What Is trans-Lycopene?

trans-Lycopene is the trans-isomer of the very beneficial nutrient Lycopene.

Lycopene is a very powerful antioxidant.

Plants and photosynthetic bacteria naturally produce all-trans lycopene.

trans-Lycopene belongs to the non-provitamin A family.

trans-Lycopene belongs to the family of isoprenoids and is a naturally occurring, non-toxic carotenoid.

It has been shown to be effective in cancer treatments and is currently being evaluated in a number of clinical trials.

trans-Lycopene Is The trans-Isomer Of Lycopene

Isomers are compounds with identical chemical formulas but different structures.

The cis-isomer indicates that the functional groups are on the same side of the carbon chain, while the trans-isomer indicates that functional groups are on opposing sides of the carbon chain. (source ◳)

When exposed to light or heat, trans-lycopene can undergo isomerization to any of several cis-isomers, giving it the same benefits Lycopene can provide.

Lycopene Is Red Pigment

Lycopene is a naturally occurring red carotenoid pigment that is responsible for the colors seen in tomatoes, pink grapefruit, and other foods.

It’s the all-trans configuration of lycopene that is the most predominant isomer found in foods that gives it the red color. (source ◳)

In a red tomato, 94–96% of total lycopene comes from all-trans-lycopene.

When trans-lycopene is ingested, it is poorly absorbed. (source ◳)

Lycopene Is Stable

Lycopene is more stable in the body than, for instance, beta-carotene. Beta-carotene can degrade and change its structure.

Lycopene is more stable, so it can be more effective.

trans-Lycopene In Tomatoes

trans-Lycopene is one of the predominant carotenoids in tomatoes. It is a powerful antioxidant that has anti-inflammatory and anticancer properties.

Heat processing of tomatoes converts the all-trans lycopene to various cis-isomers.

cis-lycopene isomers are regarded as more bioavailable because they are more soluble and better absorbed than the all-trans isomers.(source ◳)

Multiple studies have demonstrated that lycopene from processed tomato products is more bioavailable than lycopene from fresh tomatoes. (source ◳)
