Nitrogen. It is the key element in protein building, because N2 fixation is a very expensive process made by cyanobacteria when H2 is combined to form NH2, then roots take it and send it to the leaves and there it is used to produce aminoacids, then they form oligopeptides, then proteins.

CHNO are absolutely critical elements, since they form the amino acids. N makes the difference to the other two main groups of biological matter, sugars (starch, cellulose) and fats.

Sulphur is required for cystein-containing proteins.

Since proteins are chains of aminoacids (there are about twenty different of them), all the elements you find in every aminoacid:
Carbon, hydrogen, oxygen, nitrogen. A couple of the aas also include sulphur.

Proteins are made of amino acids.
That means u can call the protein are amino acids.
but u cannot call all amino acids are proteins
becoz all amino acids never code for proteins.

Like Enzymes are kind of protein molecule.
But all proteins are not enzyme.

Amino acids are the main element to form protein.
