1. Canavanine

   L-(+)-(S)-Canavanine is a non-proteinogenic amino acid found in certain leguminous plants. It is structurally related to the proteinogenic α-amino acid L-arginine, the sole difference being the replacement of a methylene bridge (-CH2- unit) in arginine with an oxa group (i.e., an oxygen atom) in canavanine. Canavanine is accumulated primarily in the seeds of the organisms which produce it, where it serves both as a highly deleterious defensive compound against herbivores (due to cells mistaking it for arginine) and a vital source of nitrogen for the growing embryo. The related L-canaline is similar to ornithine.

1. canavanine

   Canavanine is a non-proteinogenic amino acid and analog of arginine that is found in certain plants, especially in the seeds of leguminous species. It is known for its antimicrobial, antifungal, and insecticidal properties and can cause toxic effects in organisms not adapted to its ingestion. In humans, it can interfere with protein synthesis and can pose risks if consumed in large amounts. It is named after Canavalia, the plant genus in which it was first identified.

1. Canavanine

   L---Canavanine is a non-proteinogenic α-amino acid found in certain leguminous plants. It is structurally related to the proteinogenic α-amino acid L-arginine, the sole difference being the replacement of a methylene bridge in arginine with an oxa group in canavanine. Canavanine is accumulated primarily in the seeds of the organisms which produce it, where it serves both as a highly deleterious defensive compound against herbivores and a vital source of nitrogen for the growing embryo. The mechanism of canavanine's toxicity is that organisms that consume it typically mistakenly incorporate it into their own proteins in place of L-arginine, thereby producing structurally aberrant proteins that may not function properly. Some specialized herbivores tolerate L-canavanine either because they metabolize it efficiently or avoid its incorporation into their own nascent proteins. An example of this ability can be found in the tobacco budworm Heliothis virescens the larvae of which can tolerate massive amounts of dietary canavanine. These larvae fastidiously avoid incorporation of L-canavanine into their nascent proteins. In contrast, larvae of the tobacco hornworm Manduca sexta can only tolerate tiny amounts of dietary canavanine because their arginine-tRNA ligase has little, if any, discriminatory capacity. No one has examined experimentally the arginine-tRNA synthetase of these organisms. But comparative studies of the incorporation of radiolabeled L-arginine and L-canavanine have shown that in Manduca sexta, the ratio of incorporation is about 3 to 1.
