Aldehyde and hydrocyanic acid unite and form a substance which has been shown to be the nitrile of a-hydroxypropionic acid. The addition must, therefore, take place according to the equation,—... [Pg.196]

Lactic Acid, CH3.CHOH.COOH, a-hydroxypropionic acid, exists in three forms, two of which are optically active. The acid contains an asymmetric carbon atom and its optical activity is traced to this cause as in the case of amyl alcohol, which has been considered at some length (77). [Pg.285]

Wislicenus used the name geometrical isomerism for this type of isomerism the name stereoisomerism was introduced by Victor Meyer (see p. 756). The present position is that there are three lactic acids (i) J-lactic acid present in flesh-juice, (ii) Z-lactic acid, which does not occur naturally and was first separated from rf/-lactic acid by F. Schardinger, and T. Purdie and J. W. Walker, and (hi) //-lactic acid, a racemic compound, optically inactive, and formed in lactic fermentation. Lactic acid is a-hydroxypropionic acid, CH3-CH(0H) C02H j8-hydroxypropionic acid, CH2(0H)-CH2 C02H, is hydracrylic acid. [Pg.761]

Lactic acid (1790) (milk acid, a-hydroxypropionic acid) n. CH3CHOH COOH. A colorless or yellowish liquid with several applications in plastics. Reacted with glycerine, it forms an alkyd resin. It is a catalyst for vinyl polymerizations, and an additive for phenolic casting resins. It has a bp of 122°G/15mmHg, mp of 18°C, and Sp gr of 1.2 Also known as alpha-hydroxypropionic acid and milk acid. [Pg.561]

There has been considerable recent interest in the reductions of [Fe(CN)6]. The electron exchange with A -propyl-l,4-dihydronicotinamide is catalyzed by alkali metal ions. The increase in reaction rate is attributed to the polarizability of M and the observed linear free energy relationship is discussed. An outer-sphere mechanism is postulated in the oxidation of phenothiazines. A free radical mechanism involving the alcohol anion is invoked in the reaction of 1-and 2-propanol in aqueous alkaline media, the kinetic order being unity for [Fe(CN)6], OH, and alcohol concentrations. Catalysis by metal ions has also been observed in the presence of copper(II) and ruthenium(III) complexes. In the oxidation of a-hydroxypropionic acid in alkaline media,a Cu(II)-ligand complex is formed which is oxidized slowly to a copper(III) species. Alkaline ferricyanide oxidizes butanol, the process being catalyzed by chlororuthenium complexes.The rate law is consistent with oxidation of the alcohol by the Ru(III) followed by reoxidation of the catalyst by [Fe(CN)6]. The rate law is of the form ... [Pg.48]

According to Woolley (654), lycomarasmin might contain an -hy-droxyalanine derivative. The toxin can therefore be looked upon as a N-(a-[ -hydroxypropionic acid])-glycylasparagine, which therefore classifies it as a heteromeric peptide. [Pg.76]
