Draw the structure of a lecithin containing oleic acid and palmitic acid as the fatty acid side chains.

Lecithin comes under the category of phospholipids. It comprises of glycerol, two fatty acids, choline, and a phosphate group. They also possess lubricant and emulsification properties, and are employed as surfactants.

Fatty acids form a category of lipids. They constitute carboxylic acids comprising long aliphatic tails. These are categorized into unsaturated and saturated fatty acids.

Lecithin is a type of phosphoacylglycerol. Two of the hydroxyl groups of glycerol are esterified with fatty acids. The third OH group is a portion of the phosphodiester connected to other low molecular weight alcohol.

The structures can be given as:
