  • Lipid contents and fatty acid compositions of 16 kind sea algaes in the southern sea coast of Korea were analyzed to evaluate nutrient significance of total polyene, n-3 polyenes and n-6 polyene fatty acids. Total lipid contents were 0.58 ∼ 3.00% in 9 kinds of brown algaes, 0.47 ∼ 2.16% in 5 kinds of red algaes and 0.55 ∼2..99% in 2 kinds of green algeas. N-3 polyenes and n-6 polyenes of the fatty acid compositions were 1.46∼25.67% and 0∼48.51% in the brown algaes, 1.17∼21.91% and 0.28 ∼29.35% in the red algaes, and 3.67%∼ 10.61% and 4.10 ∼ 8.66% in the green algaes, respectirely. The fatty acid contents and compositions of n-3 polyenes and n-6 polyenes, monoenes and saturates were vary different in the algae groups and sepecies.

  • A novel topological index (TG Index) has been introduced. The graphical matrix representation of the TG index includes the use of directed subgraphs for the first time in graph theory literature. The application of the TG index on certain properties of polyenes yielded very well correlation data.

  • Total lipid contents were 0.58∼3.00% in 9 kinds of brown algaes, 0.47∼2.16% in 5 kinds of red algaes and 0.55∼2.99% in 2 kind of green algeas, respectively. Fatty acid compositions of the algaes were determined by gas liquid chromatography. Total polyenes and n-3 polyenes of linoleic acid(18:3), stearidonic acid(18:4), eicosapentaenoic acid(20:5) and docosahexaenoic acid(22:6) were 3.88∼57.57% and 1.46∼25.67% in the brown algaes, 5.30∼39.75% and 1.17∼21.91% in the red algaes, and 7.76∼19.27% and 3.67%∼10.61% in the green algaes, respectirely. The fatty acid contents and compositions of total polyenes and n-3 polyenes were vary different in the algae groups and sepecies.

  • Fatty acid composition of frond, spororphyll and stipe of Miyeok (Undaria pinnatifida) were extensively analyzed to evaluate a nutrient significance of n-3 polyenes, n-6 polyenes, ${\gamma}$-linolenic acid (18:3, n-6) and $\alpha$-linolenic acid (18:3, n-3). Polyenes of $\alpha$-linolenic acid (22:6, n-3), stearidonic acid (18:4, n-3), eicosapentaenoic acid (20:5, n-3) and docosahexaenoic acid (22:6, n-3) were as high as 29.69%, but ${\gamma}$-linolenic acid (18:3, n-6) was as low as 0.90% when compared to total polyenes of 44.18% in frond. The n-3 polyenes of neutural lipids, glycolipids and phospholipids were 22.40%, 35.82% and 3.53% in frond, 5.26%, 9.51% and 2.37% in stipe and 8.01%, 4.49% and 2.14% in sporophyll, respectively. These results suggest that total polyenes and n-3 polyenes in frond of Miyeok may be used as resource of functional food.

  • The present study was carried out to compare the difference of proximate composition and lipid peroxides in juvenile(80~120g) and adult(670~690g) rainbow trout(Oncorhynchus mykiss). There was a marked increase in lipid content with growth. The fatty acids of juvenile rainbow trout was composed of saturates, monoenes and polyenes of 30.18%, 37.81% and 25.09%, respectively. Adult rainbowtrout showed higher content in monoenes and lower content in polyenes. The composition of amino acid was similar. In both groups, glutamic acid, aspaitic acid, histidine were abundant. The lipid peroxides, malondialdehydes and lipofuscin, were not increased significantly with growth.

  • The HOMO-LUMO gap, and static and dynamic third-order polarizabilities for the polyenes are evaluated by means of the time-dependent Hartree Fock(TDHF) semiempirical PM3, AM1, MNDO, and MINDO/3 calculations. All calculations have performed on the series $C_2H_4$ to $C_{32}H_{34}$. The HOMO-LUMO gap increases in the order: MINDO/3> MNDO> PM3> AM1 levels. THG, DC-EFISHG, IDRI, and OKE for the various calculations show the order: AM1 > MNDO > PM3 levels. The various third-order effects for the polyenes have the following order: THG> DC-EFISHG> IDRI> OKE.

  • $\pi$-Binding energy of the 153 kinds of unsaturated acyclic polyenes and unsaturated cyclic polyenes has been calculated by the Kier's Molecular Connectivity Index. An excellent linear correlation is found between HMO $\pi$-binding energy and $\pi$-binding energy calculated by the Kier's Molecular Connectivity Index. In either class of unsaturated acyclic hydrocarbons and unsaturated cyclic hydrocarbon, the regression analysis reveals a highly significant linear correlation between $E_{\pi}$ and $^1{\chi}^v$ (the first order valence connectivity index).
