Nitrogen Balance = Nitrogen intake - Nitrogen loss

Nitrogen intake = Protein intake (g/day) / 6.25

Urinary Urea Nitrogen (UUN) determined with 24hr urine collection

Nitrogen loss = UUN (g/day) + 4g (to account for random nitrogen loss)

If the excretion of nitrogen balance exceeds the nitrogen intake the condition is called what?

Positive nitrogen balance occurs when the total nitrogen excreted in the urine, feces and sweat is less than the total nitrogen ingested. Positive nitrogen balance must exist for new tissue to be synthesized. When dietary protein intake or total energy intake is inadequate to maintain tissues total nitrogen balance, negative nitrogen balance occurs and new tissue is unable to be synthesized.


What would describe the state of nitrogen balance of a person who ingested 16 g of food nitrogen and lost 19 g of nitrogen?

The person is in negative nitrogen balance because they lost more nitrogen (19 g) than they ingested (16 g). Negative nitrogen balance indicates that the body is breaking down more protein than it is synthesizing, which can be seen in conditions like starvation or illness.


Is Pregnancy is an example of negative nitrogen balance?

No, it is an example of positive nitrogen balance. This is because a pregnant women is in need of protein to allow growth of the child, and in order to build protein you need Nitrogen. Therefor pregnancy is considered positive nitrogen balance.


What would be the usual state of nitrogen balance for healthy infants children and pregnant women?

Healthy infants usually have a positive nitrogen balance due to rapid growth and development, while healthy children tend to have a neutral nitrogen balance as they are usually in a state of balance with the amount of nitrogen consumed and excreted. Pregnant women may have a slightly positive nitrogen balance to support the growth and development of the fetus.


Does anabolism create a positive or negative nitrogen balance?

Anabolism creates positive nitrogen balance. That means sort of body building. Catabolism creates negative nitrogen balance. That means loss of proteins from your body.


Is nitrogen balance important for building muscle?

Nitrogen balance is not important in the process of building muscle, but testing for nitrogen can help determine whether protein consumption is optimal.


Is positive protein balance and positive nitrogen balance the same?

Yes

Will the nitrogen balance be negative or positive if a person ingested 16g of food nitrogen and lost 19g of nitrogen?

The nitrogen balance will be negative since the person is losing more nitrogen (19g) than they are ingesting (16g), resulting in a net loss of 3g of nitrogen. A negative nitrogen balance indicates that the body is breaking down more protein than it is building, which can result in muscle loss and other negative consequences.


Is pregnancy a negative nitrogen balance?
