Answer:
Based on the information, the compound is a phospholipid.
Explanation:
Phospholipids are made up of a fatty acid tail which is hydrophobic in nature and a head which comprises of phosphates that is hydrophilic in nature. Hence, phospholipids are amphiphilic compounds so they will be partially soluble in water and will allow water-soluble substances to mix with fats.
Hence, the composition of the substance described in the question confirms that is a phospholipid. As it's structure contains hydrocarbon and phosphorus and might also contain nitrogen.
