Excess amino acids are not stored as such -- any excess would be converted to

fat. In a sense our muscles are our amino acid store, which are constantly

breaking down and building up -- hopefully in balance. Although the body is

always using a mixture of fuels, (resting muscles and heart prefer fatty

acids; quick fast twitch muscles use glucose, etc.), the body would

preferentially use carbohydrate sources first for glucose production/use

before either amino acids or glycerol. Carbohydrate sources use the

glycolytic pathway, whereas amino acids and glycerol are non-carbohydrate

sources the body uses in gluconeogenisis to make glucose.
