stable isotopes, how it worksFrederick Soddy, Nobel Prize in Chemistry ‐ origin and nature of isotopes (1921)Mass number and atomic number, denoted as whole numbers in superscript and subscriptHarold C. Urey, Nobel Prize in Chemistry ‐ father of modern stable isotope chemistry (1934)...
What are the stable isotopes of silicon?Isotopes:All isotopes of the same element share the common characteristic of having the same number of protons in their nuclei. This is because the number of protons determines the elemental properties of an atom. However, each isotope has a different ...
Stable isotopes are ubiquitous in nature, including all chemical compounds, the atmosphere and water resources, and therefore must exist in animals and plants. Using its physical and chemical properties to be almost the same as ordinary elements, various stable isotope labeling reagents have been prep...

What are isotopes? To complicate things a bit more, we sometimes find atoms of a chemical element that are a bit different to what we expect. Take carbon, for example. The ordinary carbon we find in the world around us is sometimes called carbon-12. It has six protons, six electrons, ...

[93] and stable isotopes [94] have demonstrated that the decrease in HDL-cholesterol in patients with type 2 diabetes is due to increased catabolism of HDLs. The activity of hepatic lipase, the enzyme controlling HDL catabolism, is augmented in insulin-resistant states, which is likely to be ...
