The prefix "albumin-" is typically associated with which type of substance?

The prefix "albumin-" is associated with proteins, specifically a group of proteins that are soluble in water and have the ability to coagulate when exposed to heat. Albumins are important components found in various biological fluids, most notably in blood plasma and egg whites. They play vital roles in maintaining osmotic pressure and transporting various substances within the body. The connection between "albumin-" and proteins emphasizes the significance of these molecules in biological processes, making proteins the correct identification for this prefix. The other categories like sugar, fat, and mineral each have distinct prefixes and terminologies associated with them, which do not relate to the concept of albumins.
