pol·y·am·ine

(pol'ē-am'ēn), Although this word is correctly stressed on the second-last syllable, U.S. usage often stresses it on the last syllable.
Class name for substances of the general formula H2N(CH2)nNH2, H2N(CH2)nNH(CH2)nNH2, H2N(CH2)nNH(CH2)nNH(CH2)nNH2, where n = 3, 4, or 5. Many polyamines arise by bacterial action on protein; many are normally occurring body constituents of wide distribution or are essential growth factors for microorganisms.
[G. polys, much, many + amine]

polyamine

/poly·am·ine/ (-am´ēn) any compound, e.g., spermine or spermidine, containing two or more amino groups.

polyamine

(pŏl′ē-ə-mēn′, -ăm′ēn)
n.
Any of a group of organic compounds, such as spermine and spermidine, composed of only carbon, nitrogen, and hydrogen and containing two or more amino groups.

polyamine

[pol′ē·am′ēn]
any compound that contains two or more amine groups, such as spermidine, spermine, and putrescine that are normally found in human tissue. Many polyamines function as essential growth factors in microorganisms such as in DNA synthesis and gene expression.
