Saturated FA vs Unsaturated FA

SN.	catagories	Saturated Fatty acids	Unsaturated fatty acids
1.	General formula	CnH2n+1COOH	Mono unsaturated FA: CnH2n-1COOH Di unsaturated FA: CnH2n-3COOH
2.	double or triple bond in their hydrocarbon tail	Absent	Present
3.	occurrence	more in animal fat	more in plant oil and fish
4.	state	Solid at room temperature	Liquid at room temperature
5.	structure	Usually straight chain	Chain bent at double and triple bond
6.	configuration	Trans- configuration	Cis- configuration
7.	Melting temperature	higher melting point	lower melting point
8.	Number of carbon atom	Even	Odd
9.	classification	i. Short chain FA (less than 6 carbon atom): examples; Butyric acid, Caporic acid ii. Medium chain FA (C8-C14): eg. Caprylic acid, myristic acid iii. Large chain FA (C16-c24); eg. Palmitic acid, steric acid	i. Mono unsaturated FA (mono ethenoid)- eg. Palmitolic acid, olic acid ii. Di Unsaturated FA (Diethenoid)-eg. Linoleic acid iii. Poly unsaturated FA (PUFA)-eg.Linolenic acid, Arachidonic acid iv. Triple bond containinf FA; eg. Nemotinic acid, Santalbic acid
10.	Health effect	Increase blood cholesterol level	Decrease blood cholesterol level
11.	Essential fatty acids	Absent	Present
12.	On exposure to air	Not affected	Solidified
13.	hydrogenation	Not affected	Converts into saturated FA
14.	sources	Cheese, butter, milk, poultry, pork	Olive oil, sunflower oil, corn oil, avocardo, salmon, tuna fish
