'aminoacidemia' originates from 'New Latin', specifically the word 'amino acidemia', where 'amino' refers to 'amino acids' and '-emia' means 'blood condition'.

'amino acidemia' was adopted into English from medical Latin terminology, eventually becoming the modern English word 'aminoacidemia'.

Initially, it meant 'a condition involving amino acids in the blood', and this meaning has largely remained the same in modern usage.
