Age-Related Fatty Acid Profiles in Plasma and Erythrocytes from a German Clinical Cohort

Fatty acid profiles from 1,277 patients at a metabolic disease clinic in Brandenburg, Germany. The cross-sectional study measured plasma and erythrocyte levels via gas chromatography–flame ionization detection (GC-FID) and stratified participants into five age groups. The dataset was authored by Yingqi Yu and last updated on April 10, 2026.

Use Cases

• Modeling age-related trends in omega-3 and omega-6 fatty acid levels based on the reported plasma and erythrocyte profiles.
• Analyzing associations between age and fatty acid desaturation/elongation indices (e.g., D5D, ELOVL) described in the results.
• Investigating shifts in specific fatty acids like EPA, DHA, LA, and DGLA across different age groups.
• Benchmarking proxy indices for enzyme activity in lipid metabolism studies based on the reported product-to-precursor ratios.

Strengths

• Includes data from 1,277 participants, providing a substantial sample size for analysis.
• Measures fatty acids in two biological matrices (plasma and erythrocytes), offering complementary perspectives.
• Participants are stratified into five distinct age groups (≤34, 35–44, 45–54, 55–64, ≥65 years) for comparative analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The cross-sectional design and lack of key determinants (diet, genetics, microbiome) limit causal interpretation, as noted in the discussion.
