The crystal structure of lithium glycolate monohydrate

Disodium D-3-phosphoglycerate, a substrate to phosphoglycerate kinase

“…The C-C bond lengths are well within the spread of reported values (Fenn & Marshall, 1972;Shefter & Trueblood, 1965). The C(2)-O(3) length is in agreement with those in other a-hydroxy acids (Colton & Henn, 1965;Clark, 1964).…”

Structure of manganese(II) glycolate dihydrate

“…There is also a tendency for the 0(3) or 0(6) hydroxy atoms to lie in this plane. Similar trends have been noted in other structures containing the glycolate moiety (Goli~ & Speakman, 1965;Colton & Henn, 1965;Johnson, Gabe, Taylor & Rose, 1965;Fischinger & Webb, 1969;Prout et al, 1968;Ellison, Johnson & Levy, 1971;Pijper, 1971) as well as in other hydroxycarboxylate salts of Mn II, such as citrate (Carrell & Glusker, 1973), malate (Karipides & Reed, 1976) and gluconate (Lis, 1979). The conformational phenomena of a-hydroxycarbonyl systems have been investigated by Newton & Jeffrey (1977) using ab initio molecular-orbital theory.…”

Stereochemistry of the .alpha.-hydroxycarboxylic acids and related systems

“…The angle 03 is not defined for the anion. 6 See footnote b, Table II. The total energy for 0i = 180°, 02 = 0°i s -301.64808 au.…”
