Polyadenylation is the covalent linkage of a polyadenylyl moiety to a messenger RNA molecule. Elimination of specific hydroxyl groups on the glucopyranose moiety does not completely eliminate catalysis. Arthropod cuticle consists of chitin linked by a catechol moiety to protein. The isocyanamide functional group consists of a amino group attached to an isocyano moiety. AFP is a glycoprotein of 591 amino acids and a carbohydrate moiety. Each globin chain is associated with an iron-containing heme moiety. The principal source of the azide moiety is sodium azide. First, protein farnesyltransferase catalyzes the addition of a farnesyl moiety to the cysteine. It has a 3,5-bistrifluoromethyl benzylether piperidine in place of 2-methoxy benzylamine moiety of CP-99994 compound. However, there is also an antiaromatic lactone moiety (green). Reaction of 4 with thiourea thus leads to formation of an aminothiazole moiety. Biliverdin results from the breakdown of the heme moiety of hemoglobin in erythrocytes. Stercobilin results from breakdown of the heme moiety of hemoglobin found in erythrocytes. All three of the compounds share a common 3-trifluoromethylaniline moiety. The charged pyridinium moiety increases water-solubility.
