Root Explanation

Allantoin is derived from the Greek word "allantois" (meaning sausage or sausage-like), which refers to a substance found in the allantoic fluid of embryos. The suffix "-in" is commonly used in chemistry to denote substances, particularly proteins or alkaloids. Thus, allantoin refers to a substance that is similar to or derived from the allantois.

Memory Tip

Think of the Greek word for 'sausage' ('allantois') to remember that allantoin is a substance related to the allantoic fluid, which is found in embryos.
