structural lipids containing phosphate

Phospholipids are substances that contain fatty acids, glycerol, a nitrogenous base and phosphoric acid. They are found in virtually every type of cell and are a key component in all cellular membranes controlling what substances pass through the cell membrane. Phospholipids are completely compatible with the natural lipids found in epidermal layers of the skin. As skin cells die in the natural process of keratinization, this balance is upset, and need to be restored in order to regenerate. if the phospholipids-cholesterol balance is not restored, new cells will not regenerate or will regenerate more slowly.

Fats containing phosphorus.

A chemical compound consisting of phosphoric acid, fatty acids, and nitrogen.

Used for its essential fatty acid properties.

Cellular materials that contain phosphorus and are soluble in organic solvents. An example is lecithin (phosphatidyl choline). Phospholipids are important constituents of cellular membranes. (See lipids.)

The major class of lipids present in biomembranes, usually composed of two fatty acid chains esterified to two of the carbons of glycerol phosphate, with the phosphate esterified to one of various polar groups. ( Figure 5-27)

Any lipid that contains phosphorus. They are the major lipids in cell membranes.

Are fatty substances that are a major component of myelin.

A lipid molecule with an attached phosphate group. Lipids with a phosphate group in place of one of the three fatty acid chains. Phospholipids are the building blocks of cellular membranes. Phospholipids have hydrophilic heads (glycerol and phosphate) and hydrophobic tails (the non-polar fatty acids).

Phospholipids are important for building up the cells of an organism. They have a double function as physiological agents in metabolism and as biological emulsifiers. Phospholipids are similar in structure to triglycerides (fats), but one fatty acid is replaced by a phosphate group. Most phospholipids also have a more or less large functional group (e.g. choline or serine). This structure makes them more polar (hydrophilic) than triglycerides and enables them to mediate between polar and non-polar substances: they are emulsifiers. The best-known phospholipid is probably lecithin. Whether naturally present in the flour or added subsequently, phospholipids have positive effects on the properties of the dough and on baked volume. They also help to maintain the softness of the crumb. _Top of page

Asymmetrical lipid molecules with a hydrophilic head and a hydrophobic tail. Lipids with a phosphate group in place of one of the three fatty acid chains. Phospholipids are the building blocks of cellular membranes. Phospholipids have hydrophilic heads (glycerol and phosphate) and hydrophobic tails (the non-polar fatty acids). PICTURE

A greasy or waxy compound found particularly in the membranes of the red blood cells.

Fatty acids combined with the mineral phosphorus and other molecules that make up the lining of a cell membrane.

Make up the fat portion of cell membranes.

fats containing groups called phosphate groups. They make up cell walls (membranes) and are also important in the body's metabolic processes (chemical reactions).

A class of molecules containing a polar head group that contain phosphorus atom and two non-polar hydrocarbon chains. They are the primary constitiuents of liposomes (lipid vesicles). There are many phospholipids due to the variuos possible types of head groups and hydrocarbon chains of different lengths.

Any lipid consisting of a phosphate group and one or more fatty acids.

molecules of fat in cell membranes.

Lipids (fat molecules) in which phosphoric acid as well as fatty acids are attached to a glycerol backbone. Phospholipids are found in all living cells and in the bilayers of cell membranes.

Lipids containing one or more phosphate groups, and are of great importance for the structure and function of cell membranes. Phosphorylated To add a phosphate group to (an organic molecule).
