Question

Margarine is produced from vegetable oil by a process that does which of the following?

-removes hydrogen, which increases the number of double bonds in their phospholipid tails
-adds carbons, which increases the length of their phospholipid tails
-removes carbons, which decreases the length of their phospholipid tails
-freezes the phospholipids, which removes their double bonds
-adds hydrogen, which removes the double bonds from their phospholipid tail

Answer 1

Margarine is produced from vegetable oil through the process of hydrogenation, which converts the carbon-carbon double bonds in the fatty acids of the oil into single bonds. This process increases the melting point of the oil and transforms it into a solid or semisolid form, creating margarine.

Step-by-step explanation:

Margarine is produced from vegetable oil through the process of hydrogenation. During hydrogenation, hydrogen gas is bubbled through vegetable oil in the presence of a catalyst, such as nickel, platinum, or palladium. The hydrogen gas reacts with the carbon-carbon double bonds present in the fatty acids of the oil, converting them into single bonds. This process increases the melting point of the oil and converts it into a solid or semisolid form, creating margarine.
