UI MeSH Term Description Entries
D010397 Penicillanic Acid A building block of penicillin, devoid of significant antibacterial activity. (From Merck Index, 11th ed) Acid, Penicillanic
D010406 Penicillins A group of antibiotics that contain 6-aminopenicillanic acid with a side chain attached to the 6-amino group. The penicillin nucleus is the chief structural requirement for biological activity. The side-chain structure determines many of the antibacterial and pharmacological characteristics. (Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p1065) Antibiotics, Penicillin,Penicillin,Penicillin Antibiotics
D011199 Potentiometry Solution titration in which the end point is read from the electrode-potential variations with the concentrations of potential determining ions. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
D004590 Electrophoresis, Paper Electrophoresis in which paper is used as the diffusion medium. This technique is confined almost entirely to separations of small molecules such as amino acids, peptides, and nucleotides, and relatively high voltages are nearly always used. Paper Electrophoresis
D013844 Thiazoles Heterocyclic compounds where the ring system is composed of three CARBON atoms, a SULFUR and NITROGEN atoms. Thiazole
