Lipids are insoluble, so they will form a layer on top of the water, much like when oil from a spillage will float above the water's surface, as it is less dense than the water. They will not dissolve.
They form micelles. This is the first step in the making of soap. See saponification.
The formation of micelles is also the first step towards the creation of the Cell Membrane's "bi-lipid layer."
they float on the surface. think of oil in water
mix? repel?
Emulsion
lipids are waterproof so the water just slides right off.
Water is polar, but lipids are nonpolar.
Lipids are hydrophobic or ambiphilic small molecules. In water, hydrophobic lipids such as oils and fats clump up and separate from the water. In water, ambiphilic lipids such as phospholipids form bilayer structures; the body of living creatures uses these bilayer structures to form cell membranes and vesicles.
Lipids are non-polar molecules that DO NOT usually dissolve in water but DO usually dissolve in organic solvents. Lipids are fat molecule and think about adding eg oil (fat) to water. They don't mix. You always need an emulsifier (eg soap)
Lipids
Lipids do not absorb water
No. Lipids do not dissolve in water.

Lipids Lipids
Sugar water does NOT contain lipids!Unless it is not just sugar water.
This is possible only if the ratio of lipid is massive to the ratio of water. However, this is usually not the case. In most cases, when lipids and water are mixed, the hydrophobic properties of the lipids cause the lipids to coalesce at the top of the water without mixing, because that lipids are less dense than water.

lipids show a strong response to water. The tails don't react to water, and the heads "love" water.
An important feature that all lipids have in common with one another is they are hydrophobic structures.
