Identification of S-1-propenyl-L-cysteine as the catalytic product of AfGGT1 and a key intermediate in isoalliin biosynthesis in Allium fistulosum. L [PDF]
Our findings reveal that pyruvic acid content is generally higher in Allium fistulosum than in A. cepa. In A. fistulosum, the bulbs contain more pyruvic acid than the leaves, while in A.

Preparation of (+)-trans-isoalliin and its isomers by chemical synthesis and RP-HPLC resolution. [PDF]
Naturally occurring (+)-trans-isoalliin, (R(C)R(S))-(+)-trans-S-1-propenyl-L-cysteine sulfoxide, is a major cysteine sulfoxide in onion. The importance of producing it synthetically to support further research is very well recognized. The (+)-trans-isoalliin is prepared by chemical synthesis and reversed-phase (RP)-HPLC. First, S-2-propenyl-L-cysteine (

Changes of S-alk(en)ylcysteine sulfoxide levels during the growth of different garlic morphotypes
The contents of three S-alk(en)ylcysteine sulfoxides (alliin, methiin, and isoalliin) were determined in the leaves, pseudostems, and bulbs of six garlic genotypes (two flowering plant morphotypes, two semi bolters, and two scape absent morphotypes ...

Allium discoloration: the nature of onion pinking and garlic greening
Precursors involved in the formation of pink and green-blue pigments during onion and garlic processing, respectively, have been studied. It has been confirmed that the formation of both pigments is of a very similar nature, with (E)-S-(1-propenyl ...
