Conversation

Have you ever heard of bombesin?

Yeah, I think it's something related to digestion, right?

Exactly! It's a peptide that helps release gastrin.

That's interesting! I didn't know it had that function.

Root Explanation

Bombesin is derived from the word 'bombesin' itself, which originates from the Greek word 'bombus' (meaning a buzzing or humming sound) and the suffix '-in' (used in chemistry to denote a substance). The term was first used to describe a peptide that was discovered in frog skin, which has a role in stimulating gastric secretion and has a buzzing effect on the nervous system.

Memory Tip

Think of the Greek word for buzzing ('bombus') to remember that 'bombesin' refers to a substance that has a stimulating effect, much like a buzzing sound can stimulate attention.
