Discuss the function and structure of triglycerides in a living organism. Triglycerides are known to have a complex structure and function. Their structure contains carbons, hydrogen's, a carboxyl group and a hydroxyl group. The triglycerides, which act mainly as energy stores in animal and plants, are a large important group of lipids. A triglyceride consists of one molecule of glycerol and three fatty acids. The following shows how the triglyceride is formed and it also shows the structure of a triglyceride: Looking at the diagram above only one glycerol is attached to (by dehydration synthesis) 3 fatty acids. The fatty acids determine the characteristics or properties of the fat. The bond formed between the -OHs of the glycerol and the -OHs of the fatty acid is an ester bond. Fatty acids are chains of hydrocarbons 4 - 22 carbons long with the carboxyl functional (acid) group at end. Each carbon within the...
