Amino acid measures

amino_acid_measures

This table stores isotopic measurements specific to individual amino acids, such as δ13C or δ15N values for alanine, histidine, and other amino acids. These measurements provide detailed insights into biochemical pathways, trophic relationships, and environmental conditions.

Sample identifier

sample_id

Sample identifier is a unique identifier assigned first by the compiler and then by the IsoArcH database to each collected sample. In each dataset, these numbers will span from 1 to n, with n representing the maximum number of samples compiled. Once in the IsoArcH database, this identifier will include the dataset number as a prefix. GRIST may automatically populate this field. Example: 1

Type	Required	Table
identifier	yes	samples, organic_measures, mineral_measures, radiocarbon_measures, amino_acid_measures

Dataset DOI

dataset_doi

This field contains the Digital Object Identifier (DOI) assigned to the dataset. It provides a unique and permanent identifier for the dataset, ensuring it can be accurately cited and easily retrieved in digital repositories associated with IsoArcH. In the case of compilations, the IsoArcH DOI also references the original source works included in the dataset, providing proper attribution and a direct link to the foundational research.
