To answer this question we have to talk a process called: "Translation". After the "Transcription", that is, the mechanism from where a mRNA molecule is synthesized from a DNA double helix. The mRNA molecule migrates outside the nucleus to the cytoplasm and specifically to the ribosomes (a complex protein organelles that serve as building machines for new polypeptide molecules). The mRNA molecule carries the specific sequence for the synthesis of the new polypeptide (protein) chain and serves as a "template" for the proper order of the amino acids that will constitute the new protein molecule. To add the amino acids to the growing polypeptide chain are necessary the tRNA molecules (these RNA structures carry a single amino acid that will be added to the growing polypeptide chain). Each tRNA has a specific three-nucleotide sequence (called "anticodon") that recognizes the corresponding three-nucleotide sequence (codon) on the mRNA molecule. Each amino acid monomer (carried by its particular tRNA) is anchored, one by one, to the previous amino acid that was added before by a peptide bond. This mechanism is taken place in a particular region of the ribosome, a cleft that provides the nascent polypeptide's exit path.
We humans cannot make all the amino acids we need in order to build proteins.
We can make some of them (e.g. tyrosine) from others (tyrosine is made by an enzyme acting on another amino acid, phenylalanine).
But we cannot make the others (e.g. phenylalanine), and they are called essential amino acids, because we have to have them in our diet.
The number of essential amino acids depends on age(children need a few more than adults, who can synthesize them) and on our genetic make-up (some diseases involve an inability to make an amino acid, which therefore is added to the essential list for that person).

Amino acids
Amino acids are the only building blocks for protein.
They are the amino acids. They are the monomers
They are Protein Sub-Unit amino acids.
amino acids are the monomers for protein
Amino acids
A protein molecule is a long chain of amino acids. There are 22 different amino acids and their chemical properties determine the shape of the protein which determines the function of the protein.
Amino acids.
Melamine is a protein, which is made of amino acids.
because protein are formed from amino acids
The order of amino acids in a protein determines its structure and function.
amino acids make proteins and an enzyme is a protein so......
Amino acids are the building blocks of proteins; hence the intake of amino acids will act nutritionally as protein.
amino acids amino acids
Proteins are polymers of amino acids.
