Verified step by step guidance

Understand the function of bile: Bile is a digestive fluid produced by the liver and stored in the gallbladder. It aids in the digestion and absorption of fats in the small intestine.

Identify the components of bile: Bile primarily consists of bile salts, bilirubin, cholesterol, and water. These components work together to emulsify fats and facilitate their absorption.

Recognize the role of bile salts: Bile salts are crucial for breaking down and absorbing dietary fats. They are derived from cholesterol and are a major component of bile.

Understand the presence of bilirubin: Bilirubin is a byproduct of the breakdown of red blood cells and is excreted in bile. It gives bile its characteristic yellow-green color.

Identify the outlier: Amylase is an enzyme that breaks down carbohydrates and is not a component of bile. It is primarily found in saliva and pancreatic juice, not in bile.
