Ornithine transcarbamylase deficiency also known as OTC deficiency is the most common urea cycle disorder in humans. Ornithine transcarbamylase , the defective enzyme in this disorder, is the final enzyme in the proximal portion of the urea cycle , responsible for converting carbamoyl phosphate and ornithine into citrulline .
Inborn errors of metabolism are often referred to as congenital metabolic diseases or inherited metabolic disorders. [2] Another term used to describe these disorders is "enzymopathies". This term was created following the study of biodynamic enzymology , a science based on the study of the enzymes and their products.
Negative nitrogen balance is associated with burns, serious tissue injuries, fever, hyperthyroidism, wasting diseases, and periods of fasting. A negative nitrogen balance can be used as part of a clinical evaluation of malnutrition. [3] Nitrogen balance is a method traditionally used to measure dietary protein requirements. [4]
[11] [12] Specifically, it is a deficiency, excess, or imbalance of energy, protein and other nutrients which adversely affects the body's tissues and form. [13] Malnutrition is a category of diseases that includes undernutrition and overnutrition. [14] Undernutrition is a lack of nutrients, which can result in stunted growth, wasting, and ...
However, these physical symptoms can also be caused by numerous other stresses, such as deficiencies in other nutrients, toxicity, herbicide injury, disease, insect damage or environmental conditions. Therefore, nitrogen deficiency is most reliably detected by conducting quantitative tests in addition to assessing the plant's visual symptoms.

Citrullinemia belongs to a class of genetic diseases called urea cycle disorders. The urea cycle is a sequence of chemical reactions taking place in the liver . These reactions process excess nitrogen , generated when protein is used for energy by the body, to make urea, which is excreted by the kidneys .
