docosahexaenozoic

Docosahexaenoic acid, commonly known as DHA, is an omega-3 fatty acid. It is a polyunsaturated fatty acid with a chain of 22 carbons and six double bonds. DHA is a critical structural component of the brain and retina in humans. It plays a vital role in brain development during infancy and in maintaining cognitive function throughout life. The omega-3 designation refers to the position of the first double bond, which is three carbons away from the methyl end of the fatty acid chain.

Sources of DHA include fatty fish such as salmon, mackerel, and sardines, as well as certain algae. The human body can synthesize DHA from alpha-linolenic acid (ALA), another omega-3 fatty acid, but this conversion is often inefficient. Therefore, dietary intake of DHA is considered important for optimal health. DHA is often found in supplements and is added to some infant formulas. Its presence is linked to numerous physiological processes, including vision, neurological development, and inflammation regulation. Research continues to explore the full spectrum of DHA's health benefits.
