蛋白

蛋白 is the Chinese term for 'protein,' a vital nutrient composed of amino acids that the body uses to build and repair tissues, produce enzymes and hormones, and support immune function.

The character 蛋 (dàn) originally meant 'egg' and later came to represent 'protein' in scientific contexts. 白 (bái) means 'white' or 'pure.' Together, they literally translate to 'white substance,' which refers to the white part of an egg, where protein is primarily found.

In daily life, 蛋白 is commonly used in nutrition and food science contexts. It is also used in scientific and medical discussions. For example, people may refer to 'high-protein diets' as 高蛋白饮食. The word is often seen on food labels and in health-related conversations.
