This is a page consisting of many different proteins, enzymes, and other compounds that may be helpful in creating lifeforms. Most of these are real, but some compounds here specifically originate from Sagan 4. If you have a chemical that you feel should be added, feel free to add it to the list for others.
Adhesives, Silks and Glues
Effect: Gossamer is protein fiber made to make silk. It can be used to build webs, cocoons, nests or just to help climb.
Effect: Lignin is chemical that keeps flora leaves stiff. This stiffness makes the flora unattractive to most herbivores, and allows the leaves to grow taller without bending. It also makes the leaves pure yellow in color.
Divisives, Acids and Dissolvers
Effect: Chitinase are digestive enzymes that break down glycosidic bonds in chitin.
Effect: Cellulase is a strong chemical that dissolves cellulose.
Effect: An enzyme and a catalyst in turning starch into sugar.
Effect: Enzymes that digest keratin.
Bioluminescents, Phosphorescents, and Pigments
Effect: Luciferin is a biological substance which glows when oxidized. Some types of Luiferin emit UV and IR instead of visible light.
Bacteriorhodopsin & Retinal
Effect: Retinal is a type of vitamin A that can be used as a method of photosynthesis. It absorbs yellow-green light and gives off a purple hue. It operates alongside bacteriorhodopsin, a protein that acts as a proton pump.
Example(s): Hexapodia (Kingdom)
Effect: An iron based oxygen-carrying metalloprotein. It is the most efficient known respiratory pigment. Blood is tinted dark red.
Example(s): Binucleid Worms
Effect: An iridium-based oxygen-carrying molecule. It functions at roughly 50% of the efficiency of haemoglobin, but the process takes longer. Blood is tinted yellow when oxygenated but appears dull orange when deoxygenated. This molecule is light-sensitive and degrades in light when oxygenated. (Also notably capable of hydrogen-carrying as well)
Effect: A cobalt-based oxygen-carrying molecule. It functions at roughly 40% of the efficiency of haemoglobin, but degrades much faster. Blood is tinted yellow-amber when oxygenated but appears light pink when deoxygenated.
Effect: A copper-based oxygen-carrying molecule. It functions at roughly 25% of the efficiency of haemoglobin. Blood is tinted blue-green when oxygenated but appears clear when deoxygenated.
Effect: An iron-based oxygen-carrying molecule. It functions at roughly 25% of the efficiency of haemoglobin. Blood is tinted purple-violet when oxygenated but appears clear when deoxygenated.
Effect: An iron-based oxygen-carrying molecule. It is much less efficient than haemoglobin. Blood is tinted green in low concentrations, but vivid red in high concentrations.
Effect: A manganese-based oxygen-carrying molecule. It is much less efficient than haemoglobin. Blood is tinted brown.
Effect: A substance that inhibits ice-crystal growth.
Effect: A Protein that many organisms descended from Carpotesta Pellícere uses to attract prey by leaving it out in the open for a cell to confuse as food.
