Algae as nutritional and functional food sources: revisiting our understanding.

Journal of applied phycology

Wells ML, Potin P, Craigie JS, Raven JA, Merchant SS, Helliwell KE, Smith AG, Camire ME, Brawley SH.
PMID: 28458464
J Appl Phycol. 2017;29(2):949-982. doi: 10.1007/s10811-016-0974-5. Epub 2016 Nov 21.

Global demand for macroalgal and microalgal foods is growing, and algae are increasingly being consumed for functional benefits beyond the traditional considerations of nutrition and health. There is substantial evidence for the health benefits of algal-derived food products, but...

Re-refinement of 4xan: hen egg-white lysozyme with carboplatin in sodium bromide solution.

Acta crystallographica. Section F, Structural biology communications

Tanley SW, Schreurs AM, Kroon-Batenburg LM, Helliwell JR.
PMID: 26919531
Acta Crystallogr F Struct Biol Commun. 2016 Mar;72:251-2. doi: 10.1107/S2053230X16000777. Epub 2016 Feb 19.

A re-refinement of 4xan, hen egg-white lysozyme (HEWL) with carboplatin crystallized in NaBr solution, has been made and is published here as an addendum to Tanley et al. [(2014), Acta Cryst. F70, 1135-1142]. This follows a previous re-refinement and...

Determination of the site of incorporation of cobalt in CoZnPO-CZP by multiple-wavelength anomalous-dispersion crystallography.

Acta crystallographica. Section B, Structural science

Helliwell M, Helliwell JR, Kaucic V, Zabukovec Logar N, Barba L, Busetto E, Lausi A.
PMID: 10927374
Acta Crystallogr B. 1999 Jun 01;55:327-332. doi: 10.1107/s0108768198014414.

Data were collected from a crystal of CoZnPO-CZP {sodium cobalt-zinc phosphate hydrate, Na(6)[Co(0.2)Zn(0.8)PO(4)](6).6H(2)O} using synchrotron radiation at ELETTRA at the inflection point and 'white line' for both the cobalt and zinc K edges, and at 1.45 Å, a wavelength...

Synthesis and characterization of uranyl compounds with iminodiacetate and oxydiacetate displaying variable denticity.

Inorganic chemistry

PMID: 12005506
Inorg Chem. 2002 May 20;41(10):2799-806. doi: 10.1021/ic020121v.

Eight uranyl compounds containing the dicarboxylate ligands iminodiacetate (IDA) or oxydiacetate (ODA) have been characterized in the solid state. The published polymeric structures for [UO(2)(C(4)H(6)NO(4))(2)] and [UO(2)(C(4)H(4)O(5))](n) have been confirmed, while Ba[UO(2)(C(4)H(5)NO(4))(2)] x 3H(2)O, [(CH(3))(2)NH(CH(2))(2)NH(CH(3))(2)][UO(2)(C(4)H(4)O(5))(2)] [orthorhombic space group Pnma,...

Dearomatizing cyclization of arylsulfonylalkoxymethyl lithiums: a route to the podophyllotoxin skeleton.

Organic letters

Clayden J, Kenworthy MN, Helliwell M.
PMID: 12633083
Org Lett. 2003 Mar 20;5(6):831-4. doi: 10.1021/ol0340585.

[reaction: see text] The phenylsulfonyl group promotes the dearomatizing cyclization of tethered organolithiums onto aromatic rings. With an ether tether, the cyclizations create a new tetrahydrofuran ring, and both cyclization and subsequent electrophilic quenches proceed with high levels of...

The regioselective aminohydroxylation of allylic carbamates.

Chemical communications (Cambridge, England)

Donohoe TJ, Johnson PD, Helliwell M, Keenan M.
PMID: 12240171
Chem Commun (Camb). 2001 Oct 21;(20):2078-9. doi: 10.1039/b107253f.

The synthesis and aminohydroxylation of a series of acyclic allylic carbamates is described: the formation of a putative O=Os=NR linkage between the transition metal and substrate is proposed to account for the high levels of regioselectivity that were observed;...
