'allomucic' originates from 'Greek', specifically the word 'allos' meaning 'other' and 'mucic' from 'mucus', where 'mucic acid' is a derivative of 'mucus'.

'allomucic' changed from 'mucic acid' and eventually became the modern English word 'allomucic'.

Initially, it meant 'a derivative of mucic acid', and this meaning has largely remained the same in modern usage.
