When it comes to dietary fats, the position of the double bond on the fatty acid chain can have an impact on its properties and effects on the body.
The “sn-2” position refers to a specific location on the glycerol molecule where the fatty acid is attached.
In the case of DHA, when it is esterified at the sn-2 position, it means that it is attached at the second carbon atom on the glycerol molecule.
Studies have shown that DHA in the sn-2 position may have better absorption and bioavailability than DHA in other positions.
