Amino Acid (Glucogenic/Ketogenic)
Ketogenic Amino Acids
Exclusively Ketogenic (Leucine/Lysine)
Lysine
1889 Discovery: Isolated by Ferdinand Heinrich Edmund Drechsel from the hydrolysis of casein, naming it "Lysin" (from Greek lysis, meaning loosening).
1902 Structural Elucidation: German chemists Emil Fischer and Fritz Weigert determined its structure and synthesized it.
1956 Industrial Milestone: The bacterium Corynebacterium glutamicum was isolated, allowing for large-scale lysine production via fermentation.
1958 Production Start: Kyowa Hakko Kogyo Co. Ltd. (now Kyowa Hakko Bio) pioneered the first industrial lysine fermentation process.
