Draw the structure.Saccharide X occurs in the roots of several species of plants. Deduce the structure of saccharide x from the following data:1. Acidic hydrolysis of 1 mol of stachyose yields 2 mol of D-galactose, 1 mol of D-glucose, and 1 mol of D-fructose.2. Stachyose is a nonreducing sugar.3. Treating stachyose with an a-galactosidase produces a mixture containing D-galactose, sucrose, and a nonreducing trisaccharide calledraffinose.4. Acidic hydrolysis of raffinose gives D-glucose, D-fructose, and D-galactose. Treating raffinose with an a-galactosidase yields D-galactoseand sucrose. Treating raffinose with invertase (an enzyme that hydrolyzes sucrose) yields fructose and melibiose5. Methylation of saccharide x followed by hydrolysis yields 2,3,4,6-tetra-O-methyl-D-galactose, 2,3,4-tri-0-methyl-D-galactose,2,3,4-tri-O-methyl-D-glucose, and 1,3,4,6-tetra-O-methyl-D-fructose.

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.
