The gut microflora metabolize the bile acids produced by the human host. Their enzymes catalyze the deconjugation of the bile acids, that is, removal of the taurine and glycine groups. These enzymes also catalyze dehydroxylation, converting cholic acid to deoxycholic acid. Gut bacteria convert bile acids to compounds that appear to be carcinogenic and possibly contribxite to cancer of the colon. 

The biomedical use of polyphosphazenes for drug delivery and controlled release systems still draws considerable attention. It has been demonstrated for the degradable polymer [NP(NHCH2C02Et)2]n that the rate of degradation increases by partially replacement of the ethyl glycinate groups by small amounts... 

The most important conjugation reaction is with glucuronic acid to form a glucuronide. Other conjugations occur with sulfate, acetyl, methyl and glycine groups.

The transitions at 226 and 266 nm can be interpreted as the charge transfer transition from n-pair of oxygen atom to the coordination bond 0 -l -I. Under the coordination the partial negative charge is transferred to the molecular iodine, as evidenced by the appearance 228 nm corresponds a charge transfer transition from the molecular iodine to the protonated glycine group. 

Other enzymes in the soluble fraction of liver and kidney then remove the gluta mate and glycine groups to form cysteine derivatives which in turn are acetylated to form mercapturic acids. 

Many other materials are described in the literature, including glycine groups (NH2CH2COOH) and polyvinylidene fluoride (PVDF) which has a rather low pyroelectric coefficient but is useful because it can be used to make inexpensive, small-area thin films.
