each amino acid has the fundamental structure, differing only in the side chain, designated the R - group
It helps with growth and repair of the body
The R group in an amino acid are what make that amino acid unique.
The protein food group is most important for building cell structures.
the optimal pH distrups the normal instructions of the R group within the protein molecule
Thiols.
Because each amino acid put into the growing polypeptide chain that will become a protein has an R group with different binding characteristics that can change the shape of the protein, thus the action of the protein, if not accurately placed for that particular protein in it's tertiary form.
All amino acids contain a central carbon atom to which are attached a carboxyl group (O-C=O), an amino group (H-N-H), a hydrogen atom and a variant R-group.Each amino acid has a different R-group. For instance, the simplest amino acid, glycine, has an R-group consisting of one hydrogen atom.Diagram in [related links]
The 20 amino acids vary in structure by the R-group, otherwise all amino acids are the same in structure. All amino acids have a carboxyl group, an amino group, an R-group, and a hydrogen which are all bonded to a central carbon. It is the R-groups that make the amino acids react in different ways and alter the structure of the protein.
