Acetylcholine because it binds directly to the DNA
adipose tissue deposits in the body are very high
adipose tissue deposits in the body are very low
apetite is stimulated
apetite is inhibited
apetite is stimulated and adipose tissue deposits are low
apetite is inhibited and adipose tissue deposits are high
