In citrus, including grapefruit, present a form limonida as limonin glucoside - i.e., the compound of limonoids with a glucose molecule. When this substance enters the digestive tract, the body "picks" glucose, which it will use as a fuel and releases limonene.
During the experiment, sixteen volunteers were given different doses of limonin glucoside. Blood tests showed that the concentration limonin in blood plasma of the subjects reached a maximum six hours after his admission, and at five limonin traces of blood were found 24 hours later. Limonin bioavailability and to remain in the body for a relatively long time is now considered one of the reasons why grapefruit, together with other citrus fruit can limit the growth of cancer cells.
