Molecular Formula
C165H185N20O30
3Physical Characteristics
bluish pigment found in cyanobacteria fluorescen
ce red molecular weight264kDa maximum
absorption 615-620 nm maximum emission650
nm storage4oC(do not freeze) molecular weight
between 70,000 and 110,000 daltons Abs 1 616nm
73.0
4Chemical Characteristics
water soluble cant exist in the membrane like
carotenoids possesses cyclooxygenase-2
inhibitory activity hepatoprotective
agent hydroxyl radical scavenger accessory
pigment to chlorophyll a form clusters that
adhere to the membrane is particular to which
cells it attaches to so its easy to track down
5Potential Benefits to Humans
positive effects on liver mocrosomal lipid
peroxidation antioxidant anti-inflammatory immu
ne enhancement properties fluorescent properties
that help researcher in immuno assay kits Used
as a coloring agent in biological
research anti-arthritic
Problems
phycocyanin helps cyanobacteria blooms to live
in drinking water reservoirs, and other places
that are not safe to humans
6Functions and Roles in Biofilms
absorbs orange light and emits red light (615
and 640 nm max) Accounts for 20 of the protein
in cyanobacteria very stable protein nitrogen-st
oring molecule Attaches itself to
photosynthesizing membranes aids
photosynthesis
How composition determines the role
phycocyanin consists of very stable
proteins it absorbs the light thats needed for
photosynthesis in the biofilm, and emits the
light that isnt needed
7Interesting Facts
cost 1mg 49 1g 49,000 Crystal
Structure crystals belong to the cell group
R3 ab180.26A, c61.24A alphabeta90ogamma120
o the word phycocyanin uses 11 letters
determined by Patterson research techniques
using molecular model of C-Phycocyanin
