To draw: The skeletal structures of the fatty acids EPA and DHA. Introduction: Skeletal structure shows the bonds between the carbon atoms in the form of lines in two dimensions. The bonds between two carbon atoms are indicated by lines. The number of C − H bonds to any carbon atoms is equal to four minus the bonds formed by the carbon. Fatty acids are the long chain hydrocarbons and a carboxylic acid group is attached at the end of the chain. EPA is a Eicosapentaenoic acid that is found in fish oils. It consists of 20 carbons and has five double bonds. So, it is a polyunsaturated fatty acid as there are multiple double bonds present in it. DHA is a Docosahexaenoic acid that is also found in fish oils. It consists of 22 carbons and has six double bonds. So, it is a polyunsaturated fatty acid as there are multiple double bonds present in it.

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.

Certain 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.

You are given 150 mL of an oil made up of a mixture of 3 fatty acids: palmitoleic acid (C 16:1 (n-7)) erucic acid (C 22:1 (n-9)) stearidonic acid (C 18:4 (n-3)) You know that the 150 mL sample of this oil was prepared by adding 60 mL of palmitoleic acid to 90 mL of a mixture of erucic acid and stearidonic acid. Using a hydrometer you carefully measure the density of the 150 mL sample of oil and your analysis indicates that it has a density of 0.900 g/cm3. The densities of the individual fatty acids are: palmitoleic acid = 0.894 g/cm3 erucic acid = 0.860 g/cm3 stearidonic acid = 0.9334 g/cm3 Can you determine the volumes (in mL) of erucic acid and stearidonic acid in the total volume (150 mL) of the oil mixture?
