Mammals have six ceramide synthases that exhibit relatively strict specificity regarding the chain-length of their acyl-CoA substrates. Ceramide synthase 1 (CERS1) is structurally and functionally distinctive from all other CERS enzymes, and is specific for stearoyl-CoA as the acyl donor. It can use multiple sphingoid bases including sphinganine, sphingosine, and phytosphingosine.
