Question

Name the most abundant protein in the animal world.

Answer 1

Hint: Protein is a substance that has amino acids and some compounds such as carbon, hydrogen, oxygen, nitrogen and sulfur and is found in many foods.
They are one of the elementary units of body tissue and can also serve as a fuel source.

Complete answer:
Protein:
- It provides us energy because it serves as a fuel source.
- They are polymer chains made of amino acids that are linked together by peptide bonds.
- Proteins are large molecules that our cells need to function properly.
- They consist of amino acids.
- The animal body depends upon the proteins for their structure and for performing various functions.
- Protein has many roles in your body.
- It provides us energy because protein acts as a fuel source in our body.
- It also maintains the proper ph and fluid balance.
- The most abundant protein present in the animal world is collagen.

Collagen:
- It is a protein made from amino acids, specifically glycine, proline, hydroxyproline, and arginine.
- Collagen peptide supplements are derived from bovine connective tissue or fish.
- It accounts for around 30% of the total protein content of the human body.
- It provides strength, integrity, and structural support.

Hence, The most abundant protein is Collagen.

Additional information:
- During human digestion, proteins are broken down in the stomach to smaller polypeptide chains via HCl and protease actions.
- There are basically nine essential amino acids which humans must obtain from their diet in order to prevent protein energy malnutrition and resulting death.
- They are phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine and histidine.

Hydrolysis: It means chemical breakdown of substance due to the presence of water.
- When digestive proteolytic enzymes act upon the protein in the gut the peptide bonds get hydrolyzed and a mixture of amino acids is obtained.

Note: In plants, the most abundant protein is Rubisco.
Rubisco: It is an enzyme involved in the first major step of carbon fixation.
Carbon fixation is a process by which the atmospheric carbon dioxide is converted to energy rich molecules such as glucose.
It catalyzes the carboxylation of ribose 1, 5- bisphosphate also known as RuBP.
It is probably the most abundant enzyme on Earth.
