from The American Heritage® Dictionary of the English Language, 4th Edition
- n. Any of a group of organic compounds, including the fats, oils, waxes, sterols, and triglycerides, that are insoluble in water but soluble in nonpolar organic solvents, are oily to the touch, and together with carbohydrates and proteins constitute the principal structural material of living cells.

- n. Any of a group of organic compounds including the fats, oils, waxes, sterols, and triglycerides. Lipids are characterized by being insoluble in water, and account for most of the fat present in the human body. They are, however, soluble in nonpolar organic solvents.

- n. Any of a variety of oily or greasy organic compounds found as major structural components of living cells; they are insoluble in water but soluble in organic solvents such as alcohol and ether, and include the common fats, cholesterol and other steroids, phospholipids, sphingolipids, waxes, and fatty acids; some of the lipids, together with proteins and carbohydrates, form an essential structural component of living cells, as in the cell walls and membranes. The term lipid refers to its solubility in nonpolar solvents, and has no significance with regard to chemical structure.

Hemolysis, jaundice, changes in lipid profile, oxidative stress, renal dysfunction and death
Nearly all heart attack survivors benefit from long-term lipid therapy.
I thought I might exploit lateral diffusion in lipid layers for the purpose.
The big problem with live originating in lipid vesicles is that they are impermeable and would thus need channels that could not have evolved in an abiotic environment (i.e. a classical irredcuible complex system which is abviously contradictory to gradual evolution).
These techniques range from simple calcium phosphate precipitation to sequestering the plasmid DNA in lipid vesicles that fuse to the cell membrane and deliver the contents to the cytoplasm (as illustrated in Figure 8).
I chose Hanahan as my thesis advisor and became immersed in lipid chemistry, particularly in the metabolism of phospholipids.
Researchers said the lipid could be an important compound for a new class of anti-viral drugs.
Three years ago,my brother-in-law was started on a brand name lipid lowering medications.
I believe it was George Mann who called the lipid hypothesis the biggest fraud ever perpetuated on the public.
To make this idea a bit clearer, Poletti said that scientists know that in the early earth, DNA which is a form of stored information and memory somehow managed to get inside membranous enclosures called lipid sacs.
