Information compiled from various sources, especially the original (but occasionally erroneous) Full Chemical List.
It is important to note that the effect of a chemical depends on your creature's genome. The effects listed here apply to typical creatures, especially but not exclusively normal breeds of Norns. Some creatures like Toxic Norns will have completely different reactions to certain chemicals. It is possible for mutations to be introduced which cause an otherwise normal Norn to develop an unusual reaction to a chemical. This can cause positive effects like immunity to a disease or immortality, or it may cause negative effects such as death at birth. Therefore, the tables listed below can only be considered general guidelines, though they will hold most of the time.
NOTE: Do not be alarmed when chemicals marked "bad" appear in your creature's bloodstream, unless they are toxins. Many are normal, they just produce negative effects when injected. Chemicals marked "vital" are necessary to your creature's survival and you may need to inject them if they are lacking, but injecting them when there is already a good supply may have no effect. Also, be warned that the good/bad column does not take into account how your creature will feel, only how it affects the creature's health.
Produced when a creature is suffocating, hungry for carbohytate or drowning. Causes choking sensation and slight injury to muscles. Though this sounds bad, production of lactate is not a bad thing: it's the body's way of telling the creature that they should do something about their inability to breathe, for instance, to get out of the water!
2
Pyruvate
Good
Produced from glucose. Turns ADP into ATP. Injecting ATP or energy would be more direct.
3
Glucose
Good
All food eventually produces glucose. It then becomes pyruvate, and then, one hopes, ATP.
4
Glycogen
Vital
Starch storage chemical. Glycotoxin can deplete this.
5
Starch
Good
Found in high concentration in seeds, and smaller concentration in fruits. Of course, it can also be injected.
6
Fatty acid
Good
This stuff, believe it or not, is actually good. A stage in the breakdown of fat.
7
Cholesterol
Neutral
A by-product of the breakdown of fat. Sometimes converted to Pyruvate and Amino acid
8
Triglyceride
Good
Another stage in the breakdown of fat.
9
Adipose tissue
Good
When your creature needs to store fat for the long-term, the fat becomes this. This is the stuff that makes them fat, but they'll never really be obese.
10
Fat
Good
Fat is actually a good thing. It's found in food and critters.
11
Muscle tissue
Vital
Long-term storage of protein. Inject to counteract effects of muscle toxin.
A waste product (from the breaking down of pyruvate) that is removed from the body by the lungs.
25
Urea
Neutral
Waste product from protein digestion which controls urination. (No, you don't get to see the creatures urinate.)
26
Ammonia
Bad
Nothing to be alarmed about if you see it in your creature's bloodstream, but don't inject it because it's somewhat toxic. It is a waste product which is naturally turned into urea.
ATP is the staple of your creature's bloodstream. Without it, your creature would be dead, and in fact there's an extremely lethal poison that takes advantage of this (ATP Decoupler). ATP is used for almost all bodily functions.
When ATP's energy is used up, it becomes this. There's little point in injecting it (ATP would be the better choice), but its presence in the bloodstream is very normal. When glucose is broken down, ADP becomes ATP.
Produced when the creature is fertile, and ready to mate. Needs opposite sex pheromone to convert it into sex drive.
40
Libido lowerer
neutral
Lowers the sex drive when the creature is not ready to mate for any reason
41
Opposite sex pheromone
Good
This Is produced when a creature senses another creature of the correct Species and sex, the presence of this chemical triggers the convert of arousal potential into sex drive.
Indicates the fertility of a female (no oestrogen, no kisspop). Sharply falling levels of oestrogen indicates the most fertile time for the female.
48
Progesterone
Good
Produced during pregnancy. Triggers egg-laying once it reaches a threshold. A shot of progesterone may help a pregnant norn deliver her child. Progesterone also prevents pregnancy for a short time after the norn lays her egg. Fun fact: injecting progesterone into a female will make her body think she is pregnant, her stomach will grow and her body will change in order to concieve,but don't worry, this will wear off and the creature will return to normal.
Deteriorates the immune system and causes mutations in unborn children.
67
Cyanide
Dangerous
We all know that in real life, taking cyanide is only useful if you want to ensure your death. With creatures, it's no different. Cyanide will slow down the creation of ATP and will therefore kill your creature if you do nothing about it. It does have a cure: sodium thiosulphate, #96.
68
Belladonna
Very bad
Disrupts regulatory functions.
69
Geddonase
Bad
Injected by stinging insects. Destroys adipose tissue.
70
Glycotoxin
Bad
Attacks creature's glycogen. Cure with arnica.
71
Sleep toxin
Neutral
Causes sleepiness. Otherwise harmless to most creatures. Produced by some antigens.
72
Fever toxin
Neutral
Causes a fever. Otherwise harmless to most creatures. Produced by some antigens.
73
Histamine A
Neutral
Causes sneezing, making disease contagious. Otherwise harmless to most creatures. Produced by some antigens.
74
Histamine B
Neutral
Causes coughing, making disease contagious. Otherwise harmless to most creatures. Produced by some antigens.
75
Alcohol
Bad
Causes drunkenness.
78
ATP decoupler
Instant death
ATP decoupler does its evil by taking your creature's ATP and quickly turning it all into ADP. It has a cure (medicine one, #92), but ATP decoupler works very fast, so chance of recovery is infinitesimal. An average creature will die within two seconds upon injection of even the smallest dose.
All antigens are the products of bacterial infections. They can cause organ damage; see C3 Organs to see what antigens attack which organs. Antigens also produce other chemicals. Note that Ettins are immune to all antigens except 0 through 2, and Grendels are immune to all antigens except 6 and 7. Norns should be particularly wary of antigen 5 because it produces "wounded", which can cause death!
Chemicals 102 through 109 are antibodies 0 through 7, corresponding to antigens 0 through 7. Your creature will produce these antibodies on its own, but you can inject them to help combat antigens. Antibodies will only fight the corresponding antigen, for example, if your creature has antigen 5, you must inject antibody 5. You can even inject antibodies before the creature comes across the antigens, so that they're immunized.
Only found in Grendels. Influences decisions on whether or not a particular creature is friend or foe.
119
Ettin nitrate
Neutral
Only found in Ettins. Influences decisions on whether or not a particular creature is friend or foe.
121
Protease
Neutral?
Converts muscle tissue to amino acid (1->4 in default genome)
124
Activase
Neutral?
Not used?
125
Life
Vital
Creature ages as this depletes. A creature dies of old age when it nears zero. Continually injecting this will effectively make your creature immortal.
127
Injury
Good(ish)
Prompts system to heal wounds. However, if it is too high, your Creature's life is endangered.
128
Stress
Bad
Produced when a drive is too high for an extended period of time.
Sometimes drives need to be suppressed when a creature should have other priorities. You should not inject any of these chemicals, because drives produce stress.
