There are several different type of free fatty acids. For example, FFA1 is a free fatty acid receptor that is expressed in the pancreas and that enhances the release of insulin that is triggered by elevated blood sugar levels, leading to a more rapid restoring of a normal blood glucose level. This is an effect that can help type 2 diabetics, suffering from permanently elevated blood sugar levels but still having at least partly functional insulin secreting cells in the pancreas. Another example if FFA4, which has been found to increase the effect of insulin in the body, also an effect that may be very helpful for type 2 diabetics since the disease typically starts with a lower sensitivity of the body to insulin.
