Biological Role of Carbohydrates

1. Contribute to the Biosphere

The process of photosynthesis provides food for nearly all life on earth, either directly or indirectly. Organisms autotrophs (can change inorganic substances into organic), such as green plants, bacteria and algae utilize direct result of photosynthesis.

While the majority of heterotrophic organisms (which require organic compounds), including humans, is really very dependent on autotrophs organisms for food.

2. For Fuel and Nutrition

Carbohydrates provide the necessary basic needs of living bodies. For example, glucose (from carbohydrate compounds) which is the main nutrient cells. The body’s cells to absorb glucose and retrieve the stored energy to run the body’s cells. For humans, carbohydrates are a source of nutrients. In one gram of carbohydrates, there is an energy value equal to 4 calories.

3. As an Energy Reserves

Several types of polysaccharides serve as energy reserves. Later in the hydrolysis of reserve energy will for providing sugar to the cells when needed. Starch is a polysaccharide deposits in plants. Plants accumulate starch as granules or granules in the plastid organelles, including chloroplasts.

By synthesizing starch, herbs can pile up excess glucose. Glucose is the main fuel cell, so that the starch is stored energy.

4. As a matter Builders

Organisms building materials stronger than structural polysaccharides. For example, cellulose is a major component of the cell walls of plant cells. Cellulose is like fibers, clay, insoluble in water, and is found mainly in the stalk, stem, branches, and all the woody parts of the plant tissue. Wood is mainly made of other polysaccharides cellulose. For example, hemicellulose, and pectin. Meanwhile, the cotton is made almost entirely of cellulose.

5. As the Regulatory Fat Metabolism

Carbohydrates prevent the oxidation of fats that are not perfect. If enough energy is not available, will result in increased catabolism of fat. As a result, the accumulation of ketone bodies in the blood and occurs acidity.

6. As a saver Protein

Energy is the body’s primary needs. Therefore, if the carbohydrates that come from eating insufficient protein will be modified to produce a certain amount of energy. Though the protein has a primary function as a builder substance of tissue repair. In order to be used according to its function, carbohydrate must be met in the daily menu.
