Cafestol
Cafestol[edit | edit source]
Cafestol is a diterpene molecule found in coffee beans. It is one of the compounds responsible for the characteristic flavor and aroma of coffee. Cafestol is also known for its potential effects on human health, particularly its impact on cholesterol levels.
Chemical Structure[edit | edit source]
Cafestol is a diterpene, which is a type of hydrocarbon composed of four isoprene units. Its chemical formula is C\textsubscript{20}H\textsubscript{28}O\textsubscript{3}. The structure of cafestol includes a cyclopentane ring fused to a cyclohexene ring, with several methyl groups and a hydroxyl group attached.
Sources[edit | edit source]
Cafestol is primarily found in unfiltered coffee beverages, such as Turkish coffee and French press coffee. The compound is present in the oily fraction of coffee and is extracted during the brewing process. Filtered coffee, such as that made with a drip coffee maker, contains significantly lower amounts of cafestol because the paper filter traps the oily compounds.
Health Effects[edit | edit source]
Cafestol has been studied for its effects on cholesterol levels in humans. It is known to increase serum cholesterol by inhibiting bile acid synthesis, which leads to an increase in cholesterol levels in the blood. This effect is more pronounced in individuals who consume large amounts of unfiltered coffee.
Cholesterol[edit | edit source]
Cafestol raises both low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol levels. The increase in LDL cholesterol is of particular concern because it is associated with an increased risk of cardiovascular disease.
Metabolism[edit | edit source]
Cafestol is metabolized in the liver. It undergoes various transformations, including hydroxylation and conjugation, before being excreted from the body. The metabolism of cafestol can vary between individuals, which may influence its effects on cholesterol levels.
Research[edit | edit source]
Ongoing research is exploring the potential health benefits and risks associated with cafestol consumption. Some studies suggest that cafestol may have anti-inflammatory and anti-cancer properties, although more research is needed to confirm these effects.
