A derivative of α-ketoglutarate and l-lysine that is an intermediate in l-lysine catabolism; elevated in cases of saccharopinuria.

MR spectra showed the presence of saccharopine, an intermediate in the Lys degradation pathway activated by the oligomycin treatment in line #163 (Supplementary Figure S3B), in agreement with previous data [17], and in lines #61 and #74.
A major metabolic difference between the two lines is that line #1, different to line #163, showed almost absent saccharopine formation after oligomycin treatment and belongs to one of the two GSC groups characterized by low/absent adipate content [17].

Although CDSs involved in intermediary metabolism were underrepresented among the deleted genes, 21 (42%) of deleted CDSs of this category were dehydrogenases (such as acyl-CoA short-chain alcohol, saccharopine, and aldehyde dehydrogenases), which are central enzymes in anaerobic metabolism (22) and important for survival in poorly oxygenated environments such as soil (23).
The major pathway for L-Lys metabolism in the liver occurs through the intermediate saccharopine (Hutzler and Dancis, 1968).
The major pathway of L-Lys metabolism in animals occurs through the intermediate saccharopine. This pathway predominates in the liver and is not very active in the brain (Hutzler and Dancis, 1968).
