The IUPAC numerical multiplier is a system of prefixes used in chemistry to indicate the number of atoms or groups in a molecule.
The tetra-peptide tuftsin (Thr–Lys–Pro–Arg), has been reported to affect a wide variety of biological responses in neutrophils and mononuclear phagocytes and also phagocytosis. It has also been reported that a tetra-peptide with the amino acid sequence, RGDS, that is from the cell-binding domain of the fibronectin molecule, is capable of ...
The band was named after a tiny African primate the band found very cute called "bush babies", and a kind of fish the band liked called a "neon tetra" (taking one word from each of those names). [5] The band thought the name sounded "tribal". [5] The band's debut 7-inch EP, "Too Many Creeps", was released in 1980 on 99 Records. [1]
Tetrachloroethylene, also known as perchloroethylene [a] or under the systematic name tetrachloroethene, and abbreviations such as perc (or PERC), and PCE, is a chlorocarbon with the formula Cl 2 C=CCl 2.
Numbering of the various substituents and bonds with their locants. If there is more than one of the same type of substituent/double bond, a prefix is added showing how many there are (di – 2, tri – 3, tetra – 4, then as for the number of carbons below with 'a' added at the end)

Proline (symbol Pro or P) [4] is an organic acid classed as a proteinogenic amino acid (used in the biosynthesis of proteins), although it does not contain the amino group-NH 2 but is rather a secondary amine .
Oxidation of alcohol to aldehyde with TPAP (0.06 eq.) and N-methylmorpholine N-oxide (1.7 eq.) with molecular sieves in dichloromethane. [1]Ruthenium tetroxide is a highly aggressive oxidant, but TPAP, which is its one-electron reduced derivative, is a mild oxidizing agent for the conversion of primary alcohols to aldehydes (the Ley oxidation).
