A-Amino valerate

Iso-valeric acid is one of the isomeric five carbon acids. It is 3-methyl butanoic acid. Valine is the alphchdimmo derivative of it. a-Amino Valeric Acid, CH3—CH2—CH2—CH(NH2)—COOH...

A large body of literature exists concerning the measurement of protein oxidation during aging in different models. Most of the studies measure the formation of protein-bound carbonyls [88-108]. Other authors suggested or used other amino acid modifications, like tyrosine oxidation products such as dityrosine, o-tyrosine or nitrotyrosine [109-112], the formation of 5-hydroxyl-2-amino valeric acid [ 113], or methionine sulfoxide formation [112].

Isoleucine and valine. The first four reactions in the degradation of isoleucine and valine are identical. Initially, both amino acids undergo transamination reactions to form a-keto-/T methyl valerate and a-ketoiso valerate, respectively. This is followed by the formation of CoA derivatives, and oxidative decarboxylation, oxidation, and dehydration reactions. The product of the isoleucine pathway is then hydrated, dehydrogenated, and cleaved to form acetyl-CoA and propionyl-CoA. In the valine degradative pathway the a-keto acid intermediate is converted into propionyl-CoA after a double bond is hydrated and CoA is removed by hydrolysis. After the formation of an aldehyde by the oxidation of the hydroxyl group, propionyl-CoA is produced as a new thioester is formed during an oxidative decarboxylation.

Chemically, valrubicin differs from its doxorubicin parent by the addition of a Ci4-valerate ester and a 3 -trifluoroacetamide (Fig. 42.17). The carbon-rich valerate obviously is lipophilic, and acylation of the daunosamine amino group makes the 3 -substituent un-ionizable. Both of these structural changes promote a more rapid and extensive penetration into tumor cells.

Bidstrup and Geankoplis, 1963 (43). The experiments were for concentration up to 0.1 N in the carboxylic acid series (formic, acetic, propionic, butyric, valeric and caproic). Their resulting correlation, which was shown to be equally applicable to the corresponding a-amino carboxylic acids, is simply the Hilke and Chang s equation (1.18) but with the constant 7.4 replaced for 6.6, i.e. c...
