Under this second definition, polar lipids are complex lipids while neutral lipids are simple lipids. Polar lipids can contain a variety of polar groups that contribute to the charged nature of the molecule. Phospholipids contain a charged phosphate group (Figure 1), whereas glycolipids contain ...
A vague definition, instability and heterogeneity made it difficult to evaluate, let alone to isolate and characterize lipid rafts, which resulted in a great deal of controversy. Do they really exist? Can you see them? Are they cellular organelles or a cell biology concept? Do they represent ...
therefore, help stabilize the cell membrane structure. The carbohydrate constituent of a glycosphingolipid extends or protrudes on the outside of the cell membrane. Thus, glycosphingolipids are also involved in cell to cell interactions (cell adhesion) and cell recognition. ...
We consider here as a definition of the bilayer thickness (db) the center-to-center distance between lipid polar heads as obtained from a fit to the two headgroup layer positions in the NSLD profile (as illustrated in Additional file3) [29]. The error associated todbis given by the standa...
Lipoproteins Definition, Structure & Function from Chapter 9/ Lesson 4 69K Learn to define what lipoproteins are. Discover the lipoprotein structure and composition, and see the function of lipoprotein and how chylomicrons transport lipid...
See Methods for a definition of weight groups in cohort 1. Extended Data Fig. 2 Relationship between changes in lipid and participant age over time. Cohort 1 was investigated twice with approximately a 13-year interval. The open circles are the first (baseline) and the closed circles the ...
Following the definition of previous work on gene expression by Jiang et al.33 we explored the hypothesis that specific groups might present an abnormal amount of differential co-abundance. Accordingly, we discarded all metabolites belonging to the xenobiotic super classification from this analysis. To...
In subject area:Biochemistry, Genetics and Molecular Biology Cationic lipids are positively charged amphiphilic molecules constituted by a cationic polar head group (typically amino groups), a hydrophobic domain (alkyl chains or cholesterol), and a linker linking the polar head group with the non-pola...
Molecular Cell Biology A.H. MerrillJr., M.N. Vu, in Encyclopedia of Cell Biology, 2016 Definition of ‘Glycolipid’ and Subcategories of Glycolipids The term ‘glyco-’ refers to the presence of a ‘glycan’ as part of the compound, which is defined by the glossary from Essentials of Gly...
