      why foods are stored in body as glycogen form in animals? why it can not stored as amino acids or fatty acid or trigleceride?

      They are stored that way – only glucose is stored as glycogen. Whether amino acids get "stored" depends upon how your define the term, and lipids are definitely stored.

      Glycogen is the fastest source of energy, but for sure not the main source of energy.

      amino acids cannot be stored as the nitrogen is toxic.They must be deaminated and excreted as urea.

      Glycogen and triglyceride are storage of energy.

      What you just said about amino acids makes no sense – it’s like saying water can’t be stored because hydrogen is explosive. Amino acids can be sequestered in proteins – whether that is true storage or not is debatable. If you USE amino acids for respiration-derived energy, then you have to deal with freed ammonia. But they aren’t always used, at least not immediately.

      That was probably manis’s point that they cannot be used as immediate source of energy
