Question

All of the following are accurate about saturated fats except: 1. Solid at room temperature 2. Have single bonds within carbon chain 3. Usually obtained from animal sources 4. Usually dissolve easily in water

Answer 1

Last option

First option is correct because the molecules of saturated fats can pack tightly with each other. This is because they have single bond in them. They are straight chain molecules. Because of this, they can be compactly arranged and are therefore solid at room temperature. They also have a higher melting point.

Second statement is correct because all bonds present in saturated fats are single bond. Double and triple bonds are present in unsaturated fats.

Third statement is correct because milk of cow and other animals are used to produce margarine which are rich in saturated fatty acids.

Fourth statement is incorrect because they are hydrophobic molecules and insoluble in water.
