Describe the process of absorption of protein in the small intestine?

The small intestine is where the majority of food digestion occurs. At this point carbohydrates and proteins are already partially digested, while lipids have not yet begun. Chyme leaves the stomach and enters the duodenum (the 1st portion of the small intestine) via the pyloric sphincter. Here, maltase breaks down maltose into glucose monomers and peptidases break down peptides into amino acids. Bile is then released from the gall bladder and enters the small intestine via the bile duct to aid in the digestion of fats into glycerol and fatty acids. The chyme then enters the jejunum (the 2nd portion of the small intestine) where digestion continues and absorption begins(the jejunum is composed of many fold that increase its surface area and therefore improve absorption.) Glucose and amino acids are transported across the membrane by means of active transport (requires ATP) while glycerol and fatty acids require the help of carrier proteins (micelles (produced in the liver)) to enter the blood stream. Next, the chyme enters the ileum (the 3rd portion of the small intestine) which is mainly responsible for the absorption of select nutrients (ie. vitamin c). Once the chyme leaves the small intestine, most of the nutrients have been absorbed and only waste products and water remain; this is called liquid stool.

∙ 15y agoFood enters mouth, as it is chewed, enzymes in the saliva begins to break it down. It is swallowed, peristalsis carries it to the stomach where it comes in contact with Gastric Juices or stomach acid, mostly HCL (Hydrochloric acid). The stomach massages the now broken own food as the acid continues to break it down. Once it is broken down sufficiently (time varies) it is passed through the pyloric sphincter and into the duodenum where it is doused with bile produced in your liver but stored in your gall bladder. Bile being highly alkaline neutralizes the HCL in your stomach acid which has saturated the digested food. After this it passes through the small intesine, then the large intestine, into your colon and out of the anus, all by peristalsis.

∙ 14y agothe process of digestion has various terms toperform -
ingestion
digestion
assimilation
absorption
excretion___________________________________________________________
ingestion-
the process through an organism takes food is called as ingestion.
digestion-
when the ingested food reaches the stomach ,the proteins get broken into simpler forms through various juices.
assimilation-
when the simpler substances move to small intestine & go to various organs via blood vessels to generate energy.
absorbtion-when undigested food moves to large intestine & salt &water are absorbed.
excretion-
when the waste matter moves to the rectum & anus & is thrown out by our body time to time this is excretion.

Where does absorption of protein take place?
Within the Gastrointestinal tract of the human body
Where in the body are protein absorbs?
Nutrients are absorbed in the small intestine. Protein absorption actually begins in the stomach, and continues throughout the digestive tract. The absorption rate depends largely on the source of the protein.
Is villi located in esophagus?
No there are not. Villi are there for absorbing nutrients and protein in the small intestine and are part of absorption in the digestive system.
Is protein absorbed by the human large intestine?
Digestion of all food is completed in the small intestine, as is absorption. Large intestine is simply to pass undigested materials out of the body, and absorb what water the body requires.
What is the process that moves food from the small intestine to the blood?
The procces is called absorption. If you want to get technical, however, the name of the process depends on what the nutirent being absorbed is. For instance sodium is absorbed using a protein carrier, glucose uses that same carrier but for glucose it is called a symporter because it takes a "free" ride with sodium. Once the nutirents cross the intestinal wall they are sent to the mesenteric veins which take them to the liver and then to the circulation. If the absorbed nutrient is a big fat molecule then it takes a different path; it is picked up the the lacteals and sent directly to the circulation, thus bypassing the liver.
What is the portion of the gastrointestinal tract that absorbs food?
The process of digestion is mainly in the stomach but lots of things are also digested in the small intestine e.g. maltose into glucose (enzyme used is maltase), protein into amino acids (protease is the enzyme) and lipids into glycerol and fatty acids (lipase is the enzyme) When these have been broken down they are absorbed through the lining of the small intestine where they are absorbed into the blood (absorbtion) and used as raw materials for growth and tissue repair (assimilation). So the answer is the small intestine Hope that helped =)
Can you take whey protein with milk?
Yes you can, it gives you more protein and makes the protein absorption process slower and more constant. Personally i think it tastes better with water though.
What is celiac sprue?
Sprue-- A disorder of impaired absorption of nutrients from the diet by the small intestine (malabsorption), resulting in malnutrition. celiac sprue.occurs more widely and is due to sensitivity to the wheat protein gluten.
What are the small intestines?
The small intestine and is involved in the process of digestion. nutrients such as carbohydrates, protein, fats, and many vitamins and minerals are absorbed by your small intestine. the small intestine stretches from your stomach to the beginning of your large intestine. it is broken in to three distinct zones - the duodenum, the jejunum, and the ilium
What is the role of villi in digestive process?
J it and tujhu
What is a Zinc binding protein of intestine?
Metallothionein.
Is protein absorbed by the large intestine?
No, protein breakdown stats in the stomach and ends in the small intestine. The large intestine takes up the last of the water and produces waste from what is left that the body cannot use.
