Definitions
from The American Heritage® Dictionary of the English Language, 5th Edition.
- noun 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.

- noun (Chem., Biochem.) 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 , andfatty 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 termlipid refers to its solubility in nonpolar solvents, and has no significance with regard to chemical structure.

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).
