A few words about significant and unique illustrations. Table (and its derivative Tables from 2.1 to 2.5) presents the perfect amino acid system-arrangement (PPAASS), ordered by chemical similarity of individual molecules, while in Table .6, a systemarrangement, according to the similarity of molecular classes, arranged: in the penultimate row are AAs, which contain only carbon and hydrogen in the side sequence; in the last row are those AAs that, in addition to carbon and hydrogen, also contain nitrogen; in the first row are AAs, which, in addition to carbon and hydrogen, also contain oxygen; finally, in the second row are "combined" AAs: glycine, which contains only hydrogen in the side chain; along with it are two amides, which have nitrogen and oxygen added to the hydrocarbon base; finally, there are the only two sulfur AAs, cysteine and methionine.
