THE identification of non-volatile organic acids on paper chromatograms is usually dependent on the use of a suitable pH indicator which is applied to the developed and dried paper by spraying 1.

A METHOD for the identification of volatile fatty acids by means of paper chromatography was reported by Hiscox and Berridge 1. In this method the acid was applied as the ethylamine salt to the ...

Proteins are made of strings of amino acids that resemble the strand in the image above. Using machine learning models, researchers were able to design the identity of amino acids on a computer to ...

This folds into existing research, like a 2017 paper suggesting that our amino acids represent the best of the best, not just a “frozen accident” of circumstances. In the new paper ...
