👉 In physics and chemistry, a pericylloid is a type of molecular orbital in which electrons are delocalized over a number of orbitals. These molecules are often found in biological systems where they play crucial roles such as hormones, neurotransmitters, and cell signaling pathways. These molecules have the property of being "pericyclic", meaning that they can be thought of as "pericylloid" molecules because their electrons are distributed over several orbitals rather than a single orbital.
