General description
2,3-Butanedione, a volatile compound, is a product of citrate metabolism that is generally produced by certain bacteria including Lactococcus lactis ssp. diacetylactis and Leuconostoc citrovorum. It has a typical buttery flavor and is commonly found in fermented dairy products, such as sour cream, yogurt and cottage cheese.
Application
2,3-Butanedione may be used as an analytical standard for the determination of the analyte in milk and human breath samples by solid-phase microextraction and gas chromatography.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Members of the superfamily of solute carrier (SLC) transmembrane proteins transport diverse substrates across distinct cellular membranes. Three SLC protein families transport distinct neurotransmitters into synaptic vesicles to enable synaptic transmission in the nervous system. Among them is the SLC17A6/7/8
