What is Metabolism?

What is Metabolism?

Overview of Metabolism

Overview of Metabolism

Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Introduction to Metabolism

Introduction to Metabolism

Metabolism encompasses all biochemical reactions in a living organism, facilitating both the breakdown and synthesis of biomolecules. These metabolic processes are categorized into catabolic and anabolic pathways, which operate in a coordinated manner to ensure energy balance and cellular function.Catabolic Pathways and Energy ReleaseCatabolic pathways involve the breakdown of complex macromolecules such as carbohydrates, lipids, and proteins into smaller structures like monosaccharides, fatty...

Metabolic Rate

Metabolic Rate

The human body is a powerhouse of energy, with every cell performing numerous functions that require energy. This energy production and consumption is measured by the metabolic rate, which quantifies the total heat generated by all the body's chemical reactions and mechanical work. This measurement helps to determine the rate of kilocalorie (kcal) consumption needed to fuel all ongoing activities.
The Basal Metabolic Rate (BMR) measures the energy expended at rest.
Several factors influence the...

Summary

Metabolic analysis enables comprehensive metabolome mapping by monitoring numerous metabolites. Techniques like GC-TOF-MS and HPLC/UPLC-MS provide crucial data for discovering metabolic biomarkers.

Area of Science:

Metabolomics
Analytical Chemistry
Biomarker Discovery

Background:

Metabolic analysis offers a comprehensive view of the metabolome, unlike single metabolite analysis.
High-throughput techniques are essential for monitoring hundreds of metabolites and their relative changes.

Purpose of the Study:

To detail the capabilities of various analytical techniques for comprehensive metabolic analysis.
To highlight the potential of metabolic analysis in discovering and validating metabolic biomarkers.

Main Methods:

Gas Chromatography-Time-of-Flight Mass Spectrometry (GC-TOF-MS) for small molecules.
High-Performance Liquid Chromatography/Ultra-Performance Liquid Chromatography (HPLC/UPLC) coupled with mass spectrometry (MS) for labile and nonvolatile compounds.
Direct infusion and Nuclear Magnetic Resonance (NMR) for fingerprinting and phenotyping.
