Digestion of fats and other lipids begin in the small intestine and relies on the production of bile. Bile contains salts, which act as detergents (emulsifiers) that aid in digestion and absorption of lipids. In the small intestine many nutrients leave the intestine through the bloodstream, some products of fat (triglyceride) take a different path: After being absorbed by epithelial cells, fatty acids and monoglycerides (glycerol joined to a single fatty acid) are recombined into triglycerides within those cells. These fats are then coated with phospholipids, cholesterol and proteins forming water-soluble glubules called chylomicrons. These globules are too large to pass through the membranes of capillaries. Instead they are transported into a lacteal, a vessel at the core of each villus of the intestinal wall. Lacteals are part of the vertebrate lymphatic system.
Digestion of carbohydrates start in the mouth. Amylase, an enzyme in saliva, hydrolyzes starch and glycogen into smaller polysaccharides. This digestion continues in the stomach after the food (bolus) passes through the esophagus. In the stomach, gastric juice that have two components finishes the digestion of the carbohydrates before the intestine absorbs the broken down molecules through capillaries in the villus, before being diffused or pumped into the bloodstream. One of the components of gastric juice is HCI, which disrupts the extracellular matrix that binds cells together. Pepsin is the other component, but is more relevant in the digestion of proteins.
What else can I help you with?
What is the mammalian digestive system composed of?
fist the stomach where the digestion of proteins starts second the pancreas which secretes pancreatic juice which helps in the digestion of fats proteins and carbohydrates third the bile which is made by the liver and emusifies the fats fourth the duodenum where the digestion of fats starts also digestion of proteins and carbohydrates takes place fifth the small intestine where absorption takes place note digestion of carbohydrates starts in the mouth
What is the small intestine useful for?
The small intestine is useful for the Digestion of fats, proteins and carbohydrates contained in the foods you consume, is completed within the small intestine.
What is digestion in simple words?
Digestion in humans is the process by which nutrients such as proteins, fats, and carbohydrates in the food consumed are broken down to its respective components.
What do the chemical structures of carbohydrates and fats have in common and how do they differ?
(mostly) composed of C, H and O
What product of digestion is not normally released directly into the bloodstream?
The product of digestion is not normally released directly into the bloodstream is fats. Fats have to be broken down by the liver.The products of digestion that is not normally released directly into the bloodstream is fats. On the other hand, carbohydrates, minerals and vitamin C are digested and released directly into the bloodstream.fat
Which procedure would have the least effect on the rate of protein digestion?
Consuming protein with carbohydrates or fats slows down the rate of protein digestion because they require different enzymes to break down in the stomach. Eating protein-rich foods alone, without carbohydrates or fats, would have the least effect on the rate of protein digestion.
What is the pancreases function in digestion?
it secretes digestive enzymes that are important to the digestion of carbohydrates, fats(lipids), anf proteins. it also secretes a alkaline based juiced that is filled with a bicarbonate.
In what order do fats carbohydrates and proteins in a mouthful of food begin going through chemical digestion?
carbohydrates- 1st in mouth due to saliva proteins- 2nd in stomach due to enzymes fats- 3rd in small intestine due to bile
What does salivary enzymes do?
Salivary enzymes help to break down carbohydrates and fats in food during the process of digestion. They begin the chemical breakdown of food in the mouth, specifically targeting starches and some fats. This process aids in the overall digestion and absorption of nutrients in the body.
Name the end products of digestion for the following types of foods?
starch-glucose2. protein-amino acids3. fats-fats4. sugar-glucose
Can digestion occur if you remove the stomach?
no. you would die. Actually, most digestion occurs in the small intestine anyway. Some proteins may not be properly digested, but carbohydrates and fats would be.
How is the chemical digestion of carbohydrates brought about?
Enzymes which are involved in the digestion of carbohydrates.
