They're not.
In 1914, Thomas B. Osborne and Lafayette B. Mendel conducted studies on rats, which suggested that they grew best when fed a combination of plant foods whose amino acid patterns resembled that of animal protein. That makes sense, as all baby mammals, rats and humans included, grow best when fed the perfect food for baby mammals: their mother's milk. The term "complete protein" was coined to describe a protein in which all eight or nine essential amino acids are present in the same proportion that they occur in animals. "Incomplete protein" described the varying amino acid patterns in plants. It's a misleading term, because it suggest that humans (and other animals, one would assume) can't get enough essential amino acids to make protein from plants.
Fortunately, the theory that plant proteins are somehow "incomplete" and therefore inadequate has been disproved. All unrefined foods have varying amounts of protein with varying amino acid profiles, including leafy green vegetables, tubers, grains, legumes, and nuts. All the essential and nonessential amino acids are present in any single one of these foods in amounts that meet or exceed your needs, even if you are an endurance athlete or body builder.
What else can I help you with?
Why are animal proteins better to eat than plant proteins?
More amino acids.
Are proteins of one plant are like proteins of other plants but animal proteins are unlike each other and plant proteins?
Proteins from different plants can share similar structures and functions due to common evolutionary ancestry and environmental adaptations, leading to some similarities in their amino acid profiles. However, plant proteins often differ from animal proteins in their amino acid composition and digestibility. Animal proteins typically contain a more complete set of essential amino acids and are usually more bioavailable for human consumption. Thus, while there are similarities among plant proteins, they are generally distinct from animal proteins.
Which of the following nutrient sources yields more than 4 kcalories per gram. Answer a Plant proteins b Plant fats c Animal proteins d Plant carbohydrates?
b Plant fats and c Animal proteins yield more than 4 kcalories per gram, with fats supplying 9 kcal/g and proteins providing 4 kcal/g. Plant carbohydrates and proteins usually provide 4 kcal/g or less.
Why are animal foods more expensive than plant foods?
because things that are delicious cost more
Are there more animal cells or plant cells?
That depends on the animal or plant in question.
Why animal cells have more ribosomes than plant cell?
Much more need for proteins in animal cells. Much of plant building material is forms of glucose made by photosynthesis, so not the great need for the " workbench " on which proteins are synthesized; the ribosomes.
Which is more expensive fuel or uranium?
Uranium is more expensive, but the kWh in a nuclear power plant is more cheaper.
What is the tadpole more like a plant or animal?
its an animal
What has more structures a plant or animal cell?
Plant
Which cell is more rigid plant or animal?
plant.
Is Golgi bodies in plant or animal cells?
Golgi bodies are found in both plant and animal cells. There may in fact be more Golgi bodies per cell in plant cells than in animal cells. Golgi Apparatus is found in both animal and plant cells. It is known as dictyosomes in plant cells and Golgi complex in animal cells. But the function remains the same.
Why are animals first class protein?
Animal proteins are considered "first class" or "high quality" proteins because they contain all the essential amino acids required by the human body in the right proportions. This makes animal proteins more easily digestible and more readily absorbed compared to plant proteins. Additionally, animal proteins tend to have higher biological value, meaning they provide a more complete source of amino acids for human nutrition.
