Docosahexaenoic acid, DHA, 22:6 (n-3), is an omega-3 fatty acid. DHA is either obtained from the diet or converted in small amounts from eicosapentaenoic acid, EPA. Via docosapentaenoic acid, DPA, as an intermediate.
DHA can be biosynthesized from alpha-linolenic acid, but this does not appear to be very efficient, and it's hard to get enough DHA needed through ALA.

DHA In The Brain And Eyes
Docosahexaenoic acid, DHA, is a polyunsaturated very long-chain omega 3 fatty acid. It is metabolically related to other n-3 fatty acids. (source 🗗)
DHA is found in high concentrations in the human brain and eye, where it is linked to better development and function. (source 🗗)

DHA Convertion From ALA
DHA can be biosynthesized from alpha-linolenic acid. But it does not appear to be very efficient in many individuals. But the conversion of ALA to DHA is much better in young women than in young men. Infants may be more efficient converters of ALA to DHA than many adults. (source 🗗)
DHA Is So Important For Infants
DHA is abundant in human breast milk. Rarely is DHA added to infant formulas, which is a large problem. (source 🗗)
Many infants have been fed formula diets lacking DHA and other important omega-3 fatty acids. DHA deficiencies are associated with problems like attention deficit hyperactivity disorder (ADHD). But also cystic fibrosis, phenylketonuria, depression, and aggressive hostility. (source 🗗)
DHA In Food
DHA is found in large quantities in fatty fish, like salmon, tuna, mackerel. At lower levels, you find DHA in meat and eggs.
Fatty, oily fish is one of the best sources of DHA.
