There are 20 amino acids which humans need to construct all the different proteins we need in our bodies. 12 of them are 'non-essential'; 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 non-essential ones too).They are also called complete proteins in the sense that they contain the 8 essential amino acids needed by humans, the ones that if missing from the diet can't be produced in the body by modifying the ones that are obtained in food staffs.
Animal proteins are complete, plant proteins are not but often different plant food staffs (e.g bread and beans) provide amino acids that between them complete the set of eight essential amino acids.First class proteins- isn't that just the same as primary proteins?
From what i know, primary proteins is shape of the 'normal' polpeptide chain. You might already know that the polypeptide chain is baisically;
amino acids joined to form a dipeptide (via condensation reaction - forms h20 molecule) These dipeptide join in excatly the same way as the were formed to produce polypeptide chains. These are held together by PEPTIDE BONDS. Hope this helpsA complete protein source is like an egg white, since it contains all the essential amino acids. See the link, too.meat proteinsegg white, milk and fish
basically the enzymes break down to make it called 1st class
Because animal proteins contain more or all(20) of the essential amino acids that we require for our good health than any other type of protein.
i dont knoww
They actually belong to the group called Mollusks.
A penguins class is Aves and their infraclass is Neognathae.
A good class pet would be a Guniea pig.
A stingray is a mollusk
Arachnids
animal proteins are called first class proteins.
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.

- Explain why the strategic management class is often called a " capstone course "
gamma globulins
Hydrolytic enzymes that break down proteins are a class of enzymes called proteases.
Antibodies belong to the class of macromolecules known as proteins. They are Y-shaped proteins produced by the immune system in response to the presence of foreign substances called antigens.
A hormone is an example of the globular class of proteins
what is the difference between first and second class proteins
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.
A substance that enhances a chemical reaction is a catalyst. Certain proteins that are catalysts are called enzymes. An example of an enzyme is pepsin.
