Mono hydroxy succinic acid

The other hydroxy di-basic acids which we shall consider are the hydroxyl substitution products of succinic acid. These hydroxy succinic acids are commonly occurring substances and, both from the standpoint of theory and of practical value, are most important compounds. The mono-hydroxy succinic acid is commonly known as malic acid, and the di-hydroxy compound is the common substance, tartaric acid.

A group of related siderophores comprises the desferri- or deferriferrioxamines (occasionally abbreviated as desferrioxamines) or proferrioxamines. Originally they were obtained from Actinomycetes, mainly Nocardia and Streptomyces spp. (187) and later found to be produced also by Erwinia spp. (several representatives) (e.g. (30a, 113,115,180)), Arthrobacter simplex (B), Chromobacterium violaceum (E) (246a), and by Pseudomonas stutzeri (several) (229a, 246,398). They consist of three (or in rare cases four) mono-N-hydroxy-l,4-diaminobutane (putrescine), mono-iV-hydroxy-l,5-diaminopentane (cadaverine) or (rarely) mono-N-hydroxy-1,3-diaminopropane units connected by succinic acid links. The hydroxylated terminus carries an acetyl or a succinyl (as in the structural formula heading Table 6)... 

The FAD-requiring enzymes in mammalian systems include the D- and L-amino acid oxidases, mono- and diamine oxidases, glucose oxidase, succinate dehydrogenase, a-glycerophosphate dehydrogenase, and glutathione reductase. FMN is a cofactor for renal L-amino acid oxidase, NADH reductase, and a-hydroxy acid oxidase. In succinate dehydrogenase, FAD is linked to a histidyl residue in liver mitochondrial monoamine oxidase, to a cysteinyl residue. In other cases, the attachment is nonco-valent but the dissociation constant is very low.
