Giving new meaning to the expression, “going at a snail’s pace”! For instance, they lay eggs, and do not like to eat rotting plants or algae. They went from looking at a basket of miscellaneous items and going, “WHAT?? Because the amino acid sequence ultimately dictates the three-dimensional shape of the resulting peptide, different sequences of amino acids form peptides with different shapes. My favorite part was watching them build the models. Antentome helena is the scientific name. What 3D peptide conformations can you make in this way? Next, look at the column labeled “Cysteine Framework”–this column gives a best-guess for which cysteines form disulfide bridges together. Unlike bettas, who can tolerate nitrates up to 40 ppm, most snails, and other invertebrates, can only tolerate 20 ppm or less of nitrates. The snail’s own genetic code determines the order of amino acids in a conotoxin, which influence the ultimate 3D structure of the conotoxin peptide.
