Choline head group. And the other is an unsaturated fatty. It uses the wiki concept so that anyone can make a contribution. Phosphatidic acid has the simplest substituent.
Phosphatidyl choline is a collective term for any phospholipid with a choline head group. Margaric acid identified by gobley in egg yolk or heptadecanoic acid h 3 c ch 2 15 cooh also belong to that class. Usually one is a saturated fatty acid in the given figure this can be palmitic or hexadecanoic acid h 3 c ch 2 14 cooh.
The french chemist theodore nicolas gobley first isolated phosphatidyl choline from egg yolk in 1847. Evidence for an orientation of the choline group perpendicular to the bilayer surface has recently been presented on the basis of t relaxation time measure ments using various shift reagents 25. Read the effect of the choline head group on phospholipid hydration chemistry and physics of lipids on deepdyve the largest online rental service for scholarly research with thousands of academic publications available at your fingertips.
For example phosphatidyl choline phosphatidyl ethanolamine and phosphatidyl serine are other common membrane lipids 4. This phospholipid is composed of a choline head group and glycerophosphoric acid with a variety of fatty acids. If correct these results mean that the presence of trivalent ions changes the choline head group structure.
Biology online is a completely free and open biology dictionary with over 60000 biology terms. These phospholipids belong to the lecithin category of yellowish brown fatty substances. Phosphatidyl choline background and benefits.
The results indicate a small spontaneous polarization of the interface 1 17 debyes per lipid molecule due to the tilting angle of the choline residue with respect to the membrane surface. Overview information choline is similar to the b vitaminsit can be made in the liverit is also found in foods such as liver muscle meats fish nuts beans peas spinach wheat germ and eggs.

Structurally pcs comprise a choline head group a glycerol body and a pair of fatty acids as tails they feature both saturated and unsaturated fatty acids. As an application we calculated the energy of interaction between an ion and the membrane polar head group region. They are an essential component in cell membranes and serve a variety of other purposes.
