According to the Osborne classification system, plant proteins are categorized into four main types based on their solubility. These diverse proteins, found in everything from seeds to leaves, play vital roles in plant growth and also serve as a crucial source of nutrition for humans and animals. So, what are the proteins obtained from plants called, and how are they further classified?

The enzyme RuBisCO is arguably the most abundant protein on Earth, making up a significant portion of the soluble protein found within plant leaves. This fundamental component leads to the question: Are leaves a good source of protein for human consumption? The answer is more complex than a simple yes or no.

Approximately 80% of the crude protein in fresh grass is 'true protein,' composed of amino acids that animals can effectively use. Understanding what kind of protein is in grass is critical for maximizing its nutritional value for livestock and exploring its potential for human consumption.

The most abundant protein on Earth is RuBisCO, a crucial enzyme for photosynthesis, while the most abundant protein in the human body is collagen, making up 30% of total protein content. This distinction is key to understanding which protein is found in the maximum amount, depending on the context.

While humans cannot digest raw grass like ruminant animals do, groundbreaking food science now allows us to safely extract and consume its protein content. This innovative process overcomes our biological limitations, transforming an otherwise indigestible resource into a viable and highly nutritious ingredient.

RuBisCO, a key enzyme responsible for photosynthesis in plants, is estimated to constitute over 50% of the soluble protein in plant leaves, making it the most abundant protein on Earth. This remarkable protein, often overlooked in the average nutrition diet, holds significant potential as a sustainable and nutritionally complete food source for a growing global population.
