Uridines

Part of speech: noun

Definitions

1. A type of nucleoside formed from uracil and ribose, playing a crucial role in RNA structure and function
2. A biochemical compound that integrates into RNA, aiding in various cellular processes such as protein synthesis
3. A structural unit in nucleic acids, vital for encoding genetic information and participating in metabolic pathways

Etymology: "Uridines" is the plural of "uridine", a nucleoside, meaning a molecule made of the sugar ribose joined to the base uracil. Uridine is one of the four building blocks of RNA, the molecule that carries genetic instructions and helps build proteins, which is why the plural appears whenever chemists compare several of these units together. The name follows the standard chemical pattern for nucleosides. "Uridine" is built from "uracil", the pyrimidine base, with the "-idine" ending that marks a nucleoside, the base-plus-sugar pairing. Uracil itself takes its name from "uric acid", the compound it was first obtained from, linked to the same chemistry of urine.
