Glycosides for temporary detoxification<br />

Aglycoside is a molecule in which (1) a sugar is<br />

bound to (2) a non-carbohydrate moiety: some<br />

other organic molecule. The sugar group is then<br />

known as (1) the glycone and the non-sugar<br />

group as (2) the aglycone or genin part <strong>of</strong> the<br />

glycoside.<br />

<strong>Plants</strong> store chemicals including toxins in the<br />

form <strong>of</strong> inactive glycosides. These can be<br />

activated by hydrolysis, which causes the sugar<br />

part to break <strong>of</strong>f, making the chemical ready to<br />

act. Also in animals and humans, poisons are<br />

<strong>of</strong>ten bound to sugar molecules as part <strong>of</strong> their<br />

detoxification.
