DHA is a fatty acid derived from fish oil and an abundant fatty acid in vertebrate brains. Hydrogenation of DHA forms docosanoic acid [CH3(CH2)20CO2H], and ozonolysis forms CH3CH2CHO, CH2(CHO)2 (five equivalents), and HCOCH2CH2CO2H. What is the structure of DHA if all double bonds have the Z configuration?
