Which is the anomeric carbon? I chose the one on the top left (substituent to carbon 5), but I believe it should be carbon actually in the cyclohexane, so my next guess would be bottom left (carbon 4). I'm a little confused.

A bacterial culture is grown using either octadecane (C18H38) or pentachlorophenol (C6HOCl5)) as the sole source of carbon and energy. The cell yield value is determined by dry weight analysis to be 1.49 for octadecane and 0.05 for pentachlorophenol. Using either octadecane or pentachlorophenol, please describe the steps taken (and the final result) showing what percentage of the substrate carbon will be found as cell mass and as CO2? Please show all calculations and give correct answers.

Soy sauce is made by fermenting a salty combination of soybeans and wheat for 8 to 12 months with a variety of microorganisms, including yeast. After the particles are removed, the resultant sauce is high in lactate and ethanol. What is the process for making these two compounds? To avoid a pronounced vinegary flavor in the soy sauce, air must be kept out of the fermenting tank (vinegar is dilute acetic acid). Why?

An octapeptide was hydrolyzed and the amino acids separated. Its amino acid composition was determined: Gly (1); Ala (2); Val (1); Lys (2); Met (1); Asp (1). After incubation with FDNB and hydrolysis, 2,4-dinitrophenylalanine was detected. NO2 H H N C COOH ON- CH, Treatment with cyanogen bromide, which cleaves at M, resulted in two fragments: a pentapeptide containing two K residues and a tripeptide containing V, G, and A. The residues are not listed in any particular order. After treatment with trypsin, which cleaves at R and K, there were three fragments: two dipeptides and MGAV. What is the sequence of the octapeptide? Use the one-letter abbreviations for the amino acids, and do not use dashes.
