A type of fat that is a glycerol ester of butyric acid, found naturally in butter and some other fats.
Butyrin is one of the main components that give butter its rich flavor.
Butyrin comes from the Latin word 'butyrum' (meaning butter) combined with the suffix '-in' (used to form names of substances). The word refers to a substance derived from butter, specifically a glyceride found in butterfat.
Think of 'butter' ('butyrum') to remember that 'butyrin' is a substance related to butter.
