C-phycocyanin is a protein-bound pigment soluble in water and found in some blue-green microalgae such as Spirulina, which is used in many countries as a dietary supplement. According to Romay et al. (1998b), phycocyanin shows anti-inflammatory activity in four experimental models of inflammation.
Is Phycocyanin a carotenoid?
Arthrospira platensis is the widely available source of spirulina that contains distinctive natural pigments, including carotenoids and C-phycocyanin (C-PC). … The carotenoid profiles suggested that the commercial spirulina powders originated from two different sources, A. platensis and A.
What is Phycocyanin phycoerythrin?
Abstract. Phycocyanin and phycoerythrin are photosynthetic pigments extracted from microalgae with great biotechnological potential due to their intense colors, fluorescent properties and potential health benefits.
What is Phycobilisomes function?
Phycobilisomes. Phycobilisomes in cyanobacteria and red algae are large antennae complexes that absorb light energy and transfer the energy for use in photosynthesis. These phycobiliprotein complexes absorb much of the visible spectrum and thus benefit the organisms by greatly extending their absorbance capacity.
Is spirulina a fluorescent?
Spirulina platensis is a cyanobacterium which usually lives under high-light conditions. Nonetheless, it is thought to contain the most red-shifted antenna pigment of all known Chl a-containing phototrophic organisms, as shown by its 77 K fluorescence peaking at 760 nm.
What is the predicted color of phycoerythrin?
The red pigment is due to the prosthetic group, phycoerythrobilin, which gives phycoerythrin its red color. Like all phycobiliproteins, it is composed of a protein part covalently binding chromophores called phycobilins.
Is phycoerythrin a pigment?
Phycoerythrin (PE) is a red protein pigment complex produced by the light-harvesting phycobiliprotein family. It is present in red algae and cryptophytes as an accessory to the main chlorophyll pigments responsible for photosynthesis (Ficner and Huber, 1993; van der Weij-De Wit et al., 2006).

Do red algae have Phycobilins?
The red algae were the first lineage of organisms to have true chloroplasts, derived from the endosymbiosis of a cyanobacterium, and so they have the same pigments: chlorophyll a and phycobilins. In particular, the red algae derive most of their coloring from a red phycobilin called phycoerythrin.
Where do you find Phycobiliproteins?
Phycobiliproteins are water-soluble proteins present in cyanobacteria and certain algae (rhodophytes, cryptomonads, glaucocystophytes). They capture light energy, which is then passed on to chlorophylls during photosynthesis.
Is spirulina bad for kidneys?
If you are susceptible to gout attacks or kidney stones, then spirulina may be harmful to you. To avoid excessive uric acid, Beth Israel Deaconess Medical Center suggest limiting the intake of spirulina to 50 grams per day.
Is it good to take spirulina everyday?
Although most research has investigated spirulina’s effects on animals, studies in older adults have shown that it may improve inflammatory markers, anemia, and immune function ( 40 ). Up to 8 grams of spirulina per day is safe, and many people add it to their shakes or smoothies because it comes in powder form.
Does spirulina cause weight gain?
Spirulina is a high-nutrient, low-calorie food that contains a lot of nutrition in a small amount of powder. Introducing spirulina to the diet may help people lose weight without losing nutrition. The results of a 2016 double-blind placebo-controlled trial suggest that spirulina may aid weight management.
What is the function of Phycocyanin in cyanobacteria?
A cyanobacterium is an ancient group of photosynthetic prokaryotes that are thought to be the first organisms to carry out oxygenic photosynthesis. Phycocyanin (PC) is used to capture light energy for photosynthesis, unique to cyanobacteria.
What is the meaning of xanthophylls?
Definition of xanthophyll

What is Phycobilisome in algae?
Abstract. Phycobilisomes are aggregates of light-harvesting proteins attached to the stroma side of the thylakoid membranes of the cyanobacteria (blue-green algae) and red algae. The water-soluble phycobiliproteins, of which there are three major groups, tetrapyrrole chromophores covalently bound to apoprotein.
What pigment gives brown algae its color?
The brown colour of these algae results from the dominance of the xanthophyll pigment fucoxanthin, which masks the other pigments, Chlorophyll a and c (there is no Chlorophyll b), beta-carotene and other xanthophylls.
