Liquid compositions are described which are acidic and which comprise an alkyl hydroperoxide or an organomineral hydroperoxide.

The inactivator is ideally a hydroperoxide.

The lipid may be a HDL hydroperoxide.

Total organic peroxides, expressed as cumene hydroperoxide

The organic peroxide is preferably a hydroperoxide.

The sec-butylbenzene is then oxidized to produce a hydroperoxide and the hydroperoxide is decomposed to produce phenol and methyl ethyl ketone.

Isopropyl cumyl hydroperoxide, not more than 72% in diluent type A

The oxidation reaction product may have at least 50 wt% of cyclohexylbenzene, no greater than 80 wt% of cyclohexyl-1-phenyl-1-hydroperoxide, and 0.1 wt% to 10 wt% of another hydroperoxide.

Cumyl hydroperoxide, not more than 90% in diluent type A

This system includes a metal; a peroxide, hydroperoxide or mixture thereof; and a reductant.

p-Menthyl hydroperoxide, not more than 72% in diluent type A

The present invention relates to fatty acid 13-hydroperoxide lyase proteins which have been modified with respect to a previously described guava 13-hydroperoxide lyase and the nucleic acid sequences encoding these proteins.

Unlike other ferric hemoproteins, hemerythrin binds oxygen by forming a hydroperoxide complex ROOH.

The improvement also relates to decomposing a secondary hydroperoxide by contacting the secondary hydroperoxide with a catalytic amount of a heterogeneous catalyst of Zr or Ti hydroxide or oxide.

Expression systems for recombinant guava 13-hydroperoxide lyase and methods of using recombinant guava 13-hydroperoxide lyase for the production of green notes are provided.
