Unsaturated fatty acids are often classified according to the number of carbon atoms between the terminal methyl carbon (the omega carbon) and the closest double bond to the methyl end of the chain. an omega 6 fatty acid, for example, would have a double bond in positon 6 counting from the methyl end of the molecule.

classify,

gamma-linolenic, arachidonic acid, eicosapentaenoic acid(epa), palmitoleic acid, linoleic acid, oleic acid, and alpha-linolenic acid

into the following categories: omega-3, omega-6, omega-7, or omega-9.

i think it is true in my reasonment ..

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

currents is the correct answer.
