In fragmentation, the cells break down and die before they can proliferate and form new tissue. Regeneration, on the other hand, is when the cells divide and grow to replace the damaged tissue. Most of what we know about tissue regeneration comes from studies of animals, as human tissues regenerate much more slowly than those of other species.

For example, lines with m/z values 1 or 2 less than one of the easy lines are often due to loss of one or more hydrogen atoms during the fragmentation process. Example 16.10.2 16.10. 2: Pentan-3-one.
