Final answer:
Detectors for fatty acids are mainly located in the duodenum, liver and pancreas where lipids are broken down and prepared for transport through the body's systems.
Step-by-step explanation:
The detectors for fatty acids are primarily located within the duodenum of the small intestine. Lipid metabolism begins here, where pancreatic lipase breaks down triglycerides into fatty acids and glycerol with the help of bile secreted by the liver and stored in the gall bladder. Once the fatty acids are broken down, they can be transported across the intestinal membrane, where they are recombined and then packaged into chylomicrons to be transported via the lymphatic and circulatory systems.
The detectors for fatty acids are located within the liver, duodenum, and pancreas. The liver produces bile, a digestive juice that breaks down fatty components in the duodenum. The pancreas secretes pancreatic lipase, which breaks down triglycerides into fatty acids and glycerol in the duodenum.
