Organic Compounds

56.2K
All living things are formed mostly of carbon compounds called organic compounds. The category of organic compounds includes both natural and synthetic compounds that contain carbon. Although a single, precise definition has yet to be identified by the chemistry community, most agree that a defining trait of organic molecules is the presence of carbon as the principal element, bonded to hydrogen and other carbon atoms. However, some carbon-containing compounds such as carbonates, cyanides, and...

Chromatographic Methods: Classification01:12

Chromatographic Methods: Classification

3.6K
Chromatographic techniques are classified in three ways: the classification is based on the physical state of the stationary and mobile phases, how the mobile phase and the stationary phase contact each other, or through the chemical or physical processes that isolate the components of the sample. Typically, the mobile phase is either a liquid or gas, while the stationary phase is either a solid or a liquid layer applied to a solid surface.
Chromatographic techniques are typically named by...

Area of Science:

  • Food Science
  • Nutritional Biochemistry
  • Neuroscience

Background:

  • Diet significantly impacts neurodegenerative diseases, yet specific food-brain connections require clarification.
  • Tomatoes are a common dietary staple with potential neuroactive constituents.
  • Understanding tomato composition is key to exploring their role in brain health.

Purpose of the Study:

  • To profile neuroactive and carotenoid compounds in different tomato varieties and processing methods.
  • To determine the influence of organic vs. conventional farming on these compounds.
  • To assess the neuroprotective potential of various tomato types.

Main Methods:

  • Liquid chromatography-tandem mass spectrometry (LC-MS/MS) for compound profiling.
  • Quantification of six carotenoids, including phytoene and lycopene.
  • Multivariate statistical analysis to identify variability drivers.

Main Results:

  • Processing and tomato variety significantly impacted compound profiles, more than organic vs. conventional production.
  • Seventy neuroactive compounds were identified, varying by type and treatment.
  • Processed tomatoes and "datterini" varieties exhibited higher levels of neuroprotective compounds compared to fresh and plump tomatoes, respectively.

Conclusions:

  • Thermal processing may enhance beneficial bioactive compounds in tomatoes.
  • Organic cultivation does not inherently increase neuroprotective compound levels.
  • Tomatoes offer a complex mix of neuroactive compounds, necessitating further research into their bioavailability and health effects.
