What are the biosynthetic principles of terpenes?
-Terpenes are biosynthesized through the condensation of isoprene units (C5 units), linked head to tail. This process results in various types of terpenes, such as monoterpenes, sesquiterpenes, diterpenes, triterpenes, and tetraterpenes.
How do saponins function in the body?
-Saponins have shown beneficial effects on blood cholesterol levels and cancer risk. They bind with bile acid and cholesterol in the intestinal tract, forming small micelles that facilitate absorption and excretion, thereby reducing blood cholesterol levels and potentially lowering cancer risk.
What are tocotrienols and tocopherols?
-Tocotrienols and tocopherols are members of the vitamin E family. Tocotrienols are unique for their unsaturated side chain with three double bonds, differing structurally from tocopherols which lack these double bonds. Both are essential nutrients with various health benefits.
What are the health benefits of tocotrienols?
-Tocotrienols have been shown to reverse carotid atherosclerosis, suppress cancer and tumor growth, act as powerful antioxidants, slow aging and protect skin when applied topically, and reduce platelet aggregation, potentially inhibiting blood clotting and hypertension development.
How do terpenes and terpenoids contribute to the medicinal properties of plants?
-Terpenes and terpenoids have demonstrated various medicinal properties, such as antidepressant, antifungal, antimicrobial, analgesic, anticonvulsant, and anti-inflammatory effects. They can be found in many plant foods and have been isolated from plants for their therapeutic uses.
What is the significance of the double bonds in tocotrienols?
-The double bonds in tocotrienols contribute to their potent antioxidant properties, which are stronger than those of tocopherols. This structural difference is responsible for their increased effectiveness in combating free radicals and their various health benefits.
How do terpenes and terpenoids affect the aroma of citrus fruits?
-When citrus fruits are squeezed, volatile terpene compounds are released, contributing to the distinct aroma of the fruit. Different parts of the fruit, like the peel versus the juice, can emit different terpene compounds, resulting in a varied aromatic profile.
What are some common sources of tocotrienols?
-Common sources of tocotrienols include palm oil, rice bran oil, barley, coconut oil, and annatto. These sources can be incorporated into the diet to obtain the health benefits associated with tocotrienols.
