There are 20 amino acids which humans need to construct all the different proteins we need in our bodies. 12 of them are 'nonessential; they can be made in the body by conversion from another molecule or amino acid. However 8 are 'essential'; they cannot be made in the body and so must be provided in the diet if deficiency diseases are to be avoided.
A first-class protein is one which contains all 8 essential amino acids (and may contain some of the nonessential ones too).

What are 'first class proteins'?
animal proteins are called first class proteins.
What the different of first class and second class of protein?
proteins from animal origin are called first class proteins. meat and fish are first class proteins because they contain all the essential amino acids (which cannot be made by the body), plant proteins are called second class proteins.
What is the differant between first class and second class?
proteins from animal origin are called first class proteins. meat and fish are first class proteins because they contain all the essential amino acids (which cannot be made by the body), plant proteins are called second class proteins.
What is the role of protein in building muscles?
Protein is consider the top supplement and the most important for muscle building. But if you're going to take protein, don't forget to eat well and don't think of protein as a "meal" but as a dessert.
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.
What are good sources of proteins?
Animal proteins are good source of first class proteins. First class proteins contains all the essential amine acids. Eggs top the list with 98 % bio-available. Then chicken and meat as well as fish are good sources of first class proteins. For vegans milk and milk products are good source of first class proteins. Pasteurized or boiled milk should be kept in freeze for 4 to 6 hours or overnight and fat should be removed before consuming the milk. Any amount can be taken freely after removing fat from milk. It is very good source of first class proteins. Others are cereals should be mixed with pulses. Proportion should be 4 to 2 parts of cereals with one part of pulse.
What are the Two kinds of Protein?
Not sure exactly what you mean, there are hundreds of different proteins, but in nutrition you have: first class proteins: proteins that contain the eight essential amino acids that cannot be produced in the human body and so must be eaten, they are usually found in meat. second class protein: proteins that are made up of non- essential amino acids, those that can be produced in the body.

What are the first class proteins?
Eggs and Sperm.
When is protein considered to be first class?
Always
Why is accurate initiation of protein synthesis important?
It is the first step in creating proteins.
