Q:Is urea an inorganic salt?

Is not organic matter ah inorganic salts are present in the body and food minerals in the mineral, composed of organic matter and inorganic synthesis of the human body has been found to have more than 20 kinds of essential inorganic salts, about 4 to 5% of body weight. More (> 5g) for calcium, phosphorus, potassium, sodium, chlorine, magnesium, sulfur seven; daily dietary requirements are more than 100mg, known as constant elements. Other low content, with the modern analysis of technological progress Iron, copper, zinc, manganese, cobalt, molybdenum, selenium, chromium, nickel, silicon, fluorine, vanadium and other elements were found by atomic absorption spectroscopy, neutron activation, plasma emission spectroscopy and other trace analysis methods. But also the human body is necessary, the daily dietary requirements for the amount of μg ~ mg called trace elements.

Q:Which crop feet can provide C N inorganic salts for fungal growth

Plant growth requires a variety of inorganic salts, which require the most is nitrogen, phosphorus, potassium containing inorganic salts. If a lack of some inorganic salts, plants can not grow normally. Kind of crops need fertilization, farm manure contains organic matter, the microbial decomposition of the soil will produce a large number of inorganic salts for plant growth and utilization, the role of fertilizer is to provide a variety of plant growth of inorganic salts. Therefore, in agricultural production, the application of fertilizer and farm manure is intended to provide a variety of inorganic salts for crops.

Q:Octopus why the lack of boron-containing inorganic salts can cause rape to flow only without fruit

When the boron deficiency occurs, pollen tube germination is affected and poor fertilization leads to seed formation.

Q:What are the effects of water, inorganic salts, carbohydrates, proteins, fats and vitamins?

The main physiological function of fat: 1. The supply of human heat. (Per gram of fat oxidation can produce 9 kcal of calories, protein and carbohydrates produce more than 2 times.) 2. constitute the body's adipose tissue, adjustable body temperature, To prevent the body outside the scattered, to protect the internal organs, moisturizing the skin. 3. Dissolve nutrients. (Some do not dissolve in water and only soluble in lipids, only in the presence of fat can be absorbed by the body.

Q:Can inorganic salts be tested by LC / MS?

LC-MS mass spectrometer for organic matter, inorganic salts can not be atomized not applicable, and will pollute the instrument.

Q:What are the nutritional requirements for bacterial growth?

For water: the nutrients required for bacteria must be dissolved in water, nutrient absorption and metabolism are required to carry out water.

Q:Which foods contain calcium-containing inorganic salts

Calcium and inorganic salts are two concepts, bother you to go back and turn the chemical book and then ask, inorganic salt can eat

Q:TRUE OR FALSE: the addition of salts to water will always increase the surface tension of water. explain.?

False. Although inorganic salts will increase surface tension of the water by increasing the attractive forces between water molecules on the surface, organic salts will typically (always?) decrease the surface tension.

Q:Children eat what to add the body of inorganic salts

Such as fruits, vegetables, beans or soy products, kelp, eggs and so on. Eat hot and humid food: watermelon, bitter gourd, peach, ebony, strawberry, tomatoes, cucumber, mung bean and so on.

Q:What is the risk of low inorganic salt?

Phosphorus into the body of phosphorus containing 750-800mg about 1% of body weight, mineral weight of 1/4. Of which 87.6% in the form of hydroxyapatite bone salt stored in the bones and teeth, 10% with protein, fat, sugar and other organic matter combined constitute soft tissue, the rest distributed in the muscle, skin, nerve tissue and other tissues and membranes Of the ingredients. Function Phosphorus is present in every cell of the human body, which is indispensable for bone growth, tooth development, renal function and nerve conduction. Phosphorus is a component of nucleic acids, phospholipids and certain enzymes, which promotes growth and tissue repair. It helps carbohydrate fat and protein utilization, regulates glycogen breakdown, and participates in energy metabolism. Phospholipids are the major components of the cell membrane, which are related to the permeability of the membrane. Phosphate can regulate the metabolism of vitamin D, to maintain the stability of calcium within the environment. Lack of disease  phosphorus deficiency when the mental confusion, cranial nerve palsy, transport disorders, muscle weakness, hypothyroidism, anorexia, joint stiffness, abnormal blood, urinary calcium increased. Typical cases  hyperphosphatemia, renal dysfunction, or hypoparathyroidism and hypothyroidism and other endocrine diseases can also occur. Too many symptoms  nerve excitement, tetany and convulsions. The physiological requirement of phosphorus is 12.3mg / kg / d. Calcium / phosphorus ratio in the 2: 1-1: 2 appropriate range. Food sources  food in the meat, fish, milk, beans and hard shells and other phosphorus more.
