A quality protein, for instance, contains all the essential amino acids in the proportions you need them. Milk protein, casein, is the highest quality protein. Egg protein, albumen, is next best. (Albumen is not albumin, a class of proteins found in your blood and other body tissues.) Your body can turn almost anything into its primary fuel, glucose, but it cannot turn fuel into the other nutrients it needs. Food quality is therefore determined by the essential nutrients present in that particular food.

The process of protein modification and shuttling between organelles is primarily facilitated by molecular machinery known as the endoplasmic reticulum (ER) and Golgi apparatus. The ER modifies proteins through processes like glycosylation, folding, and quality control. After modification, the proteins are then transported in vesicles from the ER to the Golgi apparatus. The Golgi further modifies the proteins and packages them into vesicles for transport to their final destinations within or outside the cell.
Protein quality, from a nutrition perspective, is a term used to describe how well a protein from food matches the body's requirements and, therefore, how useful the protein is for our body. This is determined by looking at the building blocks which make up the protein; called Amino Acids.There are 20 primary amino acids, 9 of which our body cannot make on its own. These are considered "essential" and so must come from our diet. A protein's quality is determined by asking the following questions:# Are all the 9 essential amino acids present in the protein?# Are the ratios of essential amino acids in the protein ideal?The first question is answered fairly easily with a "yes". In fact, pretty much every source of protein has at least someof all the essential amino acids. However, if the protein is deficient in 1 or more essential amino acid then it is considered incomplete. For your reference, grains are typically low in the amino acid lysine, while legumes are low in methionine. Animal products, on the other hand, are high in all the essential amino acids and are usually considered complete. (the exception being gelatin)Answering the second question is a bit more complex. Basically, the body needs a certain proportion of essential amino acids in the protein in order for it to be used most effectively. If all 9 are present yet 1 or more are not very abundant then the protein is of lower quality because the body will not be able to use the protein to its fullest potential.The "gold standard" used when determining protein quality is the egg (typically chicken egg). Eggs have all 9 essential amino acids in its protein and the ratios of these amino acids are very similar to the ideal protein needed by the body. You simply can't find better protein in your diet than egg protein! As a result, egg protein is considered the #1 quality protein and all other proteins from all other food sources are compared against this standard.http://www.faqs.org/nutrition/Pre-Sma/Protein.htmlhttp://en.wikipedia.org/wiki/Essential_amino_acids
The National Oceanic and Atmospheric Administration or NOAA, measures everything from air quality over the world's oceans to oceanic storms.
two factors influence protein quality- the proteins digestibility and its amino acid composition.

It has the highest protein efficiency ratio or best quality of protein of any food.
Yes there is protein in peas. In one cup of cooked peas, there is approximately 16.35g of protein.
True
Amino acids are the building blocks of protein?
Beans combined with a wheat product provide a whole protein source. Tofu, from soy, is also a good source.
The average avocado has about 3 grams of protein in it.
No-False Eggs are exceptionally high-quality protein. In fact, the only source of protein higher in quality than eggs is a mother's breast milk. Amino acids are the building blocks for proteins in our body, and eggs contain all nine of the essential amino acids-the ones our bodies cannot produce.
Slim-Fast is a well-known quality diet bar. Another quality diet bar would be the Special K Protein Bar. It has enough proteins to settle down the hunger of one's stomach.
Pregnant woman needs good supply of good quality proteins. The baby and placenta need proteins to grow. There is net 10 KG weight gain in pregnancy.
