What is Rubisco?

The full name of Rubisco is Ribulose-1,5-bisphosphate carboxylase-oxygenase. It is an enzyme found in every green leaf. It plays an important role in the life and development of plants. Its short name RuBisCO is formed from the initial letters of this long name.

What does Rubisco do in plants?

Rubisco is considered to be the most abundant enzyme present on earth. It helps in converting carbon dioxide into energy-rich substances like glucose in the process of photosynthesis. In simple words, it helps plants make food and produce the sugars needed for their growth.

Is it beneficial for humans also?

According to experts, Rubisco can become a great plant-based protein of the future. It contains all the 9 essential amino acids required for the body. This is why it is considered a high quality protein.

Why is it special for fitness and muscles?

Rubisco is easily digested and breaks down rapidly in the stomach to provide amino acids. This may help in muscle recovery and repair. Apart from this, some beneficial peptides are also released during digestion, which can provide additional benefits for health.

No allergy problem either

Another specialty of Rubisco is that it generally does not cause allergies. It does not contain common allergens like dairy, soy or gluten. Additionally, its taste is mild and texture is versatile, due to which it can be included in many types of food products. Since it is not allergic, everyone can consume it.

Then why haven't you become famous yet?

Although Rubisco is the main protein in leaves, it accounts for only about 3 percent of the total leaf. The process of removing it is quite tough and expensive. For this the cell wall and chloroplast membrane of plants have to be broken. Also, processing has to be done within a few hours of cutting the leaves, which makes production even more difficult.
