Depsipeptides
Grenada
An island of the West Indies. Its capital is St. George's. It was discovered in 1498 by Columbus who called it Concepcion. It was held at different times by the French and the British during the 18th century. The British suppressed a native uprising in 1795. It was an associate state of Great Britain 1967-74 but became an independent nation within the British Commonwealth in 1974. The original name referred to the Feast of the Immaculate Conception but it was later renamed for the Spanish kingdom of Granada.

Peptides, Cyclic
Porifera
The phylum of sponges which are sessile, suspension-feeding, multicellular animals that utilize flagellated cells called choanocytes to circulate water. Most are hermaphroditic. They are probably an early evolutionary side branch that gave rise to no other group of animals. Except for about 150 freshwater species, sponges are marine animals. They are a source of ALKALOIDS; STEROLS; and other complex molecules useful in medicine and biological research.
Molecular Structure
Cyanobacteria
A phylum of oxygenic photosynthetic bacteria comprised of unicellular to multicellular bacteria possessing CHLOROPHYLL a and carrying out oxygenic PHOTOSYNTHESIS. Cyanobacteria are the only known organisms capable of fixing both CARBON DIOXIDE (in the presence of light) and NITROGEN. Cell morphology can include nitrogen-fixing heterocysts and/or resting cells called akinetes. Formerly called blue-green algae, cyanobacteria were traditionally treated as ALGAE.
