Bird’s nest

Cybullol (377), previously reported as a metabolite of Bird s Nest fungi (c/. Vol. 7, p. 95), and geosmin (379), a degradation product of cybullol and the fungal metabolite responsible for the earthy aroma of freshly ploughed soil, have been synthesized by the routes outlined in Schemes 36 and 37. ...

This scene is a very important plot sequence. It introduces us to the character of Celia, prepares for Corvino s betrayal of an Italian s honor, and sets the scene for Volpone s greatest trick. The reader must remember that the action started in the fox s lair, moved into the open of the streets of Venice, and is now located in the bird s nest. 

To make the eggs, tint 1/4 cup gumpaste a desired color and roll it into egg shapes, with one end slightly tapered. Fill a small bowl with either lemon juice or a clear alcohol such as vodka, and add a pinch of metallic gold dust. Dip die brush in the mixture. Pull the brisdes of the brush back and then release them, so that the metallic liquid splatters the egg. Let the eggs dry. Place in the bird s nest. 

The most common cause of accidental poisoning with carbon monoxide is a fire, stove, or boiler that is inadequately ventilated. When it is lit, it produces the toxic gas which accumulates in the house, especially in modern homes which are often double-glazed and have little ventilation, and especially in the winter. One reason for poor ventilation may be birds nesting in the chimney, which decreases the availability of air. In a recent case a family lit a fire in a rented holiday cottage, but unbeknown to them the chimney had become blocked with a bird s nest, and all of them died of carbon monoxide poisoning. 

For synthetic purposes, NeuSAc has been isolated from a number of natural sources, including edible bird s nest (2-11% sialic acid by weight) [S-7] and submaxillary gland mucins which contain as much as 1S-2S% sialic acid on a dry weight basis [8, 9]. However the need for a more convenient source of NeuSAc has led to the investigation of both enzymic and chemical methods of preparation.

Abscisic acid (ABA) (65), an important plant-growth regulator in higher plants, has been identified, for the first time, as an authentic metabolite of a fungus Cercospora rosicola). Further research on the constituents of bird s nest fungi cf.

What can seem confusing is the fact that with other words ending in s we often use an apostrophe to indicate possession (bird s nest). The apostrophe in this case is being used instead of saying the nest of the bird it is a kind of shorthand. The apostrophe placed before the final s is the singular possessive form (bird s nest) and the apostrophe placed after the s is the plural possessive form (birds nests). 

An unusual diterpenoid, cyathin A3 (121). has been isolated from the bird s nest fungus, Cyathus helenae. Its structure, which followed from a careful examination of the n.m.r. spectrum supported by an X-ray analysis, represents a unique cyclization and rearrangement of geranylgeranyl pyrophosphate (122).

The rare bird s nest fungus Cyathus intermedius produces the yellow xanthone pigment (391) in small amounts when grown in laboratory fermentations 56). The structure (391) was confirmed by synthesis involving regioselective hydroxylation of l-hydroxy-6,8-dimethylxan-thone (Scheme 65). It seems likely that the xanthone (391) arises in the fungus from an octaketide derived anthraquinone precursor.
