Common Name3-Dehydrosphinganine
Description3-Dehydrosphinganine, also known as KDHS or ketodihydrosphingosine, belongs to the class of organic compounds known as beta-hydroxy ketones. These are ketones containing a hydroxyl group attached to the beta-carbon atom, relative to the C=O group. Thus, 3-dehydrosphinganine is considered to be a sphingoid base lipid molecule. 3-Dehydrosphinganine is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 3-Dehydrosphinganine exists in all eukaryotes, ranging from yeast to humans. Within humans, 3-dehydrosphinganine participates in a number of enzymatic reactions. In particular, 3-dehydrosphinganine and carbon dioxide can be biosynthesized from palmityl-CoA and L-serine through the action of the enzyme serine palmitoyltransferase 1. In addition, 3-dehydrosphinganine can be biosynthesized from sphinganine; which is catalyzed by the enzyme 3-ketodihydrosphingosine reductase. In humans, 3-dehydrosphinganine is involved in the metabolic disorder called the krabbe disease pathway. Outside of the human body, 3-Dehydrosphinganine has been detected, but not quantified in, several different foods, such as common chokecherries, black huckleberries, pomegranates, cinnamons, and flaxseeds. This could make 3-dehydrosphinganine a potential biomarker for the consumption of these foods. A 2-amino-1-hydroxyoctadecan-3-one that has S-configuration. 3-Dehydrosphinganine is expected to be in Cannabis as all living plants are known to produce and metabolize it.

Specific function:
Serine palmitoyltransferase (SPT). The heterodimer formed with SPTLC2 or SPTLC3 constitutes the catalytic core. The composition of the serine palmitoyltransferase (SPT) complex determines the substrate preference. The SPTLC1-SPTLC2-SPTSSA complex shows a strong preference for C16-CoA substrate, while the SPTLC1-SPTLC3-SPTSSA isozyme uses both C14-CoA and C16-CoA as substrates, with a slight preference for C14-CoA. The SPTLC1-SPTLC2-SPTSSB complex shows a strong preference for C18-CoA substrate, while the SPTLC1-SPTLC3-SPTSSB isozyme displays an ability to use a broader range of acyl-CoAs, without apparent preference.
