Hydrolysis of marshall acid

WebHydrolysis is the cleavage of bonds in functional groups by reaction with water. This reaction occurs mainly in polymers that take up a lot of moisture and that have water-sensitive groups in the polymer backbone. Some synthetic polymers that degrade when exposed to moisture include polyesters, polyanhydrides, Web9 mrt. 2007 · The hydrolysis was inhibited by Ca cations, and to a small extent also by phosphate anions. Commercial fungal phytase (Natuphos ®) was highly active in incubations of the contents of the stomach at pH 1·9. It can be concluded that phytic acid is hydrolysed quite efficiently in the digestive tract of rabbits.
