Ascientist has isolated a fatty acid that has 26 carbons. most of the carbon atoms in the fatty acid chain are connected by single bonds, except there is a double bond between the number 3 and 4 carbons as well as the number 9 and 10 carbons. the only other elements in the compound are hydrogen and oxygen. based on this information, the compound is a fatty acid.

Polyunsaturated

Explanation:

A fatty acid is a compound that is derivative from a carboxylic acid. The chain of carbons can have since 4 carbons to more than 20 carbons. The bonds between carbons can be simple, which are called saturated bonds, or double, or triple, which is called unsaturated bonds.

When a fatty acid only has saturated bonds between carbons, it's called a saturated fatty acid. If there is only one unsaturated bond, it's called an unsaturated fatty acid, and if there are two or more unsaturated bonds, it's called polyunsaturated fatty acid.

ployunsaturated fatty acid

Explanation: The presence of two double bond in the fatty acid chain makes the compound poly unsaturated. Fatty acid can either be saturated or unsaturated. Mere presence of a single double bond makes it unsaturated.
