20 aragonite samples were precipitated in vitro from seawater between September 2021 and December 2022. The data contains amino acid compositions for samples precipitated with and without specific biomolecules like aspartic acid and glycine. Researchers from the British Geological Survey collected this data to study how calcification fluids affect aragonite precipitation.
Use Cases
- Compare amino acid composition between control samples and those precipitated with 2 mM aspartic acid (Asp) or glycine (Gly).
- Analyze the effect of the dipeptide glycyl-L-aspartic acid (Asp-Gly) on aragonite's amino acid profile.
- Investigate compositional differences in samples precipitated with tetra-aspartic acid (Asp4) versus single amino acids.
- Study the relationship between biomolecule concentration in seawater and the resulting aragonite amino acid data.
Strengths
- Data covers 20 distinct aragonite samples precipitated under controlled laboratory conditions.
- Includes comparisons across multiple biomolecule treatments: Asp, Gly, Asp+Gly, Asp-Gly, and Asp4.
- Samples were analyzed both as free amino acids and as hydrolysed samples to detect peptides.
Limitations
- Small sample size of 20 limits statistical power for detecting subtle effects.
- Data is restricted to in vitro precipitation, which may not fully replicate natural biomineralization processes.
- Specific column names and data structure are unknown, complicating direct analysis.
