Select ALL correctly matched fatty-acid notations.

### Why this is right - **Palmitate: 16:0**: palmitate has 16 carbons and no double bonds. - **Oleate: 18:1**: oleate has 18 carbons and one double bond. - **Linoleate: 18:2**: linoleate has 18 carbons and two double bonds. ### The concept The first number in fatty-acid shorthand is the carbon count; the second is the number of double bonds. This notation does not by itself specify the locations or geometry of the double bonds. ### The other options - **Arachidonate: 18:3**: arachidonate is 20:4; 18:3 is linolenate. ### Terms - **Palmitate**: the 16-carbon saturated fatty-acid anion. - **Oleate**: the 18-carbon monounsaturated fatty-acid anion. ### Remember Check both numbers: carbon count first, double bonds second.
