The influence of pentose on breath methane. 1981

L F McKay, and W G Brydon, and M A Eastwood, and J H Smith

In a population study the concentration of methane in the expired breath of methane-producing subjects was significantly related to the dietary intake of noncellulosic polysaccharide pentose (p less than 0.01) and to the intake of lignin (p less than 0.05). The single dose administration of complex polysaccharide sources rich in pentoses to fasting subjects did not result in an increase in methane production when measured over 5 h. The single dose administration of D(+) xylose and L(+) arabinose led to a significant increase in methane excretion in methane producers.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
D008031 Lignin The most abundant natural aromatic organic polymer found in all vascular plants. Lignin together with cellulose and hemicellulose are the major cell wall components of the fibers of all wood and grass species. Lignin is composed of coniferyl, p-coumaryl, and sinapyl alcohols in varying ratios in different plant species. (From Merck Index, 11th ed) Lignins
