Dehydronuciferine
Dehydronuciferine is found in coffee and coffee products. Dehydronuciferine is an alkaloid from the leaves of Nelumbo nucifera (East Indian lotus). Dehydronuciferine is an isoquinoline alkaloid. Dehydronuciferine is a natural product found in Nelumbo nucifera with data available. Dehydronuciferine is isolated from the leaves of Nelumbo nucifera Gaertn, a acetylcholinesterase (AChE) inhibitor with an IC50 of 25 μg/mL[1].

N-Fructosyl isoleucine
Fructose aminoacids are naturally occurring compounds derived from D-fructose and L-aminoacids. They are amadori products resulting from sugar-aminoacid interactions in food products, especially cooked foods [CCD] N-(1-Deoxy-1-fructosyl)isoleucine is classified as a Natural Food Constituent (code WA) in the DFC.
Koenimbine
Koenimbine is found in herbs and spices. Koenimbine is an alkaloid from leaves and fruits of Murraya koenigii (curryleaf tree
Phenylalanylglutamine
Phenylalanylglutamine is a dipeptide composed of phenylalanine and glutamine. 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.
Glutaminylphenylalanine
Glutaminylphenylalanine is a dipeptide composed of glutamine and phenylalanine. 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.
Phenylalanyl-Gamma-glutamate
Phenylalanyl-Gamma-glutamate is a dipeptide composed of phenylalanine and gamma-glutamate. 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. This dipeptide has not yet been identified in human tissues or biofluids and so it is classified as an Expected metabolite.
N-(1-Deoxy-1-fructosyl)leucine
Fructose aminoacids are naturally occurring compounds derived from D-fructose and L-aminoacids. They are amadori products resulting from sugar-aminoacid interactions in food products, especially cooked foods [CCD] N-(1-Deoxy-1-fructosyl)leucine is classified as a Natural Food Constituent (code WA) in the DFC.
3,4,5-Trihydroxypentanoylcarnitine
3,4,5-trihydroxypentanoylcarnitine is an acylcarnitine. More specifically, it is an 3,4,5-trihydroxypentanoic 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. 3,4,5-trihydroxypentanoylcarnitine is therefore classified as a short chain AC. As a short-chain acylcarnitine 3,4,5-trihydroxypentanoylcarnitine 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].
