isoleucine
Essential protein component
Isoleucine is one of the essential amino acids—building blocks of protein that the human body cannot synthesize and must obtain from food.
It plays a role in muscle metabolism, immune function, and energy regulation.
Meat, fish, eggs, and dairy are rich sources.
The name reflects its structural similarity to leucine, another amino acid.
