Napalm Napalm Napalm is an incendiary mixture of a gelling agent and a volatile petrochemical (usually gasoline (petrol) or diesel fuel). The title is a portmanteau of the names of two of the constituents of the original thickening and gelling agents: co-precipitated aluminium salts of naphthenic and palmitic acids. Napalm B is the more modern version of napalm (utilizing styrene derivatives) and, although distinctly different in its chemical composition, is often referred to simply as "napalm". Napalm was originally developed in 1942 in a secret laboratory at Harvard University, by a team led by chemist Louis Fieser under the United States
Non-proteinogenic amino acids a methylene group. Diaminopimelic acid is both used as a bridge in peptidoglycan and is used a precursor to lysine (via its decarboxylation). In meteorites and in prebiotic experiments (e.g. Miller–Urey experiment) many more amino acids than the twenty standard amino acids are found, several of which at higher concentrations than the standard ones: it has been conjectured that if amino acid based life were to arise in parallel elsewhere in the universe, no more than 75% of the amino acids would be in common. The most notable anomaly is the lack of aminobutyric acid. The genetic code has been
