Glycine is thought to be a hepatic detoxifier of a number endogenous and xenobiotic organic acids. [44] Bile acids are normally conjugated to glycine in order to increase their solubility in water. [45] The human body rapidly clears sodium benzoate by combining it with glycine to form hippuric acid which is then excreted. [46]
Pyridine is a basic heterocyclic organic compound with the chemical formula C 5 H 5 N. It is structurally related to benzene, with one methine group (=CH−) replaced by a nitrogen atom (=N−). It is a highly flammable, weakly alkaline, water-miscible liquid with a distinctive, unpleasant fish
The amino acid glycine contributes all its carbon (2) and nitrogen (1) atoms, with additional nitrogen atoms from glutamine (2) and aspartic acid (1), and additional carbon atoms from formyl groups (2), which are transferred from the coenzyme tetrahydrofolate as 10-formyltetrahydrofolate, and a carbon atom from bicarbonate (1). Formyl groups ...
Purine is obtained in good yield when formamide is heated in an open vessel at 170 °C for 28 hours. [17] This remarkable reaction and others like it have been discussed in the context of the origin of life. [18] Patented August 20, 1968, the current recognized method of industrial-scale production of adenine is a modified form of the formamide ...
The sweetness of 5% solution of glycine in water compares to a solution of 5.6% glucose or 2.6% fructose. [16] A number of plant species produce glycosides that are sweet at concentrations much lower than common sugars. The most well-known example is glycyrrhizin, the sweet component of licorice root, which is about 30 times sweeter than sucrose.

Six other amino acids are considered conditionally essential in the human diet, meaning their synthesis can be limited under special pathophysiological conditions, such as prematurity in the infant or individuals in severe catabolic distress. [2] These six are arginine, cysteine, glycine, glutamine, proline, and tyrosine.
Quinolinic acid (abbreviated QUIN or QA), also known as pyridine-2,3-dicarboxylic acid, is a dicarboxylic acid with a pyridine backbone. It is a colorless solid. It is the biosynthetic precursor to niacin. [1] Quinolinic acid is a downstream product of the kynurenine pathway, which metabolizes the amino acid tryptophan.
