Gas Chromatography Detection Protocol of Short-chain Fatty Acids in Mice Feces
[Abstract] Short-chain fatty acids (SCFAs), which are formed mainly by bacteria fermenting undigested carbohydrates in the colon, they are based on the number of carbon atoms in the carbon chain. Organic fatty acids with less than 6 carbon atoms are called short-chain fatty acids. SCFAs are closely related to various aspects of the human body, so more and ...

[Abstract] Hydroxycinnamic acids, such as p-coumaric acid and ferulic acid, are a major class of compounds derived from the phenylpropanoid pathway. These compounds are widely conserved in plants and primarily accumulate in the secondary cell wall. They serve as important structural components that contribute to the overall strength and rigidity of ...
HPLC Analysis of Secreted Organic Acids
[Abstract] Under certain growth conditions some microorganisms secrete organic acids into the extracellular medium to relieve the accumulation of excess energy carriers, and/or to reduce toxic concentrations of organic acids. For example, a glycogen-deficient ∆glgC mutant of the cyanobacterium Synechococcus sp. PCC 7002 secretes pyruvate, ...
Citrus Fruit Ascorbic Acid Extraction and Quantification by HPLC
[Abstract] Citrus are among the most relevant sources of vitamin C (ascorbic acid + dehydroascorbic acid). Recent studies have revealed that it increases in the peel as fruit ripens and remains constant or even decreases in the pulp tissue. Moreover, important differences on ascorbic acid content exist among citrus varieties in both tissues. Here we describe ...
