Cyclic forms of D-glucose: Haworth formulaThe furanose and pyranose forms of D-glucose can be presented using Haworth formula. The followingtemplates are used for this formula. Note the numbering of the carbon atoms and the anomeric carbon(this carbon defines the alpha and beta isomer).Furanose template (furan)Pyranose template (pyran)anomeric carbonanomeric carbonCompare the Fisher and Haworth formula of D-glucofuranose and D-glucopyranose. Notice that thegroups attached to C-1, C-2, and C-3 on the left side of the Fisher formula are written above the planeof the furanose template.Fisher formulaHaworth formulaH FOHH-2HOH,č 5-OHFOH-HHO-3H4онH1H-4H-5HOH36 CH2OHHOHAlpha-D-glucofuranoseAlpha-D-glucofuranoseHOH2C-онOHноHFOH-OHНоHH.OHHČH2OHBeta-D-glucofuranoseBeta-D-glucofuranose

What biochemical function do these Omega-3 fats play? Much cheaper alternative sources of omega-3 fats include fats from some seeds and nuts (most often from flax seed in consumer products), but the allure of fish oil sources maintains these products' popularity despite much higher prices. Is there a difference in the omega-3 fats derived from plant and animal sources? If so, explain the difference and why one is "better" than the other.
