Not all lipids are saturated. Unsaturated lipids come in liquid form and are not from animals. Saturated lipids are in solid form and do usually come from organisms other than plants such as animals.
Lipids are soluble in organic solvents and insoluble in water .They store large amount of energy .
There are six types of lipids: Fatty Acids Unsaturated Saturated Monosaturated Polysaturated Triglycerides
One property of dietary lipids is that Omega-3 fatty acids are always unsaturated. Acetic acid is the simplest form of fatty acid.

Double bonds
The difference is related to which long chain fatty acid is incorporated. If it is a fatty acid that has double bonds, then it is an unsaturated lipid. If it contains fatty acids that have no double bonds, then it is a saturated lipid.
-anoic = saturated -enoic = unsaturated -ate = charged carboxylic group
If there are no double bonds, then carbon will take up as many hydrogens as it can, two (three on the ends). Because there are more hydrogens bonded, they are referred to as "saturated" lipids. Unsaturated lipids have double bonds between the carbons and hydrogens. When there is a double bond, one carbon only bonds with one hydrogen - "unsaturated" lipids. The double bonds cause "kinks" in the fatty acid tails, so it is more difficult to "pack" them together. For this reason, they do not solidify at room temperature. However, saturated lipids may solidify at room temperature -- this is how you distinguish between saturated and unsaturated lipids by sight. Examples of saturated lipids (having no double bonds between carbons and hydrogens) are animal fats. "Saturated fats" is a synonym for animal fat on nutritional labels.
Lipids that are saturated do not have double bonded hydrogen atoms to the carbon skeleton of the molecule. Instead, the molecule has all of its available spaces filled with hydrogen atoms that are bonded to each open carbon atom of the molecule. To make it simple, saturated lipids are saturated with hydrogen.
If a lipid is saturated, then it is a saturated fat and is solid at room temperature (saturated means it has the maximum number of hydrogen atoms attached to the carbon atoms in the atomic structure). If the lipid is unsaturated, then it is an oil that is a liquid at room temperature. Remember: lipids are a broad term covering any fat soluble substances such as fats, oils, fat soluble vitamins, waxes, etc.
1.Saturated fat is solid fat at room temperature whereas unsaturated fat is liquid at room temperature. 2. Saturated fat is single bond fat whereas unsaturated fat is double or triple bond fa t. 3.Saturated fat is animal fat whereas unsaturated fat is plant fat. 4. Saturated fat can engender severe diseases if taken in excess whereas unsaturated fat is not harmful if taken in excess but is merely stored as subcutaneous fat.
