គន្លឹះរក្សាសុខភាពឆ្អឹង-Tips for Healthy Bone

You can read the below steps to keep your bones healthy! 

Your bones must get the calcium and phosphorus they need from your diet. Phosphorus is plentiful in most foods, so it is unusual to run low on this mineral. However, it is important to make sure you eat and drink plenty of calcium. Good sources of calcium are milk, dairy products, and leafy green vegetables. The more, the better! Also, getting enough sunlight (but don’t get sunburned!) is important. You see, when our skin is exposed to sunlight, vitamin D is produced. Vitamin D helps your intestines take in calcium from the food you eat.

  • dairy products អាហារដែលផលិតពីទឹកដោះគោ
  • leafy green vegetables បន្លែស្លឹកពណ៌បៃតង
  • intestine ពោះវៀន
  • exposed to ត្រូវ, ប៉ះនឹង


Another thing that keeps bones healthy is exercise. The stresses that are placed on bones as you run or play sports, lift weights, walk, or run help keep them strong. Because your bones are designed to detect how strong they need to be, weight-bearing exercise (like running, but not swimming) actually causes the osteoblasts to make your bones stronger.

Chemical Reactions and Energy

Image
Synthesis Reactions A chemical reaction occurs when atoms, ions, molecules, or compounds interact either to form or to break chemical bonds. Reactants are substances that enter into a chemical reaction, whereas the substances that result from the chemical reaction are called products. A synthesis reaction is when two or more reactants chemically combine to form a new and larger product. The synthesis reactions occurring in the body are collectively referred to as anabolism. These reactions produce the molecules characteristic of life, such as ATP, proteins, carbohydrates, lipids, and nucleic acids. Some conditions of the body such as growth, maintenance, and repair could not take place without anabolic reactions. Synthesis reactions in which water is a product are called dehydration (water out) reactions. Decomposition Reactions A decomposition reaction is the reverse of a synthesis reaction—a larger reactant is chemically broken down into two or more smaller products. T...

BIOLOGICAL MACROMOLECULES

Image
Bio-molecules are a subset of organic molecules. Organic molecules are defined as molecules or compounds that contain both carbon and hydrogen. Most organic molecules are a component of living organisms or have been produced from them. All other types of molecules are inorganic molecules including water, salts (e.g., sodium chloride), acids (e.g., carbonic acid), and bases (e.g., sodium hydroxide). The four major classes of organic biological macro-molecules (bio-molecules) are lipids, carbohydrates, nucleic acids, and proteins.
