Chymotrypsin, trypsin, and elastase are digestive enzymes called serine proteases. the serine proteases differ in substrate specificity: chymotrypsin cleaves peptide bonds after aromatic or bulky hydrophobic side chains; trypsin requires basic amino acid residues; and elastase cleaves bonds following small uncharged side chains. a chart of amino acids can be found here. the specificity pockets (substrate-binding sites) of each of the serine proteases are drawn below.

answer: were is your serine image

explanation:

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
