The physical properties of a triacylglycerol are primarily determined by the chain length of the fatty acyl chains, the amount and {HEAD ~ type} of {TAIL ~ unsaturation} present in the fatty acyl chains, and the distribution of the different fatty acyl chains among the triacylglycerols that make up the fat or oil
