Verified step by step guidance

Understand the concept of emulsification: Emulsification is the process of breaking down large fat globules into smaller, uniformly distributed particles. This increases the surface area for digestive enzymes to act upon, facilitating fat digestion.

Identify the role of bile salts: Bile salts are amphipathic molecules, meaning they have both hydrophilic (water-attracting) and hydrophobic (water-repelling) parts. This unique structure allows them to interact with both water and fats.

Recognize the function of bile salts in digestion: Bile salts are secreted by the liver and stored in the gallbladder. During digestion, they are released into the small intestine where they surround fat droplets, preventing them from coalescing and forming larger globules.

Differentiate between the options: Triglycerides are the main form of fat in the diet and are the target of emulsification, not the emulsifying agent. Cholesterol is a component of cell membranes and a precursor for steroid hormones, but it does not play a direct role in emulsification. Phospholipids are part of cell membranes and can act as emulsifiers, but in the context of digestion, bile salts are the primary emulsifying agents.

Conclude with the correct answer: Based on the understanding of emulsification and the role of bile salts, the substance important for the emulsification of fats during digestion is bile salts.
