The most limiting amino acid in cereal grain proteins (wheat, rice, corn) is lysine. The limiting amino acid in legume protein (peas and beans) is methionine.
First Class protein or complete proteins are those which have all the essential amino acids. They are usually animal proteins, though soya beans are also complete.

Confused understanding is obvious in the question.......... Proteins are long chains of amino-acids. There are 20 different ones required by humans but 12 of those can be made inside your body. The other 8 must be eaten in sufficient quantity and are known as essential amino-acids. Protein is lean meat - muscle fibre. With no essential amino-acids in your diet, or too little, you can make little or no muscle. The best and most available sources for the essential amino-acids, in adequate amounts, are animal muscle (meat, fish etc.), eggs, and pulses - peas and beans.
Incomplete proteins include Almond (nuts), grain and beans.
This protein is called a completeprotein.Protein is made from amino acids. Humans can synthesize most of the amino acids that we need to make protein, with the exception of nine essential amino acids (histadine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine) that must come from the foods we eat.In 1914, Thomas B. Osborne and Lafayette B. Mendel conducted studies which suggested that rats grew best when fed a combination of plant foods whose amino acid patterns resembled that of animal tissue. The term "complete protein" was coined to describe a protein in which all 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 disproven. 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.Whenever you eat, your body stores amino acids, and then withdraws them when it needs them to make protein. It is not necessary to eat any particular food or any particular combination of foods together at one sitting, to make complete protein. Your body puts together amino acids from food to make protein throughout the day.

provide proteins with essential amino acids
No. Almost all vegetarian foods have a variety of amino acids.

The ones that you have to eat are called essential amino acids and you can only get them in rich protein foods like meat or beans. Even many nuts are high in proteins.
First Class protein or complete proteins are those which have all the essential amino acids. They are usually animal proteins, though soya beans are also complete.

yes I'm positive..cheaters;)
Do you mean Amino Acid? Amino Acids are proteins, and the body cannot produce them itself. There are Complete Proteins which have all 27 of the essential Amino Acids in them. Examples would be meat, fish, eggs, dairy products. Then there are Incomplete Proteins which have some, but not all, of the 27 essential amino acids, and they are vegetable in origin and examples include beans and nuts.
Beans lack some of the essential amino acids to make it a complete protein. You can get those amino acids from grains or seeds. This is why combinations like beans and rice, peanut butter on toast, and refried beans with corn bread are common. Of course, the easiest way to get a complete protein is to eat meat.
Some food sources of the eight essential amino acids are eggs, soy protein, lentils, dairy, sesame, peas, and fava beans. The eight essential amino acids are isoleucine, valine, phenylalanine, tryptophan, leucine, threonine, methionine, and lysine.
