Sphingosines are long-chain base precursors of cellular sphingolipids used directly in the synthesis of ceramide, which in combination with sialic acid forms ganglioside. Sphingosine can exist in four stereoisomers, however only sphingosine occurs naturally. Compared to other sphingolipids throughout the body, which are predominantly composed of C-18 sphingosine, only central nervous system (CNS) gangliosides contain significant amounts of sphingosine. The concentration of sphingosine within mammalian brain gangliosides apparently increases with developmental maturation. Furthermore, the ratio of C-18 to C-20 sphingosine in the brain is thought to be related to some nervous system degeneration processes.

CD2019 is a retinoic acid receptor beta (rarbeta) agonist, overcoming inhibition of axonal outgrowth via phosphoinositide 3-kinase signalling in the injured adult spinal cord.

Sphinganine (d20:0) is a natural isomer of dihydro-D-erythro-sphinganine (sphinganine (d18:0); that is a precursor of ceramide and sphingosine as well as a substrate for sphingosine kinases, which generate sphingosine-1-phosphate (d18:1) . In S. cerevisiae, the amount of sphinganine (d20:0) increases 10.8-fold in response to heat stress, indicating it is involved in heat stress adaptation. Sphinganine levels increase significantly in response to certain mycotoxins, including fumonisins as well as in some cancers. Sphinganine can block protein kinase C activation in some cases but not others.

Ganglioside GM1是一种单唾液酸化神经节苷脂，是含有一个唾液酸的原型神经节苷脂。C18 Ganglioside GM1主要存在于大脑的梨状皮质、杏仁核、纹状体和海马CA1区。在阿尔茨海默症患者的死后组织中，C18 ganglioside GM1 (d20:1/18:0)与C18 ganglioside GM1 (d18:1/18:0)的比例在海马齿状回外分子层中减少。由于该产品源自天然，因此鞘氨醇骨架可能会有所变化。[Matreya, LLC.]
