beta-Alanyl-L-lysine
This compound belongs to the family of Hybrid Peptides. These are compounds containing at least two different types of amino acids (alpha, beta, gamma, delta). KEIO_ID A127
Gamma-glutamyl-L-putrescine
Gamma-glutamyl-L-putrescine is involved in the putrescine II degradation pathway. γ-glutamyl-L-putrescine reacts with H2O and O2 to produce γ-glutamyl-γ-aminobutyraldehyde, H2O2, and NH4+. γ-glutamyl-L-putrescine is formed from an ATP-driven reaction between putrescine, L-glutamate. Gamma-glutamyl-L-putrescine is involved in the putrescine II degradation pathway.
Propionylcarnitine
Propionylcarnitine is an acylcarnitine. More specifically, it is an propanoic 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. Propionylcarnitine is therefore classified as a short chain AC. As a short-chain acylcarnitine propionylcarnitine 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. In particular propionylcarnitine is elevated in the blood or plasma of individuals with methylmalonic academia/methylmalonyl-CoA mutase deficiency (PMID: 26454439, PMID: 25750861, PMID: 31622506, PMID: 30712249), propionic academia/mitochondrial propionyl-CoA carboxylase deficiency (PMID: 31715057, PMID: 28915261), obesity and Type 2 Diabetes Mellitus (PMID: 30186675), cobalamin C deficiency (PMID: 25367534), chronic heart failure (PMID: 22622056), diastolic heart failure (PMID: 26010610), and systolic heart failure (PMID: 26010610). It is also decreased in the blood or plasma of individuals with familial Mediterranean fever (PMID: 29900937) and type 2 diabetes Mellitus (PMID: 19369366). It is also decreased in the urine of individuals with obesity (PMID: 26910390). Propionylcarnitine is also found to be associated with propionic acidemia, which is an inborn error 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]. Propionylcarnitine is present in high abundance in the urine of patients with Methylmalonyl-CoA mutase (MUT) deficiency, (together with Methylmalonic acid). MUT is a mitochondrial enzyme that catalyzes the isomerization of methylmalonyl-CoA to succinyl-CoA (OMIM 609058 ) [HMDB] Propionyl-L-carnitine is a carnitine derivative and has a high affinity for muscular carnitine transferase. Propionyl-L-carnitine increases cellular carnitine content, thereby allowing free fatty acid transport into the mitochondria. Propionyl-L-carnitine alleviates the symptoms of PAD through a metabolic pathway, thereby improving exercise performance[1].
Alanyllysine
Alanyllysine is a dipeptide composed of alanine and lysine. It is an incomplete breakdown product of protein digestion or protein catabolism. Some dipeptides are known to have physiological or cell-signaling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis.
Lysylalanine
Lysylalanine is a dipeptide composed of lysine and alanine. It is an incomplete breakdown product of protein digestion or protein catabolism. Dipeptides are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Some dipeptides are known to have physiological or cell-signalling effects although most are simply short-lived intermediates on their way to specific amino acid degradation pathways following further proteolysis.
