The property of saturated fatty acids that is not correct from the options provided is "made by animals."
1. Single carbon-to-carbon bonds: Saturated fatty acids have single carbon-to-carbon bonds. This is a characteristic feature of saturated fatty acids, as they lack double bonds between carbon atoms in their hydrocarbon chain.
2. Solid at room temperature: Saturated fatty acids are usually solid at room temperature. This is due to the tightly packed structure resulting from the absence of double bonds, which allows them to stack closely together, leading to a solid state.
3. Made by animals: While saturated fatty acids can be found in animal products, they are not exclusively produced by animals. Saturated fatty acids are also present in various plant sources like coconut oil and palm oil.
Therefore, the property that is not accurate in the context of saturated fatty acids among the options provided is "made by animals."
