Want this question answered?
how does one protein differ from another protein?
amino acid molecules are water soluble meaning they cannot enter the cell. Fatty acid molecules CAN enter the cell.
Amino acids differ according to their R groups. All amino acids have an amino group, a carboxyl group (organic acid), and a hydrogen atom attached to a central carbon atom. Also attached to the central carbon atom is an R group that varies according to the amino acid. Refer to the related links for illustrations.
Assuming that you are talking about the amino acids that are synthesized from tRNA, the difference between one amino acid and another is the 3 letter RNA sequence that calls for the acid: UUG would call for one acid, while AAC will most likely call for another.
Proteins differ each other in their amino acid composition and the number of amino acids that form it. Not all the proteins are the same, although they are all made up of amino acids. the sequence of amino acids is determined by the mRNA which is transcribed by DNA in the nucleus.

It depends on the role of the amino acid that is altered. One amino acid might be replaced with no measurable effect on the protein's function; replacing another might cause a total loss of function.

No, amino acids are proteine molecules.
