Cholesterol s interfacial interactions with galactosylceramides |pdf=|usr=}}{{8130203 }} gab.com Text Cholesterol s interfacial interactions with galactosylceramides JO: Biochemistry http://www.kidney.de/pget.php?&tw=1&pmid=8130203 #FOAvip Recently, the influence of acyl structure on galactosylceramide's (GalCer) interfacial phase behavior was studied [Ali, S., Smaby, J. M., & Brown, R.E. (1993) Biochemistry 32, 11696-11703]. Here, we show that acyl structure is a key parameter controlling GalCer's ability to interact with cholesterol. Different chain-pure GalCer species containing saturated (24:0, 18:0, or 10:0), or unsaturated (24:1 delta 15, 22:1 delta 13, or 18:2 delta 9, 12) acyl chains were synthesized. After measurement of the force-area behavior of mixed cholesterol/GalCer films at 24 degrees C, the average molecular area and average compressibility were determined as a function of film composition. Cholesterol exerts only a slight condensing effect when the GalCer species are liquid-ordered [liquid-condensed], with maximum condensation occurring near 0.25 mole fraction. However, cholesterol exerts a marked condensing effect on liquid-disordered (liquid-expanded) GalCer species regardless of whether the acyl chain is saturated or unsaturated. Maximum condensation occurs at cholesterol mole fractions between 0.3 and 0.4. We also compared cholesterol's relative condensing effect on liquid-expanded GalCer versus sphingomyelin. Cholesterol's condensation of either bovine brain or egg sphingomyelin is 25-30% greater than that observed with different liquid-expanded GalCer species. Aside from average area behavior, we assessed cholesterol's interfacial interactions with the various sphingolipids by determining the average compressibility as a function of composition. The compressibility of condensed GalCer derivatives changes very little upon addition of cholesterol.(ABSTRACT TRUNCATED AT 250 WORDS) Twit Text FOAVip Cholesterol s interfacial interactions with galactosylceramides ????Biochemistry http://www.kidney.de/pget.php?&tw=1&pmid=8130203 #FOAvip Twit Text # Free Paper on # # # # # LINK http://www.kidney.de/pget.php?&tw=1&pmid=8130203 #FOAvip English Wikipedia <ref>{{Cite pmid|8130203 }}</ref> Cholesterol s interfacial interactions with galactosylceramides #MMPMID8130203 Ali S ; Smaby JM ; Brockman HL ; Brown RE Biochemistry 1994[Mar]; 33 (10 ): 2900-6 PMID8130203 show ga Recently, the influence of acyl structure on galactosylceramide's (GalCer) interfacial phase behavior was studied [Ali, S., Smaby, J.
