What is the density and molar mass for stearic acid?
1. The stearic acid/hexane solution contains 0.1 g of stearic acid per 1 mL of solution. What is the molarity of this solution?
Triacylglycerol A contains 53% oleic acid, 29% linoleic acid, 9% palmitic acid, 4% stearic acid, 1% myristic acid and lesser amounts of other fatty acids. Triacylglycerol B contains 39% oleic acid, 29% palmitic acid, 24% stearic acid, 2% myristic acid, 2% linoleic acid, and lesser amounts of other fatty acids. Which of the two samples is expected to be solid at room temperature? Why pls? Thanks
List at least 3 uses of stearic acid and comment on why this chemical substance is so useful in different applications.
Determine the total ATP yield from beta-oxidation of complete oxidation of stearic acid. Show your work
Stearic acid (C18H36O2) is a fatty acid, a molecule with a long hydrocarbon chain and an organic acid group (COOH) at the end. It is used to make cosmetics, ointments, soaps, and candles and is found in animal tissue as part of many saturated fats. In fact, when you eat meat, you are ingesting some fats containing stearic acid. ( of C18H36O2 = –948 kJ/mol, CO2=-393.5kJ/mol, H2O=-241.826kJ/mol). Calculate the heat (q) released in kcal when 3.765 g of stearic acid...
What reaction occurs when sodium hydroxide is added to the stearic acid in cyclohexane and water? How does this change the solubility of cyclohexane in water? Does HCl reverse this reaction when it is added? If so why? Does sodium chloride have the same type of behavior as stearic acid or is it different? Explain why these two solutes are the same or different. (Please answer in your own words.)
Stearic acid (CH3(CH2)16COOH) is a common long-chain acid found in waste streams. Many microorganisms are capable of using stearic acid and derived metabolites as substrates. Determine the maximum ATP yield (mmol ATP/g stearic acid) that can be achieved from the complete oxidation of stearic acid to water and CO2 during aerobic microbial respiration in typical cellular environments. For your calculation, you may assume that after electron transport driven ATP synthesis, 3 ATP molecules are produced per NAD(P)H and 2 ATP...
1.0345 g of palmitic acid dissolved in 8.7545 g of stearic acid. Calculate the freezing point of the solution. The molar mass of palmitic acid is 256.48 g/ mol. The molal freezing point constant , Kf for stearic acid is 4.5 degrees C/ m and pure stearic acid freezes at 69.3 degrees Celsius.
