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
Fatty acids are the long chain hydrocarbons and a

- 1 Hyaluronic acid acts as a lubricant in the synovial fluid of joints. In rheumatoid arthritis, inflammation breaks hyaluronic acid down to smaller molecules. Under these conditions, what happens to the lubricating power of the synovial fluid?arrow_forward19. The omega-3 class of polyunsaturated fatty acids (PUFAS) has potent effects on cardiovascular function. The most active omega-3 PUFAS are docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). These PUFAS are precursors of which of the following biologically active lipids? a. gangliosides b. leukotrienes c. prostaglandins d. resolvins e. thromboxanesarrow_forwardIndicate whether each statement is true or false: (a) Trans fats are saturated. (b) Fatty acids are long-chain carboxylic acids. (c) Monounsaturated fatty acids have one CC single bond in the chain, while the rest are double or triple bonds.arrow_forward

- 1. Abundant trans bonds make partially hydrogenated vegetable oil a very unhealthy food choice. Vegetable oil can also be hydrogenated until it becomes fully saturated with hydrogen atoms. Would the physical properties of the hydrogenated and partially hydrogenated oils differ? If so, how and why would the differences occur? Do you think that full hydrogenation makes vegetable oil more or less healthy to eat, or does it have no effect? 2. Lipoprotein particles are relatively large, spherical clumps of protein and lipid molecules (see Figure 3.18) that circulate in the blood of mammals. They are like suitcases that move cholesterol, fatty acid remnants, triglycerides, and phospholipids from one place to another in the body. Given what you know about the insolubility of lipids in water, which of the four kinds of lipids would you predict to be on the outside of a lipoprotein clump, bathed in the water-based fluid portion of blood? 3. In 1976, a team of chemists in the United Kingdom was…arrow_forwardIn which solvents or solutions will a lipid be soluble: (a) CH 2Cl 2; (b) 5% aqueous NaCl solution; (c) CH 3CH 2CH 2CH 2CH 3?arrow_forwardThree examples of steroids are shown.
