A fat or triacylglycerol would be formed as a result of a – A triglyceride (TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids (from tri-and glyceride). Triglycerides are the main constituents of body fat in humans and other vertebrates, as well as vegetable fat. They are also present in the blood to enable the bidirectional transference of adipose fat and blood glucose from the liver, and are a majord. is more closely related to humans than to rats e. may have evolved from rats but not from humans and gibbons Q3 A fat (or triacylglycerol) would be formed as a result of a dehydration reaction…A fat (or triacylglycerol) would be formed as a result of a dehydration reaction between _____. three molecules of 9 and one molecule of 10.
