Olympicadane
Olympicadane is a mechanically-interlocked molecule consisting of five microscopic rings linked together in a linear chain to mimic the visual structure of the Olympic logo.
The chemist successfully utilized template-directed synthesis to assemble olympicadane, creating a physical manifestation of the Olympic rings at the nanometer scale

Halogenated hydrocarbon
Chlorinated solvents like chloroform are a common type of halogenated hydrocarbon, a class of chemical compounds where one or more hydrogen atoms have been replaced by a halogen such as chlorine, fluorine, or bromine.

Pentacycloanammoxic Acid
An organic molecule found in specialized bacteria, characterized by its "ladder" structure, containing two or more fused rings of cyclobutane.
Scientists recently discovered that pentacycloanammoxic acid is a key structural component of the "anammoxosome" membrane, where it helps prevent toxic leakage during anaerobic ammonium oxidation. This unique molecule contains a "ladderane" structure consisting of five fused cyclobutane rings, making it one of the most chemically strained and fascinating lipids found in nature.

Adrenocorticotropin
Adrenocorticotropin (ACTH) is a hormone produced by the pituitary gland that signals the adrenal glands to release cortisol, helping the body manage stress and metabolism. It serves as the vital chemical link in the HPA axis, maintaining balance by fluctuating in response to the body's internal clock and physical demands.
The endocrinologist ordered a blood test to measure the levels of adrenocorticotropin, a hormone produced by the pituitary gland that stimulates the adrenal cortex to release cortisol.

Dacryocystorhinostomy
Dacryocystorhinostomy (DCR) is a surgical procedure that creates a new pathway for tears to drain from the lacrimal sac into the nasal cavity.
After experiencing chronic eye infections and a blocked tear duct, the patient underwent a dacryocystorhinostomy to create a new drainage pathway between the lacrimal sac and the nasal cavity.
