What is the structure of an optically inactive triacylglycerol that yields two moles of oleic acid and one mole of palmitic acid when hydrolyzed in aqueous acid?
A simple triacylglycerol is one that:
a) Upon hydrolysis produces glycerol and three different fatty acids.
b) Upon hydrolysis produces glycerol and at least two different fatty acids.
c) Upon saponification gives glycerol and three fatty acid salts.
d) Upon saponification gives three esters.
e) Upon hydrolysis produces glycerol and three mol of a fatty acid.
What types of bond(ether, amide, ester .... etc) covalently attach the fatty acyl chains and the phosphocholine moeity to the glycerol backbone of the dipalmitoyl phosphatidylcholine?
