The significance of glucosinolates for sulfur storage in Brassicaceae seedlings

Frontiers in Plant Science, 2014
Brassica juncea seedlings contained a two-fold higher glucosinolate content than Brassica rapa and these secondary sulfur compounds accounted for up to 30 % of the organic sulfur fraction.

Can acyclic conformational control be achieved via a sulfur-fluorine gauche effect? [PDF]

, 2015
The gauche conformation of the 1,2-difluoroethane motif is known to involve stabilising hyperconjugative interactions between donor (bonding, σC-H) and acceptor (antibonding, σ*C-F) orbitals.

Remnants of an ancient metabolism without phosphate [PDF]

, 2017
Phosphate is essential for all living systems, serving as a building block of genetic and metabolic machinery. However, it is unclear how phosphate could have assumed these central roles on primordial Earth, given its poor geochemical accessibility.
