This is ace: a 1927 letter to the Journal of Biological Chemistry from George William Clough. GW Clough had written to J Biol Chem to explain that Levene and Haller were wrong to state that he (GWC) had come to the oppposite conclusion as them – in fact, he agreed with the result that Levene and Haller had obtained. I love that J Biol Chem have this on their site. There’s lots more too – if you ever wondered about the hydrogen ion determination of normal saliva or the observations on the nature of the sugar of normal urine, then look no further (than the link at the bottom of this page).
There’s also a couple of PDFs on the J Biol Chem page linked to below that might be of interest to the McKeiths and Holfords of this world – Zinc and normal nutrition looks interesting and I reckon McKeith would love to hear about nutritive properties of the mung bean. (Incidentally, McKeith was on Jonathon Ross’s show last Friday and I was, um, less than totally impressed by her abilities. She complained that Wossy’s poo-sample-in-a-plastic-box smelt disgusting: “eurgh, I can smell that through the box”. Wossy’s poo was actually a mashed-up Mars bar. So either Mars bars smell like shit or McKeith talks shit).
Edited to add another link: The origin of homochirality.
