Is there a difference between stomach acid and gastric juice?

Gastric acid (hydrochloric acid) in gastric juice kills bacteria in food, ensures the safety of the stomach and intestines, and increases the activity of pepsin to aid digestion. It can be seen that stomach acid is very important for the human body.

Gastric juice is a general term for gastric secretions. These include water, electrolytes, lipids, proteins, and peptide hormones. Pure gastric juice is a colorless and transparent liquid, with a specific gravity of liters, a daily secretion of liters, containing about solids, and inorganic substances are mainly Na+, K+, H+ and Cl-.

The ion concentration varies with the secretion rate of gastric juice, and when the secretion rate increases, the concentration of Na+ decreases, and the H+ increases rapidly, reaching up to 150 mgeq liters, and Cl- also increases slightly, while K+ is basically stable. H+ and Cl- combine to form hydrochloric acid. Organics include pepsinogen, mucoprotein, and "intrinsic factor".

These components are secreted by various epithelial cells in the gastric mucosal layer, parietal cells secrete HCl and intrinsic factors, and master cells secrete pepsinogen. Mucus is secreted by epithelial cells on the surface of the gastric mucosa and a small number of cervical mucus cells scattered in the fundic glands and neck, and gastrin is secreted by "G" cells. Hydrochloric acid in gastric juice activates pepsinogen to become active pepsin and creates an acidic environment for pepsin to hydrolyze proteins.

HCl also has a bactericidal effect. Pepsin activates pepsinogen. In addition to lubricating food, mucus proteins protect epithelial cells on the surface of the gastric mucosa from HCl erosion, and the "intrinsic factor" is a glycoprotein that is required for the absorption of vitamin B12 in the small intestine.

There is a difference between gastric juice and gastric acid. Gastric juice mainly includes gastric acid and peptinogen, but also includes a small amount of lipase, mucus, hormones, etc. Stomach acid is actually referred to as hydrochloric acid.

Gastric acid is hydrochloric acid, and gastric juice in addition to gastric acid also includes pepsin, intrinsic factor, etc.

Gastric acid is a component of gastric juice. Gastric juice also contains a variety of digestive enzymes.

Why is gastric juice acidic

You must have had the experience of eating too much or spitting up sour water after getting cold, and there is a part of gastric juice in sour water, so do you know why gastric juice is sour?

It turns out that the main component of gastric juice is hydrochloric acid, also known as gastric acid, which is a highly acidic substance that makes our gastric juice acidic.

The food we usually eat, although hygienic, still has some bacteria mixed in with it.

Stomach acid kills bacteria that enter the stomach with food, maintaining the stomach and small intestine'Sterile state.

Iron and calcium are essential substances for the human body, but they must be digested and absorbed well in an acidic environment.

When stomach acid enters the small intestine, the environment inside the small intestine is also acidic, which helps the small intestine absorb iron and calcium.

There is also an important substance in the gastric juice, which is called Ling and dismantled to make pepsin, which is used to digest proteins.

However, pepsin can only work in a more acidic environment, which requires stomach acid to create a good working environment for it.

The gastric mucosa has very small glands, which can be divided into rulers to secrete the stomach such as acid, enzymes, and mucus, and the mucus covers the surface of the stomach wall to protect the stomach from being eroded by gastric juice.

Gastric acid refers to the hydrochloric acid secreted by the cells of the stomach parietal. Gastric acid can increase pepsin activity to aid digestion, and pepsin is activated at an acidity of pH below 2 to break down protein for digestion and absorption. In addition, stomach acid can also kill most of the bacteria and viruses in food, ensuring that food is sterile when it enters the small intestine.

The amount of gastric acid should be controlled within a certain range, and both hyperacidity and hyposecretion of gastric acid can cause clinicopathological changes.

Gastric acid is the hydrochloric acid secreted by gastric juice, which can digest food, the stomach continues to secrete gastric acid under normal circumstances, showing diurnal changes, and its pH value is between the stomach emptying, when the food enters the stomach, gastric acid begins to secrete, and the gastric acid pH value can drop to between 2-3. The amount of stomach acid should be kept within a certain range, too much or too little will affect the digestive function.

Gastric acid refers to the secretion of hydrochloric acid in gastric juice. The human stomach continuously secretes gastric acid, and its basal excretion rate is about 10% of the maximum excretion rate, and it varies diurnal, peaking a few hours after falling asleep and lowest before waking up in the morning.

Bile reflux generally refers to the yellow bile that can be seen in the stomach cavity during gastroscopy. Consider the presence of chronic gastritis from the situation you described. It is recommended that the patient should go to the hospital if the conditions permit, undergo relevant examinations such as gastroscopy, etc., to make a clear diagnosis and choose the appropriate drug**.

Gastric acid is a secretion of the stomach and a digestive juice, and an increase or decrease in it can cause damage to the stomach. Gastric acid is mainly produced by the cells of the upper parietal walls of the stomach, which secrete high concentrations of chloride ions and hydrogen ions to make up gastric acid.

Gastric acid is a very corrosive liquid, it is found in the stomach, stomach acid can help digest food, is an important component of the digestive tract.

Gastric acid is the hydrochloric acid secreted by gastric juice, the stomach continues to secrete gastric acid under normal circumstances, showing diurnal changes, the gastric acid secretion reaches the peak within a few hours of falling asleep, and the gastric acid is the lowest in the morning.

Chronic stomach disease, excessive gastric acid secretion due to uncontrolled diet, and sensory acid reflux caused by acid reflux into the esophageal throat.

Hydrochloric acid, which is contained in gastric juice, promotes the digestion of proteins and kills bacteria.

Stomach acid is the acid reflux in the stomach, and you will have a sour feeling in your mouth.

Gastric acid, which is hydrochloric acid secreted by the cells of the stomach glands, is the main component of gastric juice. Gastric acid is secreted by parietal cells in the acid-producing glands of the stomach. Gastric acid comes in two forms in gastric juice, one is in a free state and is called free acid; One that binds to proteins to form hydrochloric acid protein salts is called conjugated acids.

The total concentration of both in gastric juice is called the total acidity of gastric juice, with free acids accounting for the majority.

Stomach. Stomach acid plays an extremely important role in the digestion of food.

Hydrochloric acid activates pepsinogen to convert it into pepsin and provides a suitable acidic environment for gastric residue piprotin to work. Kills bacteria that enter the stomach with food and water. When gastric acid enters the small intestine, it can also promote the secretion of pancreatic juice, bile and intestinal fluid, which helps the small intestine to absorb iron, calcium and other substances.

Breaks down connective tissue and muscle fibers in food, denatures the protein in food, and makes it easier to digest.

Excessive gastric acid can also cause harm to the human body, and too high gastric acid has an erosive effect on the gastric mucosa, causing inflammation or ulceration of the stomach.

HCl hydrochloride.

It is known that H+** dissociates into OH- and H2+ from water and H2O produced by oxidative metabolism of substances in parietal cells. H+ lends to be present in intracellular tubules. The H+ pump on the membrane actively transports into the tubule, and the Cl- required for the synthesis of HCl comes from plasma, which is partly diffused into the parietal cells along the concentration difference, and partly transported by the carrier.

When Cl- enters the parietal cell, it is actively transported into the tubule by relying on the Cl- pump on the intracellular tubular membrane. H+ and Cl- form HCl in intracellular tubules and then enter the gland cavity.

The main component of stomach acid is hydrochloric acid. Chemical Formula: HCl

The acid in human gastric juice is HCL (hydrochloric acid).

The acid in human gastric juice is HCl hydrochloride

Isn't it HCL in gastric juice, and what acid is there?

The stomach is an important organ in the human digestive system, it holds all the food we eat, and it also shoulders some digestive tasks. The stomach completes the task of digesting food through two pathways. The first is to use gastric juice secreted by the gastric mucosa (which contains pepsin) to digest food and degrade protein into easily absorbed substances; The second is to use gastric acid (hydrochloric acid) in gastric juice to kill bacteria in food, ensure the safety of the stomach and intestines, and increase the activity of pepsin to help digestion.

It can be seen that stomach acid is very important for the human body.

However, the amount of gastric acid in the human body can not be too much or too little, it must be controlled within a certain range, otherwise, when there is too much gastric acid, there will be symptoms such as "pyrlacic acid", "heartburn", "stomach faint disease", etc., which will reduce appetite and indigestion, and then cause gastric ulcers and other forms of gastric diseases. When there is too little stomach acid, digestion is reduced, which can lead to malnutrition.

Can you eat some sodium hydroxide to neutralize when you have too much stomach acid? No! Because sodium hydroxide has a strong corrosive effect, it can seriously damage the digestive tract when taken and cause bad results.

Doctors usually use drugs such as "baking soda" and "gastric relief". The baking soda is made of sodium bicarbonate, and the gastric solution is aluminum hydroxide. They all react ionically with the acid in the gastric juice to neutralize excess stomach acid.

When the stomach acid is too low, the doctor can usually give the patient an appropriate amount of yeast tablets to promote the secretion of gastric juice and increase appetite; You can also take an appropriate amount of dilute hydrochloric acid (about that) to adjust the pH of gastric juice to the normal range and restore the normal digestive function of the stomach.
