Description | Leucylleucine, also known as LL or H-L-leu-L-leu-OH, belongs to the class of organic compounds known as peptides. Peptides are compounds containing an amide derived from two or more amino carboxylic acid molecules (the same or different) by formation of a covalent bond from the carbonyl carbon of one to the nitrogen atom of another. Leucylleucine has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make leucylleucine a potential biomarker for the consumption of these foods. Leucylleucine is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on Leucylleucine. |
