax substance that forms to cover a portion or all the body
Anaerobic
without oxygen
Aerobic
oxygen
Oxidation
substances loses electrons
something combines with oxygen or other chemail that steals its electrons
Hypoxic mean?
Low oxygen
Anoxic means ?
no oxygen
