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)
No; astronauts have a negative nitrogen balance.
What factors might lead to a positive nitrogen balance?
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.
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.
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.
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.
Anabolism creates positive nitrogen balance. That means sort of body building. Catabolism creates negative nitrogen balance. That means loss of proteins from your body.
Nitrogen balance is not important in the process of building muscle, but testing for nitrogen can help determine whether protein consumption is optimal.
Yes
Negative nitrogen balance is when nitrogen input is less then the output. It is associated with burns, sickness, serious injury, fasting and fevers. By:Chris Lopez
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.
No, it is positive.
