Sphingolipids examples
WebOxygen is more electronegative then hydrogen, and will 'hog' the electrons if you will. This will cause the oxygen to be slightly negatively charged while the hydrogen is slightly positively charged. As Sal said in this video, charged particles dissolve in water, so this will be hydrophilic. This is different with CH3 groups. WebGlycolipids are a type of complex lipids comprising carbohydrates, fatty acids, sphingolipids or a glycerol group. The term glycolipids mainly describe any compound containing one or …

WebSphingomyelin can comprise as much as 50% or more of the lipids in certain tissues, though it is usually lower in concentration than phosphatidylcholine. For example, it makes up about 10% of the lipids of brain, where it is a key constituent of myelin, but 70% of the phospholipids of the human lens.
