8
Q
coagulating
A
- embalming denatures protein cells by coagulating so that they can not be nutrient source for bacteria
- process of converting soluble proteins to insoluble protein by physical or chemical means
9
Q
denaturation
A
- when proteins or nucleic acids lose structure in their native state by applying some eternal stress or compounds such as a strong acid or base
10
Q
disinfectants
A
- in the group of aldehydes
- an agent, usually chemical, applied to inanimate/surfaces objects to kill most disease causing microbial agents, excluding bacterial spores
11
Q
embalming fluid functions
A
- Fixation of tissue and cells by cross linking nitrogen in proteins
- Act to denature cellular proteins of proteins so that they cannot be a nutrient source for bacteria
- Bacterial proteins are also denaturation in the process, thereby destroying the bacteria
