Apple acid

Two Streptomyces strains, S. badius and S. viridosporus, were found to be able to grow on kraft lignin (In-dulin ATR) as sole carbon source. The resulting APPL (Acid Precipitable Polymeric Lignin) was characterized by FTIR and elemental analysis for C, H and N, and was found to contain proteins in addition to a relatively demethoxylated lignin component. The proteins were further characterized by amino acid analysis, while the lignin component was separated by solvent extraction and its molecular weight distribution determined by HPSEC. [Pg.529]

Malic acid (Figure 2.11) is an alpha hydroxy organic acid, widely found in apples and other fruits and is, therefore, sometimes referred to as a fruit acid or, more specifically, an apple acid. It is also found in plants and animals, including humans. Malic acid is also known as hydroxybutaneoic acid or hydroxysuccinic acid. It is a chiral molecule, the naturally occurring... [Pg.35]

This was first obtained from the oxidation of malic acid (apple acid) and takes its name from this. It occurs in the mixed calcium salts obtained during the processing of sugar beet. [Pg.133]

The L-( —)-form of malic acid occurs naturally in apples and other fhiits hence its German name Apfelsdure ( apple acid ). It is an extremely versatile 4-carbon building block possessing an additional carboxyl group at the 4-position that serves as a useful handle easily manipulated to provide a variety of synthetically useful functionalities. [Pg.167]

The chiral malic acid figures strongly in the original discovery of inversion of configuration in the Sn2 reaction. Malic acid is sometimes called apple acid because of its high concentration in apples, nectarines, and some other fruits. In fact, it was first isolated from apple juice as early as 1785. It functions as a molecular carrier of the carbon dioxide absorbed by plants. The CO2 appears in the CHjCOOH group of malic acid. The principal actor in the early mechanistic work on the S>j2 reaction was Paul Walden, a chemist born in 1863 in what is... [Pg.274]
