  Composition for the diagnostic visualization of neoplastic tissues - Patent 4113850
A process as claimed in claim 1, wherein the dicarboxylic acid or tricarboxylic acid added is a member selected from the group consisting of isocitric acid, cis-aconitic acid, alpha-ketoglutaric acid, oxalosuccinic acid, citric acid, aspartic acid, oxaloacetic acid, malic acid and glutamic acid.
A dicarboxylate or tricarboxylate from the group isocitrate, cis-aconitate, alpha-ketoglutarate, oxalosuccinate, citrate, aspartate, oxaloacetate, malate and glutamate is preferred as the ligand of the central metal ion (.sup.99m Tc.sup.4+ or.sup.111 In.sup.3+).
In the case of the indium ion or indium chloride the use of an alkali metal salt of the dicarboxylic or tricarboxylic acid is sometimes sufficient to neutralize the originally relatively strongly acidic solution.

 Patent 6,673,574
Significant quantities of acid (with which the peptide active agent is intermixed) then reduce the activity of neutral to basic-acting proteases in the intestine (e.g., luminal or digestive protease and proteases of the brush border membrane) by lowering pH below the optimal activity range of these intestinal proteases.
Examples of these are acid salts of acetylglutamic acid, alanine, arginine, asparagine, aspartic acid, betaine, carnitine, carnosine, citrulline, creatine, glutamic acid, glycine, histidine, hydroxylysine, hydroxyproline, hypotaurine, isoleucine, leucine, lysine, methylhistidine, norleucine, ornithine, phenylalanine, proline, sarcosine, serine, taurine, threonine, tryptophan, tyrosine and valine.
Preferred granules may also consist of an acid core, surrounded by a uniform layer of organic acid, a layer of enhancer and a layer of peptide that is surrounded by an outer layer of organic acid.

So called because the first four substances involved (citric acid, cis-aconitic acid, isocitric acid, and oxalosuccinic acid) are all tricarboxylic acids; from oxalosuccinate, the others are, in order, a-ketoglutarate, succinate, fumarate, l-malate, and oxaloacetate, which condenses with acetyl-CoA (from fatty acid degradation) to form citrate (citric acid) again.

Sulfur occurs in coenzyme A; the enzyme helper derived from the B vitamin pantothenic acid and cysteine, which assists in the burning of fat and carbohydrate in energy metabolism.
Coenzyme A serves as a carrier of acyl groups in enzymatic reactions of fatty acid oxidation and pyruvate oxidation, and is involved in the acylation of choline to form acetylcholine.
Biotin participates in the metabolism of aspartic acid, in the decarboxylation of oxalacetic, oxalosuccinic, and succinic acids, and is required for carbon dioxide fixation in microbes.
