Lysylaspartic acid
Lysylaspartic acid is a dipeptide composed of lysine and aspartic acid. 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.
Aspartyllysine
Aspartyllysine is a hydrophilic dipeptide composed of aspartic acid 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. Aspartyllysine is widely distributed in nature and is present in wheat, fish, and other nutrients. It has been demonstrated to be absorbed by the intestinal H+/peptide transporter PepT1. It is excreted by the kidney-specific high-affinity H+/peptide cotransport system (PMID:1982012, 9922316, 7589991). alpha-Aspartyl-lysine is an hydrophilic dipeptide widely distributed in nature. It is present in wheat, fish and other nutrients. It has been demonstrated to be absorbed aided by the intestinal H+/Peptide transporter PepT1.

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. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.

Succinyl Carnitine
Succinylcarnitine is an acylcarnitine. More specifically, it is an succinic 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. Succinylcarnitine is therefore classified as a short chain AC. As a short-chain acylcarnitine Succinylcarnitine 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), it has been identified in the human placenta (PMID: 32033212 ). 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].

O-Methylmalonylcarnitine
O-Methylmalonylcarnitine is an acylcarnitine. More specifically, it is an methylmalonic acid ester of carnitine. Acylcarnitines were first discovered more than 70 year ago (PMID: 13825279).

Epiheterodendrin is a member of the class of compounds known as cyanogenic glycosides. Cyanogenic glycosides are glycosides in which the aglycone moiety contains a cyanide group. Epiheterodendrin is soluble (in water) and a very weakly acidic compound (based on its pKa). Epiheterodendrin can be found in barley, which makes epiheterodendrin a potential biomarker for the consumption of this food product.
