Are structures or compounds that are made from amino acids.

Nutritionally protein is consumed on a daily basis from a wide variety of foods

The protein is digested and while in the stomach are broken down into smaller polypeptides

Proteases are enzymes which are important during beakdown

Proteins contain energy 4 kilocalories per gram

Once protein is consumed and digested into the blood system it can be converted by the liver and kidney into amino acids

Of the 20 amino acids, 9 require dietary consuption and are unable to be synthesized within the body

Gluconeogenesis

Is a metabolic pathway for the production of glucose

This is only for non-carbohydrate substances such as protein, glycerol, amino acid, lactate and a few others
