The Protist Kingdom consists of mostly unicellular organisms that can have characteristics similar to plants, animals or fungi. Characteristics of Protists: mostly unicellular, few multicellular, eukaryotic, can be heterotrophic or autotrophic.Ex: algae, Paramecium, kelp (multicellular). î î î.he Protist Kingdom consists of mostly unicellular organisms that can have characteristics similar to plants, animals or fungi.

The active metabolites of codeine, notably morphine, exert their effects by binding to and activating the Î¼-opioid receptor. This occurs because opioids structurally mimic endogenous endorphins which are naturally found within the body and also work upon the Î¼-opioid receptor set.
However, in recent years, evidence indicating that GSH conjugation plays an important role in the formation of toxic metabolites from a variety of chemicals has accumulated. Thus, several classes of compounds are converted, via conjugation with GSH, into either cytotoxic, genotoxic, or mutagenic metabolites.ompounds that form GSH conjugates are processed by gamma-glutamyl transpeptidase (gamma-GT) and dipeptidases to cysteine S-conjugates, which are usually excreted in urine as their corresponding mercapturic acids (S-substituted N-acetyl-L-cysteine conjugates).
