this statement is true, please prvide counterargument
"A saturated fatty acid sample has a high boiling point. A triacylglycerol is composed of glycerol and three saturated fatty acids. Therefore, a sample not containing this triacylglycerol will have a low boiling point."
How many different triacylglycerols are there in which one of the fatty acid components is lauric acid, one is myristic acid, and one is palmitic acid?
Calculate the theoretical yield of 2mL of vegetable oil saponification reaction with 2mL of 6M NaOH and 40mL of saturated salt solution(NaCl).
GIVENS:
density of the oil = 0.9 g/mL
each fatty acid side chain of the oil has 18 C atoms (C_18: the carbonyl carbon, plus a C_17 carbon chain). Assume an average of one unsaturation per side chain.
