Study Notes
Amino Acids in the Body
- Amino acids play a crucial role in the body as the building blocks of proteins.
- The average protein turnover rate in a 70 kg man is 280-300 grams per day.
Origin of Non-Essential Amino Acids
- Non-essential amino acids are synthesized by the body from other amino acids.
Absorption of Dietary Proteins
- Dietary proteins are absorbed by the body in the form of amino acids, which are then used to build new proteins or repair damaged tissues.
Deficiency of Essential Amino Acids
- A deficiency in essential amino acids can lead to a negative nitrogen balance, muscle wasting, and impaired bodily functions.
Storage Form of Proteins
- The storage form of proteins in the body is in the form of muscle and liver tissue.
Nitrogen Balance
- Nitrogen balance refers to the balance between the amount of nitrogen taken in through protein intake and the amount of nitrogen excreted by the body.
- A positive nitrogen balance indicates that the body is building new proteins, while a negative nitrogen balance indicates that the body is breaking down existing proteins.
