Monosaccharides, which are the basic building blocks of carbohydrates, generally containing 3-7 carbon atoms. The carbon backbone contains many hydrophilic groups and is easily soluble in water. They constitute the basic structural units of organisms, and they are also the direct energy supply substances for metabolic activities.
Monosaccharide metabolism refers to the biochemical processes involved in the utilization, interconversion, and regulation of these single sugar molecules within living organisms. These processes encompass glycolysis, gluconeogenesis, the pentose phosphate pathway, the tricarboxylic acid cycle (TCA), and other metabolic pathways. Monosaccharide metabolism is intricately linked to energy production, carbohydrate storage, and the synthesis of complex biomolecules. By studying the metabolic pathways and dynamic accumulation changes of monosaccharides, Creative Proteomics can explore its impact on plant growth and development, stress resistance, and crop quality.
Monosaccharide Metabolism Qualitative and Quantitative Characterization: In our service, we employ cutting-edge methodologies such as high-performance anion-exchange chromatography with pulsed amperometric detection (HPAE-PAD), Ultra-performance liquid chromatography/multiple reaction monitoring mass spectrometry (UPLC-MRM/MS), and gas chromatography-mass spectrometry (GC-MS) to conduct comprehensive qualitative and quantitative analyses of monosaccharide components. These sophisticated techniques allow for the accurate identification and quantification of individual monosaccharides, providing valuable insights into their spatial distribution and relative abundance within plant samples.
Profile of Central Metabolism: our monosaccharide metabolism analysis service provides a comprehensive profile of central metabolism, encompassing key pathways such as glycolysis, the pentose-phosphate shunt, the tricarboxylic acid (TCA) cycle, nucleotide pools, and NAD-related metabolites. Through the analysis of monosaccharides and their metabolites using UPLC-MRM/MS and GC-MS methods, we offer detailed insights into the dynamics of these metabolic pathways, elucidating their regulation and interconnection within the plant metabolic network.

Case 1. Deciphering the impact of specific sugar metabolites accumulation on the growth and development of pinus massoniana seedlings: a transcriptomic combined with targeted metabolomic approach
Background:
This study delves into the molecular mechanisms governing heteroblastic transitions in P. massoniana seedlings, with a specific focus on the regulation of sugar metabolism.
The objective is to unravel the regulatory pathways of sugar metabolism amidst heteroblastic transitions in pine seedlings by elucidating the metabolic and transcriptional dynamics linked to sugar metabolism regulation during the initial phases of heteroblastic transition.
Samples:
The seeds originated from P. massoniana orchards at Duyun Ma'anshan State-owned Forest Farm, China.
After disinfection, they were germinated and grown under controlled conditions in an illumination incubator for subsequent sampling.
Technical methods procedure:
Pine seedlings at different developmental stages were selected for analysis. Leaf samples were collected from seedlings with primary needles(PN) and those with developing secondary needle buds(SNB).
Sugar metabolites were extracted from the samples using a methanol:isopropanol solution, followed by derivatization and GC-MS analysis.
Sugar contents were quantified using standard curves, and differential metabolite profiles were analyzed using statistical tests and partial least squares-discriminant analysis.
Results
The study investigated carbohydrate-related metabolite variations in primary needle (PN) and secondary needle bud (SNB) seedlings of P. massoniana.
Gas chromatography tandem mass spectrometry (GC‒MS) identified 12 carbohydrates, with PN and SNB seedlings exhibiting distinct carbohydrate profiles. Sucrose (Suc), glucose (Glc), and fructose (Fru) were predominant, with SNB seedlings showing reduced levels compared to PN seedlings.
Transcriptomic analysis revealed 103 DEGs associated with starch and sucrose metabolism pathways. Coexpression analysis identified correlations between carbohydrate contents and gene expression levels.
