Bile Acid Synthesis | Classic and Alternative Pathways | Primary and Secondary Bile Acids

The video tutorial explains bile acid synthesis from cholesterol in the liver, detailing the classic and alternative pathways. It covers the structural modifications of cholesterol, the role of enzymes like CYP 7A and CYP 27A1, and the formation of primary bile acids. The tutorial also discusses the conjugation of bile acids to amino acids, forming bile salts, and their function in digestion. Finally, it describes the conversion of primary bile acids to secondary bile acids by bacterial enzymes.

What are the two main pathways for bile acid synthesis discussed in the lesson?

Explain the role of bile acids in the digestion and absorption of fats.

What modifications occur to cholesterol to form primary bile acids?

Describe the function of the enzyme cholesterol 7A hydroxylase in bile acid synthesis.

What is the significance of vitamin C in the function of cholesterol 7A hydroxylase?

What are the two primary bile acids mentioned in the lesson?

How do primary bile acids undergo negative feedback regulation in bile acid synthesis?

Explain the process of conjugating amino acids to bile acids and its purpose.

What role do bacterial enzymes play in the conversion of primary bile acids to secondary bile acids?

What are the differences between primary bile acids and secondary bile acids?
