Gamma-tocopherol

Gamma-tocopherol

Gamma-tocopherol is one of the eight members of the group of related molecules collectively known as vitamin E. This nutrient plays a crucial role in antioxidant activities.

Structure and Properties

Gamma-tocopherol is a type of tocopherol, which is a class of chemical compounds consisting of various methylated phenols. The molecule is composed of a chromanol ring, with a hydroxyl group that can donate a hydrogen atom to reduce free radicals, and a hydrophobic side chain which allows for penetration into biological membranes.

Biological Significance

Gamma-tocopherol is found naturally in various foods such as soybean oil, corn oil, and certain types of nuts. It is the most common form of vitamin E in the North American diet, but is not as bioavailable or as actively retained in the human body as the alpha-tocopherol form.

Despite this, gamma-tocopherol has been recognized for its unique benefits to human health. It has been found to have anti-inflammatory properties, and may play a role in the prevention of cancer and cardiovascular disease.

Dietary Sources and Supplements

Gamma-tocopherol is found in high amounts in dietary fats, particularly vegetable oils like soybean, corn, and canola oil. Nuts and seeds, such as walnuts, pecans, and sesame seeds, are also good sources of this nutrient.

In addition to dietary sources, gamma-tocopherol can also be obtained through supplements. However, most vitamin E supplements contain only alpha-tocopherol, and not gamma-tocopherol.
