Question
This compound holds DSPC, DMA, and PEGylated (“peg-uh-lated”) DMG together in the nanoparticles designed by Moderna for drug delivery. The chiral nematic phase is named for this compound because liquid crystals were discovered in its benzoate ester. This molecule’s polar -OH (“O-H”) group orients with sphingomyelin (“sfing-oh-MAI-uh-lin”) at microdomains called rafts. This compound’s biosynthesis requires a remarkable domino reaction in which (*) squalene cyclizes four times. This compound raises the melting point of phospholipids at high temperatures, but prevents bilayers from solidifying when it is cold, according to the fluid mosaic model. In the blood, this precursor to vitamin D is bound to lipoproteins like LDL. For 10 points, name this steroid found in the cell membrane. ■END■
