Mucic acid, pronounced /ˈmjuːsɪk ˈæsɪd/, is a type of dicarboxylic acid that is commonly used in the production of nylon. The spelling of the word "mucic" comes from the Latin word "mucus," meaning "mucus" or "slime," which references the sticky or syrupy nature of the acid. The pronunciation of the word is phonetically broken down as /muːs/ (like "moose") + /ɪk/ (rhymes with "tick"). With its unique spelling and usage in industrial chemistry, mucic acid is an important component of many products and applications.
Mucic acid is a crystalline compound with the molecular formula C6H10O8. It is a white solid substance that is soluble in water and has a sweet taste. Mucic acid is derived from the oxidation of certain sugars, such as galactose and mannose. It is commonly used in chemical laboratories as a reagent for the identification and quantification of sugars.
In terms of its chemical structure, mucic acid belongs to the group of dicarboxylic acids, meaning it contains two carboxyl functional groups (COOH). These groups contribute to its acidity and ability to act as an acid in chemical reactions. Mucic acid can be classified as a non-toxic substance and is generally considered safe to handle.
One of the significant applications of mucic acid is in the identification of galactosemia, a genetic disorder characterized by the inability to metabolize galactose, a sugar found in milk products. By observing the formation of mucic acid when galactose is oxidized, healthcare professionals can diagnose the presence of galactosemia in individuals.
Additionally, mucic acid has industrial uses in the production of certain food additives, pharmaceuticals, and for the synthesis of other organic compounds. Its properties make it useful in various fields, including biochemistry, medicine, and chemical analysis.

The word "mucic acid" derives from Latin. It comes from the Latin term "mūcus", meaning "mucus" or "slime". The term "acid" was added to indicate its acidic properties.
