A type of protein fragment produced during digestion, formed when proteins are broken down by enzymes.
From hetero- (different) + albumose (a protein derivative). The term combines Greek heteros (other/different) with albumose, which comes from Latin albus (white), referring to the white appearance of albumin proteins.
Scientists realized that when your stomach breaks down proteins, it doesn't make just one product—it makes several different intermediate fragments, including heteroalbumose. This discovery was crucial to understanding digestion before we could study proteins at the molecular level.
