A known mixture of compounds A and B gave the following HPLC results: Concentration (mg/mL in Peak area Compound mixture) (arbitrary units) A 1.03 10.86 B 1.16 4.37 A solution was prepared by mixing 12.49 mg of B plus 10.00 mL of unknown containing just A and diluting to 25.00 mL. Peak areas of 5.97 and 6.38 were observed for A and B, respectively. Find the concentration of A (mg/mL) in the unknown.
March 29, 2016 Chapter 10: Lipids, membranes, and cellular transport Major functions of lipids: signaling have limited solubility in aqueous media Triacylglycerides: Glycerol esterﬁed with three fatty acids Unsaturated fatty acids contain one or more cis C=C double bonds saturated fatty acids contain no C=C double bonds. The ﬂuidity of fatty acids decreases as the chain length increases and the number of cis double bonds decreases. Sphingolipids built on amino alcohol sphingosine built from serine and palmitate major component of membranes glycans attached to sphingosine Cholesterol disrupts regular fatty acid chain
