Metabolic Labeling

Metabolic labeling is used to probe the biochemical transformations and modifications that occur in a cell. This is accomplished by using chemical analogs that mimic the structure of natural biomolecules. Cells utilize analogs in their endogenous biochemical processes, producing compounds that are labeled. The label allows for the incorporation of detection and affinity tags, which can then be used to elucidate metabolic pathways using other biochemical analytical techniques, such as SDS-PAGE...

Zebrafish represent a powerful vertebrate model that has been under-utilised for metabolic studies. Here we describe a rapid way to measure the in vivo metabolic profile of developing zebrafish that allows the comparison of different mitochondrial function parameters between genetically or pharmacologically manipulated embryos, thereby increasing the applicability of this organism.

What is Metabolism?

2019
Overview Metabolism represents all of the chemical activity in a cell, including reactions that build molecules (anabolism) and those that break molecules down (catabolism). Anabolic reactions require energy, whereas catabolic reactions provide it. Thus, metabolism describes how cells transform energy through a variety of chemical reactions, which are often made more efficient with the help of enzymes.

In cells, critical molecules are either built by joining together individual units like amino acids or nucleotides, or broken down into smaller components. Respectively, the reactions responsible for this are referred to as anabolic and catabolic. These reactions require or produce energy typically in the form of a “high-energy” molecule called ATP. Together, these processes make up “Cell Metabolism,” and are hallmarks of healthy, living cells.JoVE’s introduction to cell metabolism briefly...

The goal of this protocol is to present a standard method to perform intravenous glucose tolerance tests (IVGTTs) to assess glycemic control in nonhuman primates and assess their metabolic status from healthy to dysmetabolic.
FAQs
Entry into an endogenous pathway is the critical first step in metabolic incorporation. Enzymes convert the supplied precursor into an activated intermediate, which can then be used during normal biosynthesis. This pathway-based processing determines whether the precursor’s atoms or functional label reach a newly produced biomolecule, linking the original chemical input with the molecule ultimately analyzed.
Activation gives the supplied precursor a chemically usable form within the cell’s biosynthetic network. Enzymatic conversion creates the intermediate that can participate in production of cellular molecules, rather than leaving the precursor as an isolated input. This step links precursor design to which biomolecules receive its atoms or label and to whether labeling can be detected.
Suitable culture conditions allow cells or organisms to continue normal biosynthesis while processing the supplied precursor. If the cells remain metabolically active, enzymes can convert the input and place its atoms or functional label into newly produced molecules. The resulting incorporation therefore depends on maintaining conditions that support both pathway activity and biomolecule production.
A typical workflow supplies a chemical precursor to living cells or organisms, allows endogenous metabolism to process it, and then examines newly produced biomolecules. Depending on the research goal, investigators may detect the label, isolate labeled material, or perform structural analysis. These stages connect precursor exposure with measurable information about biosynthesis and molecular fate.
Metabolic incorporation can place precursor-derived atoms or functional labels into proteins, nucleic acids, lipids, and other metabolites. This range lets researchers investigate labeling within different classes of newly produced cellular molecules. The selected biomolecule class determines whether the experiment emphasizes biosynthetic activity, molecular fate, detection, isolation, or structural analysis.
In chemistry and chemical biology, the strategy supports selective labeling followed by detection, isolation, or structural analysis of biomolecules. Researchers can use these readouts to measure biosynthetic activity, follow where a molecular input goes, and investigate cellular metabolism. Because labeling occurs through normal biosynthetic pathways, the approach helps study these processes without disrupting the underlying activity.
