The structure of the acetoxy group blue. In organic chemistry, the acetoxy group (abbr. AcO or OAc; IUPAC name: acetyloxy [1]), is a functional group with the formula −OCOCH 3 and the structure −O−C(=O)−CH 3. As the -oxy suffix implies, it differs from the acetyl group (−C(=O)−CH 3) by the presence of an additional oxygen atom.
The technique was introduced in the field of peptide synthesis by Robert Bruce Merrifield in 1977. [111] For peptide synthesis via automated machine, the orthogonality of the Fmoc group (basic cleavage), the tert‑butyl group (acidic cleavage) and diverse protecting groups for functional groups on the amino acid side-chains are used.

Bikini waxing is the removal of pubic hair using a special wax, which can be hot or cold, that adheres to hairs and pulls them out when the wax is removed quickly from the skin, usually with a cloth strip. While the practice is mainly associated with women, male waxing has become a more common practice to remove men's pubic hair. [1]
One technique for reducing the clitoral hood is the bilateral excision (cutting) of the prepuce tissues covering the clitoral glans, with especial attention to maintaining the glans in the midline. [6] Another technique cuts away (excises) the redundant folds of clitoral prepuce tissue, with incisions parallel to the long axis of the clitoris. [7]
Functional group interconversion can be used in retrosynthetic analysis to plan organic synthesis. A functional group is a group of atoms in a molecule with distinctive chemical properties, regardless of the other atoms in the molecule. The atoms in a functional group are linked to each other and to the rest of the molecule by covalent bonds.
In IUPAC nomenclature, an acetyl group is called an ethanoyl group. An acetyl group contains a methyl group ( −CH 3 ) that is single-bonded to a carbonyl ( C=O ), making it an acyl group . The carbonyl center of an acyl radical has one non-bonded electron with which it forms a chemical bond to the remainder (denoted with the letter R ) of the ...
The fluorenylmethoxycarbonyl protecting group (Fmoc) is a base-labile amine protecting group used in organic synthesis, particularly in peptide synthesis. [1] It is popular for its stability toward acids and hydrolysis and its selective removal by weak bases, such as piperidine , without affecting most other protecting groups or sensitive ...
Threading a southeast Asian hair removal method. This semi permanent hair removal method is done when a cotton thread is pulled alongside the skin, removing the hair in a straight line. This removal technique is used for small areas of the body, such as for facial hair - especially eyebrows. Results last for up to 3 weeks. [4]
