3-keto Sphinganine (d8:0) is a short-chain analog of the typical C18 chain-length 3-keto sphinganine (d18:0) . 3-keto Sphinganine (d18:0) is a lyso-sphingolipid formed by the condensation of L-serine and palmitoyl-CoA by serine palmitoyl transferase (SPT). Vitamin K deficiency inactivates SPT resulting in a decrease in the production of 3-keto sphinganine and other sphingolipids.
