Lipid molecules contain either saturated or unsaturated fatty acids. You may have seen different types of fatty acids listed in nutrition labels on foods Based on what you have learned about fatty acids, bonding, and naming of chemical compounds, see if you can make an educated guess as to what the chemical structures of the following fatty acids are. A. Monounsaturated fatty acids: Think about what unsaturated fats contain, and what number is indicated by the prefix mono- B. Polyunsaturated fatty acids: Think about what the prefix poly- means in the terms polypeptide and polymer. C. Trans fats: Think about how the prefix trans- is used in naming alkenes.
