Biochemical characterization of the antioxidant system in the Antarctic scallop Adamussium colbecki, a sentinel organism. The dataset contains baseline measurements of glutathione levels and enzyme activities in digestive glands and gills, along with seasonal variation data from spring and summer. It was produced by the organization SCIOPS and sourced from NASA's Earthdata platform.
Use Cases
- Establish baseline levels for glutathione, glutathione reductase, and catalase activity in gill tissue for future pollution impact studies.
- Analyze seasonal variations in Total Oxyradical Scavenging Capacity (TOSC) measurements between spring and summer months.
- Correlate activity levels of Se-dependent glutathione peroxidases and superoxide dismutase across different tissue types (digestive gland vs. gills).
- Model oxidative stress susceptibility using the measured activities of glyoxalase I, glyoxalase II, and glutathione S-transferases.
Strengths
- Data covers multiple antioxidant system components: glutathione levels and 8 distinct enzyme activities.
- Includes measurements from two key tissues (digestive gland and gills) and two seasonal periods (spring and summer).
Limitations
- Sample size and number of individual specimens measured are unknown.
- Geographic coverage is limited to the Antarctic environment where Adamussium colbecki is found.
