Table 2. ACSL enzyme activity in pure beta cells is concentrated in insulin secretory granules and mitochondria.

ACSL enzyme activity was measured with palmitate as a substrate as described under Material and Methods. The specific enzyme activity of the homogenate of whole cells is defined as 1.

Cellular Fraction Relative Specific ACSL Activity/mg Protein
Homogenate of whole cells 1
Insulin Secretory Granules 4.1
Mitochondria 1.9
