What is phycoerythrin in biology?
What is phycoerythrin in biology?
Phycoerythrin (PE) is a red protein-pigment complex from the light-harvesting phycobiliprotein family, present in red algae and cryptophytes, accessory to the main chlorophyll pigments responsible for photosynthesis.
What is the color of Xanthophyll?
yellow
Xanthophyll (pronounced ZAN-tho-fill) – yellow. Carotene (pronounced CARE-a-teen) – gold, orange. Anthocyanin (pronounced an-tho-SIGH-a-nin) – red, violet, can also be bluish.
What color does Phycobilins reflect?
The combination of phycobilin and chlorophyll produces the characteristic blue-green colour from which these organisms derive their popular name.
What colors do phycobilins reflect?
The phycobilins are especially efficient at absorbing red, orange, yellow, and green light, wavelengths that are not well absorbed by chlorophyll a.
Is phycoerythrin is present in Fucus?
Fucus. Hint: Biological pigments are called pigments or Bio chromes. Phycoerythrin is commonly called red protein pigment. As the name indicates it is present in red algae and cryptophytes.
Where is phycoerythrobilin found in the body?
Phycoerythrobilin is a red phycobilin, i.e. an open tetrapyrrole chromophore found in cyanobacteria and in the chloroplasts of red algae, glaucophytes and some cryptomonads.
Where are the double bonds located in phycoerythrobilin?
For example, phycoerythrobilin has seven double bonds in the main conjugated system and absorbs maximally in the green region of the spectrum; phycocyanobilin has nine such double bonds and its λmax occurs in the red region (see the structures of these compounds in Fig. 5-9 ).
What kind of chromophore is phycobilin found in?
Infobox references. Phycoerythrobilin is a red phycobilin, i.e. an open tetrapyrrole chromophore found in cyanobacteria and in the chloroplasts of red algae, glaucophytes and some cryptomonads.
How are phycobiliproteins different from other tetrapyrroles?
Phycobiliproteins consist of pigmented phycobilins, which are linear tetrapyrroles. Different combinations of the two principal phycobilins – phycoerythrobilin (red) and phycocyanobilin (blue) – that absorb different regions of wavelengths, give different absorption spectra (Lobban and Harrison, 1994; Table 6.4 ).
