Nutrient composition of mung bean
Every 100 grams of mung bean contains 23.8 grams of protein, 58.8 grams of carbohydrates, 0.5 grams of fat, 80 mg of calcium, 360 mg of phosphorus, and 6.8 mg of iron.
It also contains carotene, vitamin B1, vitamin B2, vitamin E, niacin, and a variety of mineral elements.
The protein contained in mung bean is mainly globulin, and contains methionine, tryptophan, tyrosine, and other amino acids;
Among the phospholipids contained are phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylglycerol, and phosphatidylserine.
The chemical composition of mung bean
Contains protein (mainly globulin), fat, carbohydrate, calcium, phosphorus, iron, vitamin A, B, C.
Phospholipid components include Phosphatidylcholine, Phosphatidylethanolamine, Phosphatidylinositol, phosphatidylglycerol, phosphatidylserine, and phosphatidic acid.
There are protein, fat, carbohydrates, vitamin B1, vitamin B2, carotene, niacin, folic acid, mineral calcium, phosphorus, and iron.
The protein contained is mainly globulin, which is rich in lysine, leucine, and threonine, but less methionine, tryptophan, and tyrosine.
If porridge is cooked with millet, the nutritional value can be improved. Mung bean skin contains 21 kinds of inorganic elements, with the highest phosphorus content. There are also vitexin, β-sitosterol.
Every 100 grams of mung beans contains 22.1 grams of protein, 0.8 grams of fat, 59 grams of carbohydrates, and a calorific value of 332 kcal.
The pharmacological effects of mung bean are lowering blood fat, lowering cholesterol, anti-allergic, anti-bacterial, anti-tumor, enhancing appetite, protecting liver and kidney.
Mung bean powder has a significant lipid-lowering effect. Mung bean contains globulin and polysaccharides, which can promote the decomposition of cholesterol in animals into bile acid in the liver, accelerate the secretion of bile salts in bile and reduce the absorption of cholesterol in the small intestine.
The active ingredients of mung bean have anti-allergic effects and can assist in the treatment of allergic reactions such as urticaria.
Mung bean has an inhibitory effect on Staphylococcus.
The protein and phospholipids contained in mung beans all excite nerves and increase appetite.
Mung beans are rich in trypsin inhibitors, which can protect the liver, reduce protein breakdown, reduce azotemia, and thus protect the kidneys.
Benefits of mung beans
Antibacterial and antibacterial
(1) Certain components in mung beans have a direct antibacterial effect.
(2) Indirectly exert an antibacterial effect by improving immune function.
Lower blood lipid
Studies have found that the structure of phytosterols contained in mung beans is similar to cholesterol, and phytosterols compete with cholesterol for esterification enzymes;
It can not be esterified to reduce the intestinal absorption of cholesterol, and can reduce the serum cholesterol content by promoting cholesterol alienation and/or preventing cholesterol biosynthesis in the liver.
In addition, soy globulin has been experimentally confirmed to have the effect of lowering serum cholesterol. Whether mung bean globulin has the same effect is worth exploring.
Experiments have found that mung bean has a certain preventive effect on morphine + sodium nitrite-induced lung cancer and liver cancer in mice.
Other experiments have confirmed that the phenylalanine aminolyase extracted from mung bean has a significant inhibitory effect on mouse leukemia L 1 2 10 cells and human leukemia K 56 2 cells, and the enzyme dose increases and the action time prolongs. The inhibitory effect is significantly increased. The inhibitory rate of the enzyme with 0.7U/ml for the same 48h is 52% and 14.1%, when the enzyme is increased to 3.5U/ml, it can reach 77.1% and 85.8%, respectively, and 0.20%, 1.0%, 2.0%, 4.0%, 6.0%, 10.0% of the enzymes acted on cancer cells for 72h, and the inhibition rates were 25.8%, 40.0%, 55.3%, 72.6%, 77.9%, 82.9%, respectively.
Detoxification: food poisoning
Mung bean has a detoxification effect, which mainly means that some organic compounds in the mung bean can combine with organophosphorus pesticides, mercury, arsenic, and lead compounds to form precipitates, making them difficult to be absorbed by the gastrointestinal tract, thereby detoxifying.
