21. The free carboxyl groups interact with cations to form insoluble pectic acid divalent metal ion complexes. 22. Carboxyl groups are less reactive than primary amines, making C-terminomic techniques more complex than established N-terminomic approaches.23. It is only when the carboxyl group is removed that the THCA becomes THC, which is psychoactive. 24. Propylene glycol alginate is alginic acid that has some of its carboxyl groups esterified with propylene glycol. 25. Sodium bicarbonate reacts with carboxyl groups in proteins to give a brisk effervescence from the formation of. 26. Whereas a non-participating group, a group usually without a carboxyl group , will often result in an ?-glycoside. 27. The hCPT s hydroxyl has less inductive effect on the carboxyl group which makes the lactone very reactive. 28. Pectin methyl-esterase is the enzyme responsible for hydrolyzing carboxymethyl esters and liberating free carboxyl groups and methyl alcohols. 29. Salicylic acid has the carboxyl group . 30. In this reaction, the lone pair on the adjacent Tyrosine hydroxyl abstracts the proton off the carboxyl group .
