Macronutrients of our body and it´s function

Macronutrientes clasificados y su importancia en nuestro cuerpo.

1. Macronutrients: Proteins

2. Macronutrients: Proteins Proteins perform vital functions such as building and repairing tissues (muscles, skin, bones), producing enzymes and hormones, transporting substances (such as oxygen), defending the body through antibodies, and regulating appetite and satiety. They are macromolecules that are essential for almost all cellular, structural, and metabolic functions in the body.

5. Macronutrients: Lipids

6. Macronutrients: Lipids Lipids are a diverse group of fatty, water-insoluble organic compounds, commonly known as fats, that perform vital functions in living organisms, such as long-term energy storage, cell membrane formation (phospholipids), thermal insulation, organ protection, and acting as chemical messengers (hormones). Examples of lipids include fats, oils, waxes, steroids (such as cholesterol), and phospholipids.

9. Macronutrients: Carbohidrates

10. Macronutrients: Carbohidrates Carbohydrates are one of the three main macronutrients, along with proteins and fats, that provide the body with the energy it needs for vital functions, being broken down into glucose (blood sugar). They are classified as sugars (simple) and starches (complex), and also include fibre, an indigestible part of food.

11. Macronutrients: Carbohidrates A healthy diet prioritises complex carbohydrates from whole grains, legumes, vegetables and fruit, rather than added sugars and refined grains, which provide few vitamins, minerals and fibre.

12. The main carbohidrates in our food:

13. Lab experiment: Nutrient testing

14. Carbohydrate testing: 1) Place Lugol's solution in the test tube and observe its reaction with the food (the presence of carbohydrate macromolecules is indicated by a purple coloration ). 2) Note which foods have undergone a change and which have not. In this way, we can check for their presence in the foods we consume.

15. Carbohydrate testing 2: 1) Place Benedict's reagent in the test tube and observe its reaction with the foods (the presence of carbohydrate macromolecules is indicated by a red or green coloration). 2) Note which foods have undergone a change and which have not. In this way, we can verify their presence in the foods we consume.

16. Protein testing: 1) Place acetone or hydrochloric acid in a test tube and observe its reaction with the food (the presence of protein macromolecules is indicated by a white coloration or cloudiness of the solvent ). 2) Note which foods have undergone a change and which have not. In this way, we can verify their presence in the foods we consume.
