Generally, stable isotope tracers are substrate-specific. Labeled fatty acids are used to assess fat metabolism, deuterated glucose tracers are used to measure carbohydrate metabolism and labeled ...

A potential problem is that nitrogen is a building block of proteins and therefore may succumb to protein catabolism occurring during migration, which can cause increased nitrogen isotope ...

and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element. For example, most carbon (≈ 99 %) has 6 protons and 6 neutrons and is written ...

Stable isotope techniques are useful for the evaluation of food fortification programmes or dietary diversification strategies. Protein bioavailability from plant foods to maintain and optimize the ...

"Our study not only adds to our understanding of how tooth enamel records an animal's Sr isotope exposure, but also helps to reconstruct animal migrations from Sr isotope analysis," lead author ...

Researchers carried out stable isotope analysis, focusing on various isotopes of carbon and nitrogen to study the protein portion of his mother’s diet. The mix of isotopes from these elements ...

Stable isotopes are non-radioactive forms of atoms. Although they do not emit radiation, their unique properties enable them to be used in a broad variety of applications, including water and soil ...
