GenAlex Medical, a little-known division of a major Swiss pharmaceutical firm, recently developed a new synthetic steroid S. Their patent application describes S as "made from a steroid nucleus with hydroxyl groups at positions 3 and 7, and methyl groups at positions 4 and 12." In the drawing space below, draw the chemical structure of S. If more than one structure is possible, you can draw any of them. Click and drag to start drawing a structure. X 0:0

A certain phospholipid molecule contains two fatty acid chains of eight carbon atoms each having no carbon-carbon double bonds in the chain. The phosphate ion is attached to a polar organic molecule, X, just as highlighted in yellow in the figure in the introduction. Complete the structure of the phospholipid molecule using the structure in the introduction. To include a X group in your structure, draw another atom, hover over the atom with the mouse, and then press the X key on your keyboard.

You're an undercover biological weapons agent who has been given an unknown liquid - you suspect that it is just sugar water (because you drank some by accident - you know you're not supposed to have food or drink in the lab, but you do it all the time, and it tasted sweet - plus you didn't die!) One of the tests you need to run is to see if it contains protein (remember, foreign proteins can cause severe immune responses which can be a powerful biological weapon). You set up 3 test tubes each with 10mL of the following: distilled water, gelatin solution and the unknown. The distilled water is clear, the gelatin solution is clear with a beige tint, and the unknown is clear. You use Biuret's Reagent - a dark blue dye which will turn a liquid sample purple in the presence of protein. 1. When Biuret's Reagen is added to the unknown, predict what color you expect it to become if the unknown is just sugar water: [a] (no change | blue | purple). 2.You included both a positive and negative…

The monomers of lipids are called fatty acids. Draw the lipid monomer a fatty acid, labeling the hydrocarbon chain and the carboxyl end group. Be sure to show ALL of the atoms within the molecule (there are several different fatty acids in living things including oleic acid and stearic acid, each with a unique molecular formula). Do not give handwriting solution.
