unsaturated.
polyunsaturated
A fatty acid contains double bonding within its carbon
double carbon carbon bonds
Saturated fatty acids have no double bonds between the individual carbon atoms of the fatty acid chain; the chain of carbon atoms is fully "saturated" with hydrogen atoms.A fat molecule is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond; where double bonds are formed, hydrogen atoms are eliminated
There may be one double bond or many, up to six in important fatty acids.
polyunsaturated
A saturated fatty acid chain is composed of a carbon chain with only single covalent bonds. This creates a tetrahedral geometry of the atoms. An unsaturated fatty acid chain is composed of a carbon chain with one or more double covalent bonds. This creates a trigonal geometry of the atoms at the double covalent bond.

double carbon carbon bonds
Having double covalent bonds in the carbon chain.

polyunsaturated
Saturated fatty acids have no double covalent bonds between carbon atoms. The carbon in the chain is saturated with all the hydrogens it can hold. Saturated fatty acids account for the solid nature at room temperature of fats such as lard and butter. Unsaturated fatty acids have double bonds between carbon atoms wherever the number of hydrogens is less than two per carbon atom. Unsaturated fatty acids account for the liquid nature of vegetable oils at room temperature.
There may be one double bond or many, up to six in important fatty acids.
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.
Carbon containing acids are weak acids and fatty acids for example some fatty acids are in meat
A triglyceride contains three fatty acids that are composed of hydrogen, carbon and oxygen. In a single free fatty acid if there is a hydrogen missing from the carbon chain creating a double bond then it is considered to be unsaturated. Adversely, saturated fat contains no missing hydrogens.
