The antioxidant comprises one or more straight-chain or cyclic conjugated bonds constituted by conjugated double bonds.

Positive tests for double bonds and for 1,2-dicarboxylic acid

Moreover, the double lines comprising solid lines and a dotted line represent single or double bonds.)

A compound which consists of a proactive alkylating moiety containing an electron-withdrawing group, a bioreductive moiety containing at least two double bonds, and a linker joining the proactive alkylating moiety and the bioreductive moiety.

These compositions comprise at least one compound (A) containing double olefinic bonds depleted of electrons and at least one compound (B) containing double olefinic bonds enriched with electrons.

In the tissues of higher animals, additional double bonds can only be inserted between an existing double bond and the carboxyl group.

It means that these fatty acids contain many double bonds.

This type of fat contains double bonds and can be monounsaturated (one double bond) or polyunsaturated (two or more double bonds).

The invention also relates to unsaturated fatty acids comprising at least two double bonds and triglycerides having an increased content of unsaturated fatty acids comprising at least two double bonds, and the use of the same.

A saturated fat has no double bonds in its chemical structure, whereas an unsaturated fat has one or more double bonds.

Single bonds have more hydrogen molecules around them than double bonds.

Some carbon atoms are linked by single bonds (-C-C-) and others are linked by double bonds (-C=C-).[1] Double bonds can react with hydrogen to form single bonds.
