Nε,Nε,Nε-Trimethyllysine chloride serves as a precursor for gut flora-dependent formation of N,N,N-trimethyl-5-aminovaleric acid (TMAVA).

all-trans-Anhydro Retinol (Anhydrovitamin A) is a metabolite of Vitamin A. all-trans-Anhydro Retinol is used in synthetic multivitamin preparations.

Orotidine 5′-monophosphate is a pyrimidine ribonucleoside and plays a role as an endogenous metabolite of human, E. coli or mouse. Orotidine 5′-monophosphate is an intermediate in the biosynthesis of?uridine monophosphate (UMP). Orotidine 5′-monophosphate can be used for the study of mechanism of orotidine 5′-monophosphate decarboxylase.

Enterostatin (human,mouse,rat) TFA is a pentapeptide mainly formed in the intestine by the cleavage of secreted pancreatic procolipase. Enterostatin ?selectively reduces fat intake, bodyweight, and body fat in vivo.

Atrial natriuretic factor (1-28) (human, porcine) (Atrial natriuretic peptide (1-28)) is an endogenous peptide produced by the heart, involved in blood pressure regulation. Atrial natriuretic factor (1-28) (human, porcine) produces natriuresis, diuresis and vasorelaxation in vivo.

Defensin HNP-1 human is a Human neutrophil peptides (HNPs), involved in endothelial cell dysfunction at the time of early atherosclerotic development.Defensin HNP-1 human can regulate the growth of atherosclerosis.

Defensin HNP-2 human is an endogenous antibiotic peptide and monocyte chemotactic peptide produced by human neutrophils.

Cecropin P1, porcine is an antibacterial peptide originally identified in moths (Hyalophora cecropia) and later in pig intestine.

D-Allothreonine is the D type stereoisomer of Allothreonine. D-Allothreonine is a peptido-lipid derived from bacteria. D-Allothreonine, amide-linked to the D-galacturonic acid, is also a constituent in the polysaccharide.
