Methionine Metabolism and Activated Methyl Cycle | Pathway and Purpose

The video tutorial explains methionine metabolism, highlighting its role as an essential amino acid obtained from dietary sources. It details the methionine metabolism pathway, emphasizing the production of succinyl COA and its utilization in the TCA cycle for ATP generation. The tutorial covers the activated methyl cycle, the role of S-Adenosyl Methionine as a methyl donor, and the importance of vitamin B12-dependent enzymes. It also discusses the energy generation pathway from methionine, involving cystathionine and the TCA cycle.
