SUMMARY

Deuterium oxide (D2O), commonly known as heavy water, interacts with biological systems differently than regular water (H2O). The bonds involving deuterium are stronger, resulting in slower molecular vibrations and consequently slower biochemical reactions. While bacteria can survive in heavy water, mammals face fatal consequences with high concentrations, potentially lethal at around 25% of body weight. Understanding these interactions is crucial for comprehending the biochemical implications of heavy water on living organisms.

PREREQUISITES
  • Understanding of molecular bonding and atomic structure
  • Basic knowledge of biochemical processes in living organisms
  • Familiarity with the concept of isotopes, specifically deuterium

This may seem like a pretty broad question, but ill try and narrow it down the best I can.

Lets say, Me, or a insect, drink some Deuteriuim oxide (under the leathal dose).

How does it(d20, deuterium oxide)) interact without bodies, and what does it do to our bodies compared to regular water (H2o) ?

Basically, bonds involving deuterium can be of a different strength than bonds with hydrogen-1, and since vibrations are slower with a heavier atom, chemical reactions are slowed down. This messes up some biochemical processes which are very fine tuned to work with normal water. For bacteria, they are slowed down but are still able to live and reproduce. In mammals, a large change in the concentration of D20 is fatal. It would take a very high amount of heavy water to kill someone, around a quarter of the weight of their entire body, but it is possible in principle.
 
So bassicaly we have heavy water, which is Deuterium connecting to oxygen...and normal water, which is Hydrogen-1 connecting to oxygen.

Since heuterium is heavier than hyrogen-1, the deuterium oxide will have a slower molecular vibration correct?

Can you tell me other permutations of this?

Mainly, can I have a few samples involving deuterium that have different molecular vibrations? (Besides just Heavy water and normal water?)
