One of a group of phospholipids (nitrogenous phosphorized fatty substances), present in all living cells and particularly evident in nervous tissue. The cephalins consist of glycerol phosphate in which the two free hydroxyls of the glycerol are esterified with fatty acids, and the phosphate forms an ester linkage to the hydroxyl of ethanolamine. The phosphate may be linked to the alpha (end) or beta (middle) hydroxyl of the glycerol portion. The natural isomers are of the alpha form, and have the general formula R.O.CH2.CHOR/.CH2.O.PO2.O.CH2.CH2.NH2, where R and R/ are the acyl residues of long-chain fatty acids, which may be the same or different.

The anterior region or head of insects and other arthropods.

any of a class of chemical substances, some of which have therapeutically useful antibacterial activity, whose structure contains a beta-lactam ring fused to a six-membered ring containing a sulfur and a nitrogen atom. The first of the series, cephalosporin C, was discovered by G. Brotzu in 1955 in the culture broth of a Cephalosporium species found off the coast of Sardinia. Other cephalosporins have been found to be produced by species of soil bacteria (actinomycetes). Many semisynthetic analogs have been tested for antibacterial effect, and several of them have found use as important clinically useful antibacterial agents, some of which may be taken orally for treatment of bacterial infections. The cephalosporins are the second class of beta-lactam antibiotic to be discovered, the first being the penicillins and more recent classes being the thienamycins and sulfazecins. The cephamycins are a variant of cephalosporins with a methoxyl group on the beta-lactam ring, rendering them more resistant to penicillinases. Among the cephalosporins which have been found clinically useful are cephalexin, cephaloridine, and cephalothin.
