Metabolic problems of the three major nutrients in humans and animals

The prepared digestive juice may be: pancreatic juice, intestinal juice and bile vegetable oil are hydrolyzed and must be emulsified by bile, and then catalyzed by lipase or intestinal lipase to decompose into glycerol and fatty acids.

Judging from the experimental phenomenon, it shows that the vegetable oil is digested. Then there must be bile in this digestive juice, which is used to emulsify fats. At the same time, pancreatic juice and intestinal juice can digest fat.

The digestion of fat is mainly in the small intestine, and the digestion and absorption are special. Since fats are insoluble in water, and enzymatic reactions in the body take place in aqueous solutions, fats must be emulsified before they can be digested. Bile salts from the gallbladder play an important role in fat digestion by first purifying the fat and reducing its surface tension, and then emulsifying the fat into very fine emulsified microparticles.

Pancreatic juice contains lipase, which is broken down by lipase. The products of decomposition are diglycerides, monoglycerides, fatty acids, and glycerol. Short-chain fatty acids of less than 12 carbon atoms are directly absorbed by the lining of the small intestinal mucosa.

Long-chain fatty acids are then esterified into triglycerides, which combine with cholesterol, lipoproteins, and phospholipids to form chylomicrons that enter the lymphatic system, and finally enter the bloodstream, where they are transported to various tissues of the body. Of all the lipids in foods, only cow's milk is rich in short-chain fatty acids, which are transported through the lymphatic system. The absorption of long-chain fatty acids is in the small intestine through the intestinal mucosa into the terminal lymphatic vessels of the intestinal mucosa, and then re-lipo with glycerol in the lymphatic vessels, and the resynthesis of triglycerides occurs.

Lipids that are liquid at body temperature are well digested and absorbed, while many lipids that have a melting point above body temperature are difficult to digest and absorb. Therefore, some animal fats that remain solid at 37 degrees are difficult for the human body to absorb.

So the digestive juice contains pancreatic juice than bile salts used to turn fat into granules. Pancreatic juice contains lipase, which is broken down by lipase. The products of decomposition are diglycerides, monoglycerides, fatty acids, and glycerol.

Humans and animals cannot use inorganic substances such as carbon dioxide and water to make organic matter like green plants, they must ingest food from the outside world to obtain nutrients and energy, this type of nutrition is called heterotrophic.

A metabolic mode in which an organism is metabolized during assimilation. Organic matter cannot be synthesized directly from inorganic substances, and only ready-made organic nutrients can be ingested from the outside world. Heterotrophs include humans, animals, and parasitic, saprophytic plants.

Symbiosis of humanity.

There are countless bacteria and other microorganisms in the human digestive tract. In fact, food residues excreted by humans are mainly produced by the decomposition of food by bacteria. These bacteria have a variety of functions, but their primary duty is to break down the substances inside the digestive tract, and without them, the human digestive tract would not be able to do this task.

For example, large amounts of undigested carbohydrates enter the gut, and bacteria in the gut can break them down into various acids that can be absorbed and converted. In this way, the body uses bacteria to digest and get more nutrients and calories from food, while bacteria in the digestive tract (intestines) get stable food through the body**.

Summary. The basic metabolic characteristics of aquatic animals for the three major nutrients are as follows:1

Carbohydrate metabolism: Aquatic animals can use carbohydrates as energy** and store them as liver glycogen for emergencies. Some fish such as carp, crucian carp and snails, coffee, octopus, etc., can digest starch and glucose.

2.Protein metabolism: Protein is an important component in the body of aquatic animals, which contains many essential amino acids, which cannot be synthesized by passive objects themselves.

Therefore, aquatic animals need to maintain their normal growth and metabolic needs through the protein in their food. At the same time, aquatic animals can also produce new proteins and amino acids through metabolism in the body to meet the needs of their biological functions. 3.

Lipid metabolism: The ability of aquatic animals to metabolize lipids varies from species to species, for example, fish have a high level of body fat crystals.

The basic metabolic characteristics of aquatic animal dry fluid for the three major nutrients are as follows:1Carbohydrate metabolism:

Aquatic animals can use carbohydrates as energy** and store them as liver glycogen for emergencies. Some fish such as carp, crucian carp and snails, coffee, octopus, etc., can digest starch and glucose. 2.

Protein metabolism celery: Protein is an important component in the body of aquatic animals, which contains many essential amino acids, which cannot be synthesized by passive objects. Therefore, aquatic animals need to maintain their normal growth and metabolic needs through the protein in their food.

At the same time, aquatic animals can also produce new proteins and amino acids through metabolism in the body to meet the needs of their biological functions. 3.Lipid metabolism:

The ability of aquatic animals to metabolize fatty substances varies from species to species, for example, fish have a higher amount of body fat crystals.

I'm sorry I don't understand, but can you elaborate on that?

Summary. Hello dear, happy to answer your <>

Nutrition refers to the various substances contained in food that contribute to the growth and development of humans and animals, and maintain the normal physiological functions of the body. Nutrients mainly include six categories: carbohydrates, proteins, fats, vitamins, minerals, and water. Specifically, these nutrients have the following physiological effects in humans and animals:

2.Protein: It is an important substance for the composition and repair of human tissues, and it is also the basis for the formation of biomolecules such as enzymes.

4.Vitamins: Most vitamins are essential nutrients that can be used to maintain various physiological functions in the body and help prevent certain diseases.

5.Minerals: They are important components in the human and animal bodies, and when consumed through food and drink, they can help maintain vital functions and ensure the balance of various chemical reactions in the body.

6.Water: About 70% of the body's weight is made up of water, which is a key component in most life processes, used to maintain water balance in the body, maintain a normal temperature, and transport nutrients and waste.

Summary. Hello, dear, <>

It is clarified that the interconversion process of the three major nutrients in animals is that sugars and proteins can be converted into each other in vivo. Almost all of the natural amino acids that make up proteins can be deamination to form nitrogen-free fractions that can be converted into sugars; The intermediates of carbohydrate metabolism can form non-essential amino acids through amino acid conversion. Note:

Essential amino acids cannot be formed in the body through aminoconversion.

Dear, <>

The relationship between carbohydrate metabolism and lipid metabolism The intermediates of carbohydrate metabolism can be converted into fats, and glycerol and fatty acids produced by lipolysis can also be converted into sugars. Sugars can be converted into fat in large quantities, but fats cannot be converted into sugars in large quantities. The relationship between protein metabolism and lipid metabolismIn general, fat in animals cannot be converted into amino acids, but it can be converted in some plants and microorganisms; Some amino acids can be converted into glycerol and fatty acids in different ways, which in turn can be used to synthesize fats.

Dear, <>

In higher animals, the metabolism of the three major categories of substances of carbohydrates, lipids and proteins is carried out at the same time, and they are both interrelated and mutually restrictive, which is a coordinated and unified process. 1. Similarities in the metabolism of the three major nutrients (1) The three major nutrients have three pathways: digestion and absorption in food, transformation of other substances, and decomposition of their own substances.

2) All can be used as energy substances The three major nutrients can be oxidized and decomposed in the body and used as energy substances. But they are supplied in order, they are supplied in the order of sugars, lipids, and proteins. (3) In animals, sugars can be directly converted into proteins and fats, and proteins can also be directly converted into sugars and fats, but fats cannot be directly converted into proteins.

4) Metabolic end products The sum is the same metabolic end product of the three major nutrients.
