There are a total of 16 possible dipeptides that can be formed from combining the four amino acids (4 amino acids * 4 amino acids = 16 dipeptides).

peptides which are constructed from amino-acids
Amino acids are called amino acids because they contain an amino group (-NH2) and a carboxyl group (-COOH) in their chemical structure. These two functional groups are essential for the formation of proteins and are characteristic of all amino acids.

There are 22 "standard" amino acids, although many others exist
There are 20 naturally occurring amino acids found in living things.

amino acids?? 20 amino acids
There are 22 amino acids that humans require for life. however, there are hundreds of different kinds of amino acids.
Amino acids... Like this Protien>amino acids>RNA nucleotides The amazing thing is that only 20 different amino acids exist in the human body yet mix/match/repeat to make all of the protiens in the body!

Fructose is a saccharide, and is not constructed of amino acids
100 amino acids long
A pentapeptide contains five (penta-) amino acids.
Amino acids held together by peptide bonds.
