Q: The oxidation of one of these compounds with a Jones reagent yields carboxylic acid, and they are the product of the reaction of a ketone with a Grignard reagent. Esters are formed via a reaction of carboxylic acid and this compound in a process named for Fischer. Consisting of a hydroxyl group bonded to a carbon atom, they are given the formula R-OH.

Q: According to a 2001 Science magazine report this molecule, which is bound to the protein apolipoprotein E, is the synapse-promoting signal released by the glial cells. In their 1985 Nobel lecture, Brown and Goldstein discussed a receptor-mediated pathway for the homeostasis of this bio-molecule. This molecule also decreases the rigidity of cellular membranes, especially at low temperatures. It is the common precursor of steroid hormones, and also forms crystals in gout and in gallstones with bile salts and phospholipids. Importantly, apolipoprotein E, phospholipids, and free forms of this molecule have been  shown to bind low density lipoproteins, or LDL. FTP, name this lipid which is often associated with atherosclerosis.
