Description automatically generated


a) 16:1 (Δ9) Palmitoleic acid.

b) 18:1 (Δ9) Palmitoleic acid.

c) 16:0 (Δ9) Palmitoleic acid.

d) 16:1 (Δ10) Palmitoleic acid.

Practice: Arrange the following fatty acids from lowest à highest melting point: 18:1Δ9 ; 18:0 ; 18:3Δ9,12,15 ; 18:2Δ9,12 


a) 18:3D9,12,15 ; 18:2D9,12 ; 18:1D; 18:0

b) 18:0 ; 18:3D9,12,15 ; 18:2D9,12 ; 18:1D9

c) 18:1D; 18:0 ; 18:3D9,12,15 ; 18:2D9,12

d) 18:0 ; 18:1D; 18:2D9,12; 18:3D9,12,15

Practice: Use the provided shorthand name to draw the structure of the fatty acid myristate (14:0).
