| Abstract |
Monitoring the level of glucose and glycerol or their labeled derivatives in biological fluid for kinetic studies has always been challenging, especially in mice, because of the limited volume in addition to the complexity of plasma. For such application, we developed a simple, fast, and sensitive method for the simultaneous measurement of absolute concentrations of labeled (2)H5-glycerol and (13)C6-glucose as well as endogenous D-glucose using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). In our study, 15.0 μL of mouse plasma was processed by a one-step protein precipitation, followed by LC-MS/MS analysis. The quantification of the analytes was carried out by monitoring the product ion scan of their corresponding deprotonated molecular ions and constructing the extracted ion fragmentogram by choosing a specific product ion for each analyte (equivalent to precursor ion to product ion transitions). The limit of detection (LOD) was evaluated to be 1.0 μM for both (2)H5-glycerol and (13)C6-glucose, and the limit of quantitation (LOQ) was observed to be 5.0 μM for both (2)H5-glycerol and (13)C6-glucose in diluted mice plasma that corresponds to 50 μM in plasma or 4.60 and 9.01 mg/dL of glycerol and glucose in plasma, respectively. The extraction recoveries are 81.9 % (CV = 8.1 %) for (2)H5-glycerol and 26.2 % (CV = 13.6 %) for (13)C6-glucose. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 10 November 2015.
All research outputs
#22,756,649
of 25,371,288 outputs
Outputs from Analytical & Bioanalytical Chemistry
#7,541
of 9,618 outputs
Outputs of similar age
#240,141
of 280,192 outputs
Outputs of similar age from Analytical & Bioanalytical Chemistry
#93
of 180 outputs
Altmetric has tracked 25,371,288 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 9,618 research outputs from this source. They receive a mean Attention Score of 3.1. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 280,192 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 180 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
