Verified step by step guidance

Step 1: Understand the structure of a triglyceride. A triglyceride is composed of a glycerol backbone and three fatty acid chains. Glycerol contains hydroxyl (-OH) groups, and fatty acids contain carboxyl (-COOH) groups.

Step 2: Identify the type of reaction involved in forming a triglyceride. The reaction is a dehydration synthesis (condensation reaction), where water is removed as the functional groups bond together.

Step 3: Determine which functional groups participate in the reaction. Hydroxyl groups (-OH) from glycerol react with carboxyl groups (-COOH) from fatty acids to form ester bonds.

Step 4: Recognize the byproduct of the reaction. Each ester bond formation releases one molecule of water (H₂O) as a result of the dehydration synthesis.

Step 5: Conclude that the correct functional groups involved in the reaction are hydroxyl groups and carboxyl groups, as they are responsible for forming the ester bonds in triglycerides.
