Ions formed in the ion source are separated according tom/zvalues in a mass analyzer. The termmass analyzeris in common use, although more correctly it would be termed anm/z analyzergiven the fact that mass spectrometers separate ions according tom/z,not mass. This chapter will use the terms...
Molecular weight, mass of a molecule of a substance, based on 12 as the atomic weight of carbon-12. It is calculated in practice by summing the atomic weights of the atoms making up the substance’s molecular formula. The molecular weight of a hydrogen m
Chaperones have been grouped into families based on their molecular mass, common domains, protein structure similarity, and common function1. Families composing the main chaperone machinery, which modulate protein structure without participating in the final protein complex, include prefoldin7, the small ...
Themolecular weight(or relative molecular mass) of a substance is the mass of its molecules relative to that of other molecules. The datum formolecular weightsis carbon-12, and this is given amolecular weightof 12. All other elements and compounds have molecular weights relative to this, and ...
There is increasing evidence that many risk loci found using genome-wide association studies are molecular quantitative trait loci (QTLs). Here we introduce a new set of functional annotations based on causal posterior probabilities of fine-mapped molecular cis-QTLs, using data from the Genotype-Tiss...
1. What is the molecular mass of methanol? Methanol: Methanol is a chemical compound. This means it is made up of two or more chemical elements that are bonded together. The chemical formula for methanol is CH3OH. This means that in one molecule of methanol, there are 4 atoms of hydroge...
Fundamental problems faced by the protocells and their modern descendants include how to go from one phenotypic state to another; escape from a basin of attraction in the space of phenotypes; reconcile conflicting growth and survival strategies (and ther

so that transitions between states of unequalJshow a step-ladder pattern in the separation of lines of the same series. Because of the large value of the moments of inertia, due to the mass of the nucleus, the separation of these states is small, of order 0.01eV, increasing with increasin...
MALDI and LD-MS are methods normally used to generate molecular ions from large MM, thermally labile molecules, described inChapter 8, Analytical techniques for high mass materials: method development. However, MALDI-MS can be used at low laser power to produce mass spectra of small aromatic mol...
