Amino acids are relatively small molecules with molecular weights around 100-200. (PP 10) They are used to produce energy, to synthesize other molecules like hormones, and to make proteins. Proteins are polymers of amino acids. (PP 11) They fold into specific shapes and range in molecular weight from several thousand to over a million.

or ink is formed by pigment molecules present in flowers, trees, and animals. The color is made by absorbing, or subtracting, certain parts of the spectrum and reflecting or transmitting the parts that remain. Each pigment molecule seems to have its own distinct characteristic way of reflecting, absorbing, or transmitting certain wavelengths.
