How Come Your Mom Lets You Have Your Own Yellow Pigment?

GEE BILL! HOW COME YOUR MOM LETS YOU HAVE YOUR OWN YELLOW PIGMENT? Vibrational spectroscopic analyses of unique yellow feather pigments (spheniscins) in penguins Daniel B. Thomas Cushla M. McGoverin, Kevin J. McGraw, Helen F. James and Odile Madden Published: 06 June 2013 https://doi.org/10.1098/rsif.2012.1065 Abstract Many animals extract, synthesize and refine chemicals for colour display, where a range of compounds and structures can produce a diverse colour palette. Feather colours, for example, span the visible spectrum and mostly result from pigments in five chemical classes (carotenoids, melanins, porphyrins, psittacofulvins and metal oxides). However, the pigment that generates the yellow colour of penguin feathers appears to represent a sixth, poorly characterized class of feather pigments. This pigment class, here termed 'spheniscin', is displayed by half of the living penguin genera; the larger and richer colour displays of the pigment are highly attractive. Using Raman and mid-infrared spectroscopies, we analysed yellow feathers from two penguin species (king penguin, Aptenodytes patagonicus, macaroni penguin, Eudyptes chrysolophus) to further characterize spheniscin pigments. The Raman spectrum of spheniscin is distinct from spectra of other feather pigments and exhibits 17 distinctive spectral bands between 300 and 1700 cn. Spectral bands from the yellow pigment are assigned to aromatically bound carbon atoms, and to skeletal modes in an aromatic, heterocyclic ring. It has been suggested that the penguin pigment is a pterin compound: Raman spectra from yellow

Sent via form submission from Deuxmoi Subject: Emma D'arcy public pissing Message: Heard from someone who went to Ruskin school of art with Emma that they did a performance art piece whoh involved them going into a popular Uk coffee chain and relieving themselves on the seats. It was supposed to be anti-capitalist, but left minimum wage workers having to clean up after our posh art school student.
