They used amino acids made with isotopes and fed them to the rats to answer this.

Built up means a thing/subjects increases instead of decrease, it builds up overtime getting stronger, to build up they had to add water molecules and proteins.

2 amino acids take 1 water molecule away and it bonds into a protein in the rat's body. Then it gets used as energy
