Question

identify the trans form of an unsaturated fatty acid.
select the correct answer below:
o ho - c - c - c - c - c - c - c - c - c - c - c - c -
o ho - c - c - c - c - c - c - c - c = c - c - c - c -
o h - o - c - c - c - c - h

Explanation:

In the trans - form of an unsaturated fatty acid, the hydrogen atoms around the double bond are on opposite sides. The second structure has a double bond (\(C = C\)) and the hydrogen atoms attached to the carbons of the double bond are on opposite sides (trans configuration). The first structure is a saturated fatty acid (no double bonds). The third structure is not a typical long - chain fatty acid structure for the context of identifying trans - unsaturated fatty acids.

Answer:

The second option (the one with the \(C = C\) double bond where the hydrogen atoms around the double bond are in a trans - like arrangement).
