Answer 3

dear friend,

I know of one thing and thats for sure that every human
needs proteins for healthy life along with vitamins minerals and little of carbohydrates and fats and water.
As for proteins it contains 22 amino acids required for our body.Out of which our body manufactures only 13 and 9 essential amino acids have to be consumed externally.
They are found in rich content in SOY protein concentrate ( Nutrilite Protein Powder).

have healthy life

Answer 4

There are several. These are the polymers of amino acids.
So change in the sequence in the aminoacids can change the property of the protein and hence its function.

Answer 5

A List of types of proteins is part of on-going attempts to manage the large amounts of information concerning genes and proteins. Gene sequencing efforts and genome sequencing projects have led to the creation of many gene databases and attempts to organize all of the available information. One such organization effort is known as Gene Ontology. Since geneticists are often concerned with a different set of problems than are the biologists who study protein structure and function, protein ontology, while related to gene ontology, is a distinct effort to name and categorize proteins.

The List of types of proteins (on this page, below) is based on the biological categories described in the GO Slims list for "GOA and whole proteome analysis" (format-version: 1.0 date: 17:08:2005 14:57). Modifications are being made as needed, but an effort is being make to keep these "top level" categories limited in number.
