molecular massThe structures and masses of amino acids and their more common modified forms (posttranslational and artificial) are presented as aids to analysis of polypeptides by mass spectrometry.doi:10.1007/BF02760777James P. TurnerBryan John Smith...
Mass spectrometry is a powerful analytical technique often used for the identification of unknown compounds such as small organic molecules, nucleotides, oligonucleotides, and peptides as well as proteins.
For example, protein compositions are restricted to combi- nations of amino acids and certain modifications. This greatly limits the composition space that must be searched and reduces the likelihood of ambiguity in deducing composition. Furthermore, even a non-defin- itive result may be very ...
crystals were obtained in the absence of additives. Whereas, fan-shaped crystals were produced when P5 was added (Supplementary Fig.8). These results proved that the emergence of fan-shaped crystals was attributed to the presence of chiral additives but not merely the chirality of amino acid ...
Compare that with how your body works. There is a protein that builds your body: the ribosome. It's a molecular machine that decodes messenger RNA and assembles amino acids to build peptides. And it does it in a fundamentally digital way, in exactly the sense of Shannon and von Neumann...
(2018) found that deep-sea microorganisms produce transporters not only for substrate such as amino acids and carbohydrates, but also for osmolytes. These osmolyte transporters increase with depth, reaching 39% of protein sequences identified in the bathypelagic zone. Recently, Saw et al. (2020) ...
the solution thus obtained with a compound having an unbranched carbon chain of at least six carbon atoms selected from the group consisting of amines, amino acids, acid amides, and a product of reaction between amines, amino acids and acid amides with an alkylene oxide, and mixtures thereof....
