Fatty acid synthase (FAS) is an important enzyme in the synthesis of long-chain saturated fatty acids. It
can catalyze malonyl coenzyme A, acetyl coenzyme A and NADPH to produce long chain fatty acids and
NADP+. NADPH has a characteristic absorption peak at 340nm. The activity of FAS can be calculated by
measuring the decreasing rate of absorbance at 340nm.
Reagents and Equipment Required but Not Provided:
Ultraviolet spectrophotometer, desk centrifuge, pipette, water bath/ incubator, 1 mL quartz cuvette, mortar/
homogenizer, ice and distilled water.
