Textbook QuestionDraw the skeletal structure and give the name and omega number of the following fatty acid: CH₃CH₂CH₂CH₂CH₂HC=CHCH₂HC= CHCH₂CH₂CH₂CH₂CH₂CH₂CH₂COOH
Textbook QuestionCertain omega-3 fatty acids can be found only in animal sources, such as fatty fish. Two of these are eicosapentaenoic acid (EPA) [20:5] and docosahexaenoic acid (DHA) [22:6], both of which are ω-3 fatty acids. DHA has been shown to be important in healthy brain development, so it has recently been added to infant formulas. Breast milk is rich in DHA as long as the mother maintains a healthy diet that includes fish. Draw skeletal structures of the fatty acids EPA and DHA.
