Respiratory pigments are molecules that increase the carrying capacity of oxygen in blood. Explore hemoglobin, the most common respiratory pigment, and organisms that do not use hemoglobin. What Is a Respiratory Pigment? A respiratory pigment is any molecule that increases the oxygen carrying capacity...
These are usually an integral part of the structure of the chloroplast lamellae, but sometimes, as in bluegreen algae, they are homogeneously distributed throughout that part of the protoplasm called the "chromatoplasm." Pigments are molecules, which absorb light. The most efficient organic ...

Dyes and pigments are complex organic molecules that are widely utilized in different industries leading to effluent discharge, thus polluting water and disturbing the aquatic life. A wide range of physicochemical and biological methods have been introduced for the dye remediation. Constant research devel...
Given that methanol and isopropanol are able to form hydrogen bonds with water and thus act as dehydrants (e.g. methanol is routinely used to fix proteins34,35), the volume contraction and corresponding pitch reduction induced by washing the ‘dry’ CNC microparticles with a polar solvent was...
The absorbed colors are the ones you don't see -- you see only the colors that come bouncing back to your eye. This is known as subtractive color, and it's what happens with paints and dyes. The paint or dye molecules absorb specific frequencies and bounce back, or reflect, other ...
The process of pigmentation doesn't entail any form of chemical amalgamation between the molecules of dyes and those of pigments. Additionally, pigments are notably insoluble in water and other solvents, evading any form of dissolution. This contrasts vividly with dyes, where a chemical liaison form...
For that reason these pigments are generally not suitable in artists' colors, especially watercolors.Disazo Condensation. A small group of 17 azo pigments formed, like the diarylides, of two coupled arylide molecules: but these are joined in condensation with a bifunctional hydrocarbon molecule —...
Another group less important are the betalains and quinones. The carotenoids are molecules formed by isoprenoids units and the most important used as colorant are the alpha and beta carotene which are precursors of vitamin A, and some xantophylls as astaxanthin. The pigment more used in the ...
