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. (20[1])This molecule’s polar -OH (20[1])(“O-H”) group orients with sphingomyelin (“sfing-oh-MAI-uh-lin”) at microdomains called rafts. This (20[1])compound’s (0[2])biosynthesis (20[2])requires (20[1])a remarkable domino reaction in which (*) squalene (10[2])cyclizes (10[3])four (10[1])times. This (10[1])compound raises the melting point of phospholipids at high (10[1])temperatures, (10[3])but prevents bilayers (10[2])from solidifying (10[1])when it is cold, (10[3])according (10[1])to the fluid mosaic (10[1])model. In the blood, this precursor (0[1])to vitamin D is bound to lipoproteins like LDL. For 10 (10[1])points, (10[1])name this steroid (10[1])found in the cell (10[1])membrane. (10[1])■END■ (10[3]0[1])
