  • The degradation of l-threose at Maillard reaction conditions
    作者:Elaine Yinan Li、Milton S. Feather
    DOI:10.1016/0008-6215(94)84225-6
    日期:1994.3
    L-Threose, a comparatively unstable aldose, is produced from L-ascorbic acid in the presence of oxygen and participates vigorously in Maillard reactions, even at comparatively mild conditions. In the present study, the degradation of L-threose at pH 7.0 alone, in the presence of N-alpha-acetyl-L-lysine, and at pH 2.0 alone at 37 degrees C was investigated by identification of some of the products produced
    L-苏糖,一种相对不稳定的醛糖,是在氧气存在下由L-抗坏血酸产生的,即使在相对温和的条件下,也能强烈参与美拉德反应。在本研究中,通过鉴定一些在乙醇中产生的产物,研究了仅在pH 7.0时,在N-α-乙酰基-L-赖氨酸存在下,以及仅pH 2.0时在37℃下L-苏糖的降解情况。通过GLC和GLC-MS进行反应。在鉴定出的化合物中,有3-脱氧-四-2-戊糖(1),预测的碱重排产物,其衍生自1(2,4-二羟基丁酸酯,4-碳间糖酸)以及甘油醛。同位素示踪剂研究清楚地表明,甘油醛是由起始L-苏糖分子中C-1的丢失而产生的。

  • Identification and Determination of α-Dicarbonyl Compounds Formed in the Degradation of Sugars
    作者:Teruyuki USUI、Satoshi YANAGISAWA、Mio OHGUCHI、Miku YOSHINO、Risa KAWABATA、Junko KISHIMOTO、Yumi ARAI、Kaoru AIDA、Hirohito WATANABE、Fumitaka HAYASE

    The α-dicarbonyl compounds formed in the degradation of glucose and fructose were analyzed by HPLC using 2,3-diaminonaphthalene as derivatizing reagent, and identified as glucosone (GLUCO), 3-deoxyglucosone (3DG), 3-deoxyxylosone (3DX), tetrosone (TSO), triosone (TRIO), 3-deoxytetrosone (3DT), glyoxal (GO), and methylglyoxal (MGO). The results suggest that α-dicarbonyl compounds were formed from glucose via non-oxidative 3-deoxyglucosone formation and oxidative glucosone formation in glucose degradation. In addition, TRIO, GO, and MGO were also formed from glyceraldehyde as intermediate. The α-dicarbonyl compounds might be formed from glucose via these pathways in diabetes.
    在葡萄糖和果糖降解过程中形成的α-二羰基化合物通过高效液相色谱(HPLC)使用2,3-二氨基萘作为衍生试剂进行分析,识别为葡萄糖苷(GLUCO)、3-脱氧葡萄糖苷(3DG)、3-脱氧木糖苷(3DX)、四碳糖苷(TSO)、三碳糖苷(TRIO)、3-脱氧四碳糖苷(3DT)、乙二醛(GO)和甲乙二醛(MGO)。结果表明,在葡萄糖降解过程中,α-二羰基化合物是通过非氧化的3-脱氧葡萄糖苷形成和氧化的葡萄糖苷形成而产生的。此外,TRIO、GO和MGO也作为中间体从甘油醛中形成。这些α-二羰基化合物可能通过这些途径在糖尿病中由葡萄糖形成。
  • Reactivity of 1-Deoxy-<scp>d</scp>-<i>erythro</i>-hexo-2,3-diulose: A Key Intermediate in the Maillard Chemistry of Hexoses
    作者:Michael Voigt、Marcus A. Glomb
    DOI:10.1021/jf900459x
    日期:2009.6.10
    Among the compounds identified were carboxylic acids (glyceric acid and acetic acid) that can be seen as stable Maillard end-products. However, the formation of dicarbonyls (3,4-dihydroxy-2-oxobutanal, 1-hydroxybutane-2,3-dione, and 4-hydroxy-2-oxobutanal) and of hydroxycarbonyls (acetol) was verified presenting unstable, reactive Maillard intermediates. Results confirmed that β-dicarbonyl cleavage
    在1-丙氨酸存在下,在中等条件下(37和50°C)研究了1-脱氧己基-2,3-二糖(美拉德化学中的关键中间体)的降解。完成了各种分析策略,以涵盖所形成产物的广泛范围及其不同的化学性质。这些涉及GC-MS分析三甲基甲硅烷和ö -benzyloxime三甲基甲硅烷衍生物(与反应后ö -benzylhydroxylamine和Ñ,ö,GC-FID(后乙酸癸基酯的分析用氯甲酸癸基反应-双(三甲基硅烷基)乙酰胺) )和喹喔啉衍生物的HPLC-UV分析(与邻苯二酚反应后-苯二胺)。在鉴定出的化合物中,有羧酸(甘油酸和乙酸),可以认为是稳定的美拉德终产物。但是,已证实形成了二羰基(3,4-二羟基-2-氧杂双醛,1-羟基丁烷-2,3-二酮和4-羟基-2-氧杂双醛)和羟基羰基(丙酮醇),表明存在不稳定的反应性美拉德中间体。结果证实,β-二羰基裂解是1-deoxyhexo-2,3-diulose降解中非常重要
