Examples of monounsaturated fatty acids are



A Oleic acid
B Arachidonic acid

C Linolenic acid
D Palmitic acid

Ans. A Oleic acid

• Classification of unsaturated fatty acids: - i.e. FA contain 1 or 2 or more double Bonds

1. Monounsaturated FA Monoenoic acid one double bond.

Eg.Palmitoleic acid series ω7, C18

Oleic acid series ω9, C18

Elaidic acid series ω9, C18

Erucic acid Series ω9; C22

Nervonic acid series ω9, C24

2. Polyunsaturated fatty acids - contain two or more double bond: eg.

[A] Dienoic acids two double bonds - eg. Linoleic acid series ω6, C18

[B] Trienoic acid Three double bonds

eg . -Linolenic acid ω9, C18

-Linolenic acid ω9, C18

[C] Tetra enoic acids 4 double bonds eg. Arachidonic acid ω6, C20

[D] Pentaenoic acids 5-d.b

eg. Timnodonic acid ω3, C20

Clupanodonic acid ω3, C22

[E] Hexaenoic acids 6-d-b eg. Cervonic acid ω3, C22

Series w classification of unsaturated fatty acids:

iω9 omega-nine eg. oleic, Elaidic, Erucic, Nervonic acids.

iiω7 omega seven eg: Palmitoleic acid.

iiiω6 omega six γLinolenic, Linoleic, Arachidonic.

ivω3 omega-three — a-Linolenic, Timnodonic, Clupanodoic, Cervonic acids.

Saturated fatty acids: - contain no double bonds: -

eg. formic C1- Acetic C2 Propionic C3 Butyric C4Valeric C5caproic C6caprylic acid C8Capric

C10Lauric C12Myristic C14Palmitic C16 Stearic C18Arachidic C20Behenic C22Lignoceric C24
