Beta-hydroxyisovaleroylcarnitine
3-Hydroxyisovalerylcarnitine is structual derivative of 3-hydroxyisovaleric acid and carnitine. Due to its increased concentration in blood, 3-hydroxyisovalerylcarnitine (C5OH-I) is an important indicator for the diagnosis of organic acidemias in newborns (PMID: 18088573). Analysis of acylcarnitines by tandem mass spectrometry (MS/MS) has recently been used to screen newborns for organic acidemias and fatty acid oxidation defects (PMID: 7494654, 9216448, 11427446, 12127323, 14578311). These diseases cause the accumulation of acyl-CoA, which is esterified to acylcarnitine by carnitine acyltransferase. Acylcarnitine is then eliminated in the urine, thus acylcarnitine concentration serves as an excellent indicator for these diseases (PMID: 6361812). 3-Hydroxyisovalerylcarnitine (C5OH-I) is an indicator for diagnoses of multiple carboxylase deficiency (MCD), 3-methylcrotonyl-CoA carboxylase deficiency and 3-hydroxy-3-methylglutaryl-CoA lyase deficiency (PMID: 18088573), which are inborn errors of metabolism.
hydroxyisovaleroyl carnitine
hydroxyisovaleroyl carnitine is classified as a member of the Acyl carnitines. Acyl carnitines are organic compounds containing a fatty acid with the carboxylic acid attached to carnitine through an ester bond. hydroxyisovaleroyl carnitine is considered to be practically insoluble (in water) and acidic. hydroxyisovaleroyl carnitine is a fatty ester lipid molecule
2-Hydroxyisovalerylcarnitine
2-Hydroxyisovalerylcarnitine belongs to the class of organic compounds known as acylcarnitines. These are organic compounds containing a fatty acid with the carboxylic acid attached to carnitine through an ester bond. 2-Hydroxyisovalerylcarnitine is an extremely weak basic (i. e. Human blood levels of 2-hydroxyisovalerylcarnitine were reported to be influenced by genetic variants in the gene HLCS which codes for the enzyme holocarboxylase synthetase (PMID: 26401656). Holocarboxylase synthetase deficiency (OMIM: 253270), also called HLCS deficiency, is a rare inborn error of metabolism (IEM) and autosomal recessive disorder caused by a defective holocarboxylase synthetase. Individuals with HLCS deficiency are unable to utilize biotin effectively.
(2S,3R)-3-Hydroxy-2-methylbutanoylcarnitine
(2S,3R)-3-Hydroxy-2-methylbutanoylcarnitine is an acylcarnitine. More specifically, it is an (2S,3R)-3-hydroxy-2-methylbutanoic acid ester of carnitine. Acylcarnitines were first discovered more than 70 year ago (PMID: 13825279). It is believed that there are more than 1000 types of acylcarnitines in the human body. The general role of acylcarnitines is to transport acyl-groups (organic acids and fatty acids) from the cytoplasm into the mitochondria so that they can be broken down to produce energy. This process is known as beta-oxidation. According to a recent review [Dambrova et al. 2021, Physiological Reviews], acylcarnitines (ACs) can be classified into 9 different categories depending on the type and size of their acyl-group: 1) short-chain ACs; 2) medium-chain ACs; 3) long-chain ACs; 4) very long-chain ACs; 5) hydroxy ACs; 6) branched chain ACs; 7) unsaturated ACs; 8) dicarboxylic ACs and 9) miscellaneous ACs. Short-chain ACs have acyl-groups with two to five carbons (C2-C5), medium-chain ACs have acyl-groups with six to thirteen carbons (C6-C13), long-chain ACs have acyl-groups with fourteen to twenty once carbons (C14-C21) and very long-chain ACs have acyl groups with more than 22 carbons. (2S,3R)-3-Hydroxy-2-methylbutanoylcarnitine is therefore classified as a short chain AC. As a short-chain acylcarnitine (2S,3R)-3-Hydroxy-2-methylbutanoylcarnitine is a member of the most abundant group of carnitines in the body, comprising more than 50\\% of all acylcarnitines quantified in tissues and biofluids (PMID: 31920980). Some short-chain carnitines have been studied as supplements or treatments for a number of diseases, including neurological disorders and inborn errors of metabolism. Carnitine acetyltransferase (CrAT, EC:2.3.1.7) is responsible for the synthesis of all short-chain and short branched-chain acylcarnitines (PMID: 23485643). The study of acylcarnitines is an active area of research and it is likely that many novel acylcarnitines will be discovered in the coming years. It is also likely that many novel roles in health and disease will be uncovered. An excellent review of the current state of knowledge for acylcarnitines is available at [Dambrova et al. 2021, Physiological Reviews].

3-Hydroxyisovalerylcarnitine
3-hydroxyisovalerylcarnitine is an O-acylcarnitine having 3-hydroxyisovaleryl as the acyl substituent. It has a role as a human metabolite. It is functionally related to a 3-hydroxyisovaleric acid. 3-Hydroxyisovalerylcarnitine is a specific amino acid derivative that belongs to the class of compounds known as carnitines. This molecule plays a crucial role in the transport of fatty acids into the mitochondria for oxidation, a key process in energy production. The name "3-Hydroxyisovalerylcarnitine" reflects its chemical structure: it consists of a carnitine moiety attached to a 3-hydroxyisovaleryl group. The term "3-hydroxyisovaleryl" refers to a side chain derived from a pentanoic acid (a five-carbon acid) that contains a hydroxyl group (-OH) bonded to the third carbon atom in the chain. This hydroxyl group is critical for the compound's function and is a distinguishing feature of this particular carnitine derivative. 3-Hydroxyisovalerylcarnitine involved in fatty acid metabolism, characterized by its unique hydroxyisovaleryl substituent attached to the carnitine backbone.
