Acyl group - Wikipedia
In chemistry, an acyl group is a moiety derived by the removal of one or more hydroxyl groups from an oxoacid, [1] including inorganic acids. It contains a double-bonded oxygen atom and an organyl group ( R−C=O ) or hydrogen in the case of formyl group ( H−C=O ).
Acyl Group Definition and Examples - ThoughtCo
2019年5月6日 · Acyl Group Definition. An acyl group is a functional group with formula RCO- where R is bound to the carbon atom with a single bond. Typically the acyl group is attached to a larger molecule such that the carbon and oxygen atoms are joined by a double bond.

21.1 Naming Carboxylic Acid Derivatives - Organic Chemistry
If an alkyl group is attached to one of the phosphate oxygens, it is identified after the name of the acyl group. In biological chemistry, acyl adenosyl phosphates are particularly common. A summary of nomenclature rules for carboxylic acid derivatives is given in Table 21.1.

21.2: Nucleophilic Acyl Substitution Reactions
Carboxylic acid derivatives tend to undergo a reaction called nucleophilic acyl substitution. In the same fashion as nucleophilic addition, this mechanism starts with a nucleophilic attack on an electrophilic carbonyl carbon, forming a tetrahedral alkoxide intermediate.
