One fact that you may heard over and over is that our body is made of water , however , did you know that 17% of our body is made up of protein? Well i'm here to talk and show you the amazing structures and functions of proteins!

What is Protein? A protein is a basic structure found in all life, composed of 20 amino acids , which are smaller molecules containing carbon , oxygen , hydrogen , and sometimes sulfur atoms. these individual amino acids can be combined in various ways . 

 

From where do the amino acids come from? amino acids are essential for our body's function, derived from food and made in the body. They are broken down into individual amino acids, which are then transported to cells for cell assembly. Our bodies can produce half of the amino acids needed, while the rest come from food.

why do do we need to eat proteins?Protein is an important part of a balanced diet. Proteins are made up of chemical 'building blocks' called amino acids. The body uses amino acids for hormone production, enzyme synthesis, and the maintenance and repair of muscles and bones. They can also be used to generate energy. They are also an important part of the food group.

What do Proteins do in our body? Around 20,000 proteins exist in our body, carrying out various functions such as metabolic conversions, cell assembly, and muscle function. These proteins are categorized into structural functions like collagen, integrin, and keratin, which form the body's structures. They also play a significant role in biochemistry, such as breaking down fat or amino acids, and carries oxygen in the blood. Additionally, proteins can process signals and information, such as circadian clock proteins, which maintain time in cells.

                    

How much protein do we need in a day : Protein requirements vary according to weight and activity level. The average adult requires 0.8 grams of protein per kilogram of body weight per day, while athletes require between 1.2 and 2.0 grams, with endurance athletes needing the least and strength and power athletes needing the most. Athletes need to consume 1.2 to 2.0 grams of protein per kilogram of body weight each day, depending on their degree of activity.

Lab report 

Station 2: protein test 

Based on the provided procedure and purpose of Station 2, the aim is to determine which food among egg white solution (gelatin solution), milk, soda (7Up), and water contains the most protein. The Biuret solution is used to test for the presence of protein, and a color change to dark violet indicates the presence of protein.

Procedure/Observation:

1. Label the test tubes as 1, 2, 3, and 4.
2. Pour 5 ml of Biuret solution into each test tube.
3. Add 10 drops of egg white solution to test tube 1.
   Add 10 drops of milk to test tube 2.
   Add 10 drops of soda to test tube 3.
   Add 10 drops of water to test tube 4.
4. Gently shake each test tube until you see a color change.
5. Record your observations.

Concluding the experiment:

Observing the dark violet color change in the test tubes indicates the presence of protein ,the food that is likely to have the most protein could be the egg white solution (gelatin solution). Egg whites are known to be a good source of protein, so it is possible that the test tube containing the egg white solution would exhibit a stronger dark violet color change compared to the other test tubes.
