Detailed explanation-1: -The Nobel Prize in Chemistry 2022 was awarded to Carolyn R. Bertozzi, Morten Meldal, and K. Barry Sharpless “for the development of click chemistry and bioorthogonal chemistry,” which involve simple, quick chemical reactions that can occur within living organisms without disrupting normal biological functions.

Detailed explanation-2: -Since 1901, the Nobel Prize has been awarded in the fields of physics, chemistry, physiology or medicine, literature and peace, while a memorial prize in economic sciences was added in 1968.

Detailed explanation-3: -In 2002, Morten Meldal and Barry Sharpless, independently of each other, developed an elegant and efficient chemical reaction: the copper catalysed azide-alkyne cycloaddition. This is now in widespread use and is utilised in the development of pharmaceuticals, for mapping DNA and creating new materials.

Detailed explanation-4: -As an open lesbian in academia and science, Bertozzi has been a role model for students and colleagues. Bertozzi was awarded the 2022 Nobel Prize in Chemistry, jointly with Morten P. Meldal and Karl Barry Sharpless, “for the development of click chemistry and bioorthogonal chemistry".

Detailed explanation-5: -In 2022, the Nobel prize for Chemistry was awarded to three laureates for the development of click chemistry and bioorthogonal chemistry, to Carolyn R. Bertozzi, Morten P. Medal, and K. Barry Sharpless.
