Maltoside

Part of speech: noun

Definitions

1. A chemical compound consisting of a sugar molecule derived from maltose connected to a lipid or other hydrophobic group, often used as a detergent or emulsifier in biochemical applications
2. A molecule formed by linking maltose to a hydrophobic moiety, functioning to solubilize membrane proteins or alter surface properties in laboratory and industrial settings
3. A saccharide-based compound combining maltose units with non-polar components, employed in biochemistry for its surfactant abilities and to facilitate the study of membrane proteins

Etymology: Maltoside is a chemist's coinage, built in two steps from older scientific words. Its first part comes from "maltose," the sugar that forms when starch is broken down, which takes its name from "malt," the grain soaked and dried to start the process of brewing. The ending "-ide" is a chemical suffix used for compounds of a certain type, so the word simply names a compound derived from maltose. The sugar at the core of the word has a longer lineage. "Maltose" ends in "-ose," the standard suffix for sugars, which was borrowed through French from "glucose," itself formed from the Ancient Greek "gleukos," meaning sweet wine or must. Behind that lies an ancient Indo-European root that also produced words for sweetness, so the chemical vocabulary of sugar traces back to the sweetness of fermented drinks.

Synonyms: glycoside, disaccharide
