Diabetes - Non Esterified Fatty Acids (NEFA)

Non-esterified fatty acids (NEFA) are molecules released from triglycerides by the action of the enzyme lipase and are transported in the blood bound to albumin. They contribute only a small proportion of the body’s fat, however they provide a large part of the body’s energy. Measurement of NEFA is important in diabetes where insulin deficiency results in the metabolism of fat. Levels are also frequently increased in obese patients.
