Non-commutative substances in chemistry are elements or compounds that do not follow the commutative property. This means that the order in which they interact or combine can affect the outcome of a reaction. An example of a non-commutative substance is hydrogen peroxide (H2O2), which can react differently depending on the order of reagents added.
Enzymes are essential for human health because they catalyze biochemical reactions in the body, facilitating processes like digestion, metabolism, and energy production. Without enzymes, these processes would occur too slowly to sustain life. Enzymes also play a role in immune function and help repair damage to cells and tissues.
