DHHC domains attach one of these compounds to a cysteine residue, increasing affinity for structures made of them. For 10 points each:
[10m] Name these compounds added to proteins via palmitoylation. Triton-X-100 can be used to isolate microdomains named for these compounds.
ANSWER: lipids [or fatty acids; accept phospholipids or sphingolipids; accept lipid rafts]
[10e] Though most molecules in lipid rafts lack it, lipids with this property may be degraded into peroxide derivatives by interacting with free radicals. Hydrocarbons with this property have at least one double or triple bond.
ANSWER: polyunsaturation [accept word forms like polyunsaturated; accept monounsaturation]
[10h] Lipid peroxidation can be measured with this assay, which uses thiobarbituric acid to measure the production of harmful aldehydes like MDA by reactive oxygen species.
ANSWER: TBARS assay [or thiobarbituric acid reactive substances assay]
