Common Name5-amino valeric acid betaine
Description5-amino valeric acid betaine (5-AVAB), also known as delta-valerobetaine and δ-valerobetaine, belongs to the class of organic compounds known as straight chain fatty acids. These are fatty acids with a straight aliphatic chain. 5-AVAB is also classified as a betaine. Betaines are neutral chemical compounds with a positively charged cationic functional group, such as a quaternary ammonium or phosphonium cation. 5-AVAB is a weakly acidic compound (based on its pKa). There is considerable confusion over the nomenclature of this molecule, with widely varying synonyms appearing in databases and the literature (PMID: 30158657 ). 5-AVAB is sometimes (incorrectly) referred to as simply “aminovaleric acid betaine” or “trimethylaminovaleric acid” or TMAVA. The fact that there is a known, unnatural isomer (4-amino valeric acid betaine) requires that the position of the betaine/acidic group be properly identified. 5-AVAB has also been called 5-trimethylaminovaleric acid (PMID: 921982 ) and 5-[trimethylammonio]pentanoate (PMID: 24571165 ) in earlier literature. 5-AVAB is associated with the consumption of foods or diets that are rich in whole grains and vegetables (PMID: 30158657 ). 5-AVAB is a gut microbial metabolite that arises from the breakdown of trimethyllysine (PMID: 35365608 ). Trimethyllysine is particularly abundant in vegetables and grains as a free amino acid (PMID: 24454731 ), although it may also be derived from the endogenous breakdown of proteins in the body during starvation or fasting (PMID: 24454731 ). 5-AVAB tends to accumulate in metabolically active tissues including the heart, muscle and brown adipose tissue (PMID: 30158657 ). 5-AVAB has similar molecular structure with meldonium (mildronate), a drug that inhibits β-oxidation of fatty acids (PMID: 30158657 ). Meldonium has been associated with improved cardiac mitochondrial function after ischemia and is considered a potential performance enhancing drug (PMID: 27465696 ). Meldonium has been shown to have beneficial effects in cardiovascular, neurological and metabolic diseases due to its anti-ischaemic and cardioprotective properties, which are ascribed mainly to its inhibition of β-oxidation and its activation of glycolysis. Among athletes, meldonium is used with the purpose of increasing recovery rate or exercise performance (PMID: 27465696 ). In particular, meldonium protects cardiac mtDNA from oxidative stress during exhaustive exercise (PMID: 33930377 ). Like meldonium, 5-AVAB appears to block the cell membrane carnitine transporter (OCTN2) and reduces biosynthesis of L-carnitine from γ-butyrobetaine by inhibiting γ-butyrobetaine hydroxylase (PMID: 30158657 ). This leads to reduced β-oxidation of fatty acids. For healthy individuals, 5-AVAB may provide a beneficial effect with improved cardiac metabolism and improved recovery from physical exercise. However, its effect may be deleterious for individuals with heart disease. In particular, 5-AVAB has been found to be elevated in patients with heart failure and its levels correlate with an increased risk of cardiac mortality and heart transplantation in patients with heart failure (PMID: 35365608 ). Furthermore, 5-AVAB treatment has been shown to aggravate cardiac hypertrophy and dysfunction in high-fat diet-fed mice (PMID: 35365608 ). Overall, 5-AVAB decreases fatty acid oxidation (FAO). FAO is a hallmark of metabolic reprogramming in the diseased heart and contributes to impaired myocardial energetics and contractile dysfunction. A contrarian view of the associative effects of 5-AVAB and heart disease is that 5-AVAB accumulates in heart tissues in diseased individuals as a protective chemical. The more diseased the heart, the more 5-AVAB is generated to stave off mitochondrial collapse in the heart tissue. Clearly more research on the cause and effects of 5-AVAB is needed.
