4-Hydroxysphinganine
Phytosphingosine is a phospholipid. Phospholipids are a class of lipids and a major component of all biological membranes; sphingolipid metabolites, such as sphingosine and ceramide, are highly bioactive compounds and are involved in diverse cell processes, including cell-cell interaction, cell proliferation, differentiation, and apoptosis. Phytosphingosine is also one of the most widely distributed natural sphingoid bases, which is abundant in fungi and plants, and also found in animals including humans. Phytosphingosine is structurally similar to sphingosine; phytosphingosine possesses a hydroxyl group at C-4 of the sphingoid long-chain base. The physiological roles of phytosphingosine are largely unknown. Phytosphingosine induces apoptosis in human T-cell lymphoma and non-small cell lung cancer cells, and induces caspase-independent cytochrome c release from mitochondria. In the presence of caspase inhibitors, phytosphingosine-induced apoptosis is almost completely suppressed, suggesting that phytosphingosine-induced apoptosis is largely dependent on caspase activities.

Phytosphingosine induces cell apoptosis via caspase 8 activation and Bax translocation in cancer cells[1].
4-hydroxysphinganine
4-hydroxysphinganine is a member of the class of compounds known as 1,3-aminoalcohols. 1,3-aminoalcohols are organic compounds containing an alkyl chain with an amine group bound to the C1 atom and an alcohol group bound to the C3 atom. 4-hydroxysphinganine is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). 4-hydroxysphinganine can be found in a number of food items such as fenugreek, citrus, chestnut, and boysenberry, which makes 4-hydroxysphinganine a potential biomarker for the consumption of these food products.
