Gamma-Carotene

Gamma-Carotene is a type of carotenoid, a class of pigments that are naturally occurring in the chloroplasts and chromoplasts of plants and some other photosynthetic organisms like algae, some types of fungus and some bacteria. Gamma-Carotene is a precursor of vitamin A and is converted to it in the body. It is an isomer of beta-carotene.

Structure and Properties

Gamma-Carotene has a molecular formula of C40H56 and a molecular weight of 536.87 g/mol. It is a hydrocarbon with a cyclic structure and contains 11 conjugated double bonds. This structure is responsible for its characteristic orange color. It is less stable than beta-carotene due to the presence of a central double bond.

Sources

Gamma-Carotene is found in many fruits and vegetables, especially those that are orange or red in color. Some of the richest sources include carrots, pumpkins, and sweet potatoes. It can also be found in certain types of algae and bacteria.

Health Benefits and Risks

Like other carotenoids, gamma-carotene has antioxidant properties. It can help protect the body from damage by free radicals and may reduce the risk of chronic diseases like heart disease and cancer. However, more research is needed to fully understand these potential benefits.

There is some evidence that high intake of carotenoids like gamma-carotene can increase the risk of lung cancer in smokers. However, this risk does not seem to apply to non-smokers or to people who get their carotenoids from food rather than supplements.
