Carbon-13-labeled compounds refer to non-radioactive-labeled compounds that use stable isotope carbon-13 instead of the original carbon. Carbon-13 labeled compounds retain the same chemical and biological properties as their unlabeled counterparts, which is significant for chemistry and Biology research. Carbon-13 can be detected by sensitive mass spectrometry technology to distinguish carbon-13 from natural carbon. Moreover, non-radioactive carbon-13 labeled compounds, including amino acids, peptides, carbohydrates, nucleic acids, lipids, steroids, vitamins, and other drugs, could be used as sensitive tracers to study organic chemical reactions and biochemical reactions more conveniently. Therefore, carbon-13 has a wide range of applications.

They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds.
Yes, grapevines are labeled as autotrophic because they are able to produce their own food through photosynthesis. They use sunlight, carbon dioxide, and water to create sugars and other organic compounds needed for growth and survival.
In general, organic compounds are those compounds which contain both carbon and oxygen, and inorganic compounds lack these atoms. Of couse, this does not always apply, as carbon dioxide and carbon monoxide also contain both these elements and are still labeled as inorganic.
Internal standards used for HPLC should possess properties such as being chemically similar to the analyte but distinguishable, not interfering with other compounds in the sample, and having a retention time different from the analyte. Common internal standards for HPLC include isotopically labeled compounds, structural analogs, or compounds that do not occur naturally in the sample matrix.
The nucleus is labeled as a.
it is labeled shut the fk up
They are labeled with a star.
An evaporating dish is a small, shallow vessel used to heat and evaporate liquids slowly. It is typically made of ceramic or glass. It can be labeled with a heat-resistant marking or have a designated area where labels can be attached.
They were once labeled group 0 in the periodic table because it was believed they had a valency of zero, meaning their atoms cannot combine with those of other elements to form compounds.
The amplitude of a wave is generally labeled 'A'.
