Hormonal Control of Myo-inositol Incorporation into Pectin

Hormonal control of myo-inositol incorporation into pectin.

The rate of incorporation of glucose into the galacturonic acid residues of pectin has been shown to be modified by the auxin, indoleacetic acid (1). In recent experiments, Loewus, Kelly, and Neufeld (2, 3) have shown that myo-inositol is also a good precursor of the uranic acid of pectin. These workers suggest that myo-inositol is oxidatively cleaved to form glucuronic acid. The latter might b...

Inositol-phosphodihydroceramides in the periodontal pathogen Tannerella forsythia: Structural analysis and incorporation of exogenous myo-inositol

BACKGROUND Unique phosphodihydroceramides containing phosphoethanolamine and glycerol have been previously described in Porphyromonas gingivalis. Importantly, they were shown to possess pro-inflammatory properties. Other common human bacteria were screened for the presence of these lipids, and they were found, amongst others, in the oral pathogen Tannerella forsythia. To date, no detailed study...

Role of myo-inositol

Characterization of agonist-stimulated incorporation of myo-[3H]inositol into inositol phospholipids and [3H]inositol phosphate formation in tracheal smooth muscle.

The effects of the muscarinic agonist carbachol, histamine and bradykinin on incorporation of [3H]inositol into the phosphoinositides and the formation of [3H]InsPs were examined in bovine tracheal smooth-muscle (BTSM) slices labelled with [3H]inositol. These agonists result in substantial and dose-related increases in the incorporation of [3H]inositol into the phospholipids. Carbachol and hist...
