di-3: tri-4: tetra-5: penta-6: hexa-7: hepta-8: octa-9: nona-10: deca-The rules for using the prefix system of nomenclature of binary compounds can be summarized as follows: Generally, the less electronegative element is written first in the formula, though there are a few exceptions. Carbon is always first in a formula and hydrogen is after.

NT-1.3 - When alone, the number 1 is represented by "mono-" and 2 by "di-". In association with other numerical terms, the number 1 is represented by "hen-" and 2 by "do-". Examples: Compare monochloro with henicosane. Compare dichloro with dodecane NT-1.4 - As an exception to Rule NT-1.3, the number 11 is represented by undeca- instead of.

di: tri: tetra: penta: hexa: hepta: octa: nona: deca: The prefixes come from Greek. You will put the element that is more left on the periodic table first, unless it is oxygen, which is always last unless it is in a compound with fluorine. This follows the same pattern as ionic compounds. In ionic compounds, the cation is written first, and you.

Fungal cyclic peptides mainly include cyclic di-, tri-, tetra-, penta-, hexa-, hepta-, octa-, nona-, and decapeptides. Recent special reviews covering the chemical synthesis , biosynthesis [11,12], as well as developments and applications (i.e., echinocandins, pneumocandins and cyclosporin A) [13,14] of fungal cyclic peptides are available.
