Digestion is the process of breaking down food bile salts, pepsin, and lipase 2 down chemical and physical processes of digestion chemical and physical . The family of bile acids includes a group of molecular species of acidic steroids with very peculiar physical-chemical and biological characteristics they are synthesized by the liver from cholesterol through several complementary pathways that are controlled by mechanisms involving fine-tuning by .
Physical vs chemical digestion the process of breaking down foods in the elementary track to gain nutrients in the food is known as digestion the obtained nutrients in this process are then absorbed into the circulatory system and circulated all over the body with the blood. Physical vs chemical digestion physical digestion physical digestion involves breaking food down into smaller pieces without making any chemical changes. Describe the digestive roles of the liver, pancreas, and gallbladder a process called emulsification bile is a mixture secreted by the liver to 22 chemical . Bile acts by breaking apart particles of fat into much smaller bits, giving the fat a much greater surface area for enzymes to act the bile does not change the fat chemically though, it just breaks it apart, so bile uses a physical process.
Lab 8 - chemical and physical processes of digestion 2106 words | 9 pages i will define key terms that describe what will occur in the experiments i will conduct an experiment for each activity and provide all resulting data as well as answer questions from each activity. Physical activity and c- physical change d- chemical change e- physical change 2 change in color, gas, light or smoke and heat pieces before we swallow it . Synthesis, physicochemical properties, and biological activity of bile acids 3-glucuronides: novel insights into bile acid signalling and detoxification. All four of these bile acids can be taken back up into the blood stream, return to the liver, and be re-secreted in a process known as enterohepatic circulation  . Mechanical digestion is a purely physical process that does not change the chemical nature of the food instead, it makes the food smaller to increase both surface area and mobility instead, it makes the food smaller to increase both surface area and mobility.
Up to 95% of the secreted bile salts is reabsorbed from the gut, not together with the products of lipid digestion, but through a process called enterohepatic circulation.
