The video tutorial explores mannose metabolism, highlighting its entry into glycolysis before PFK, and its role as an epimer of glucose. Mannose is converted to mannose 6-phosphate, then to fructose 6-phosphate, entering glycolysis. While not a major energy source, mannose is crucial in biosynthesis, particularly in glycoproteins.

What is the significance of mannose in metabolism compared to glucose?

How does mannose differ from glucose in terms of stereochemistry?

Explain the role of mannose 6 phosphate in the metabolic pathway.

Describe the process by which mannose is converted to fructose 6 phosphate.

What are the primary sources of energy in metabolism, and how does mannose fit into this?
