Draw a portion of the polymer formed by condensation of 1,2-ethanediol and maleic acid (IUPAC name cis-butenedioic acid). This, and similar polymers, are copolymerized with styrene to form the polyester resins, which are widely used to make structural plastic moldings. [Pg.251]

Glovsky et al. observed an anticomplementary activity for levopimaric acid (45), a derivative of abietic acid, and prepared a number of synthetic derivatives such as maleopimaric acid (46) and fumaropimaric acid (47), being Diels-Alder substitution products of levopimaric acid v ith maleic anhydride or fumaric acid, respectively [28, 29]. Maleic acid is cis-butenedioic acid, fumaric acid is trans-butenedioic acid. Maleopimaric acid inhibited complement-mediated haemolysis via classical path-way activation (45% inhibition at a concentration of 500 iM), Fumaropimaic acid inhibited in vivo complement-dependent systemic Frossman, cutaneous Frossman, and reverse passive Arthus reactions. These pimaric acid derivatives have already been included in earlier reviews on complement-active compounds [8, 30]. The... [Pg.150]

Biochemists know these two forms of butenedioic acid by different (non-systematic) names. Fumaric acid (trans-butenedioic acid) is an intermediate in the Krebs cycle, an essential part of aerobic respiration for energy release in cells (Chapter 15, and Chapter 23 on the accompanying website). Maleic acid (cis-butenedioic acid) is an inhibitor of reactions involved in the interconversion of amino acids in the liver. These different biological roles are a consequence of the molecules different shapes and their interactions with the enzymes involved in metabolic pathways. [Pg.703]

Data on the concentration of dicarboxylic acid anions in subsurface water are much more limited than those on monocarboxylic acid anions and some results are controversial. C2 through Cio saturated acid anions have been reported in addition to maleic acid (cis-butenedioic acid) (Surdam et al. 1984 Kharaka et al. 1986 Barth 1987 MacGowan and Surdam 1988, 1990). Reported concentrations of dicarboxylic acid anions range widely from 0 to 2540 mg/1 but mostly are less than a few lOOmg/1. Concentrations of these species in formation waters are probably limited by several factors, including the very low solubility of calcium oxalate and calcium malonate (Kharaka et al. 1986 Harrison and Thyne 1992), and the susceptibility of these dicarboxylic acid anions to thermal decomposition (MacGowan and Surdam 1988 Crossey 1991). [Pg.53]
