Classification

Biological Context

C24 dihydro Ceramide is a sphingolipid that has been found in the stratum corneum of human skin.¹ It is found in higher concentrations in female sebum compared to male sebum.² C24 dihydro Ceramide levels positively correlate with cytotoxicity in CCRF-CEM, MOLT-4, COG-LL-317h, and COG-LL-332h T cell acute lymphoblastic leukemia (ALL) cell lines.³ Levels of C24 dihydro ceramide are increased by 149.49-fold in dihydroceramide desaturase 1 (DEGS1) knockdown UM-SCC-22A human head and neck squamous carcinoma cells in vitro. 4 C24 dihydro Ceramide levels are also increased in INS-1 β-cells incubated with glucose and palmitate .⁵
