The Importance of Water as a Medium for Life

Water is a very important liquid found on the surface of the earth, accounting for 60% to 90% of the fresh mass of whole organisms and is very important for cells. It is an important habitat for animals such as fish and other aquatic life. It consists of two hydrogen atoms and is covalently bonded to an oxygen atom. When discussing what makes water an important medium in life unless consideration is given to its properties such as its dipole charge, its ability to act as a solvent, its thermal properties, its density, its high surface tension and aggregation It will not.

Biological importance of water as solvent and biological media Water is the most important material life we ​​know because it is necessary for survival and it also provides the environment for many species . All cells contain at least 85% water and most of the liquid inside and outside the cell can contain at least 90% water. Molecular transport and chemical reactions occur in dissolved water. Chemically, water molecules are strong dipoles, making water a highly effective solvent especially for crystalline salts. Therefore, water is the body's solvent, and it controls all functions.

Water is the most important substance in life on earth. It provides a medium for all metabolic processes. Therefore, it must absorb large amounts of nutrients, but it does not provide nutritional value on its own. Water usually contains nutrient micronutrients such as calcium and salt, but you can put other water in the tap water such as chlorine and fluorine for various purposes such as hygiene and dental hygiene. Almost every diet plan is based on the wise allocation of these three elements in the required ratio. For example, a 2000 calorie diet includes 800 calories (1 gram protein = 4 kcal) from 200 gram protein, 800 calories (200 grams carbohydrate = 1 kilogram carbohydrate = 4 kcal) from 200 grams carbohydrate, and 44 grams fat 400 calories (1 calorie) from gram fat = 9 kcal)
