when was this substance which resists the process discovered?
1921.
Introduction
Insulin was the first peptide hormone discovered. Frederick Banting and Charles Herbert Best, working in the laboratory of J.J.R. Macleod at the University of Toronto, were the first to isolate insulin from dog pancreas in 1921. 
the primary high energy molecule in human metabolism is Adenosine triphosphate (ATP) what is catabolism? It is the set of metabolic processes that breaks down large molecules. which hormones are related to it? Cortisol, glucagon, adrenaline, cytokines, orexin and melatonin. what is the emotional response due to the third one? Fear. how does the first hormone related to metabolism of glucose? Cortisol stimulates the synthesis of 'new' glucose from non-carbohydrate sources; this is known as gluconeogenesis.. is process resisted by insulin? Yes.

Insulin [SEP] Introduction
Insulin was the first peptide hormone discovered. Frederick Banting and Charles Herbert Best, working in the laboratory of J.J.R. Macleod at the University of Toronto, were the first to isolate insulin from dog pancreas in 1921. Frederick Sanger sequenced the amino acid structure in 1951, which made insulin the first protein to be fully sequenced. The crystal structure of insulin in the solid state was determined by Dorothy Hodgkin in 1969. Insulin is also the first protein to be chemically synthesised and produced by DNA recombinant technology. It is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system.
