We know that some reactions involving loss of water are reversible upon the addition of water (Le Chatelier's Principle). If we heat oleandrin in a solution of acidic water, what would remain attached to the steroid skeleton? Select the correct answer. E он он A Oleandrin is a toxic cardiac glycoside found in the poisonous plant, oleander (Nerium oleander L). It has a very long IUPAC name: acetic acid [(35,5R, 10S,13R,14S,16S, 17'R)-14-hydroxy-3-[[(2R,4S,5S,6S)-5-hydroxy-4-methoxy-6-methyl- 2-tetrahydropyranyl]oxy]-10,13-dimethyl-17-(5-oxo-2H-furan-3-y)-1,2,3,4,5,6,7,8,9,11,12,15,16,17- tetradecahydrocyclopenta[a]phenanthren-16-yl) ester F D E D E OH B он B он (a) no reaction он A (b) он он OH он OH он E он он (c) C он но (d)

I was at the supermarket the other day shopping for groceries, and I picked up a box of Schtuck Margarine. On the front of the box, it listed “5% trans fats” and on the ingredient list it had “hydrogenated corn oil” listed as the main ingredient. If corn oil is a polyunsaturated vegetable oil with cis- double bonds (only), why is it hydrogenated, and where are the trans fats coming from? Additionally, what is the issue with trans- fats?

The figure below illustrates the molecular structures of two fatty acids. A B H₂C The structural formula of erucic acid and behenic acid с H₂C D erucic acid behenic acid Which of the following best explains why erucic acid is liquid at room temperature but behenic acid is solid at room temperature? O OH The presence of a double carbon to carbon bond in erucic acid prevents the molecule from packing closely together. The lack of any double carbon-carbon bonds in behenic acid causes the molecule to be come polar and therefore packed more tightly. The larger number of carbon atoms in erucic acid prevents the molecule from packing tightly together. OH The smaller number of carbon atoms in behenic acid creates stronger covalent bonds between the carbon atoms allowing for them to pack more tightly together.
