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.

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.

They contain all the essential amino acids needed for a healthy diet, unlike plants which contain only a few of the essential amino acids.

What the different of first class and second class of protein?

The difference between first class and second class proteins lies in their amino acid profile. First class proteins, also known as complete proteins, contain all essential amino acids in sufficient quantities for human needs. Examples include animal proteins like meat, fish, eggs, and dairy. Second-class proteins, known as incomplete proteins, lack one or more essential amino acids. These are typically plant-based proteins like legumes, grains, nuts, and seeds.
