Micronutrient deficiencies are considered a public health problem worldwide. For over 30 years it has been estimated that more than two billion people of all ages are affected by this burden, [1] while a recently published study based on individual-level biomarker data estimated that there are 372 million children aged 5 years and younger, and 1.2 billion non-pregnant women of reproductive age ...
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 .
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 .
[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 ...
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]
A young cabbage plant exhibiting nitrogen deficiency. Nitrogen deficiency is a deficiency of nitrogen in plants. This can occur when organic matter with high carbon content, such as sawdust, is added to soil. [1] Soil organisms use any nitrogen available to break down carbon sources, making nitrogen unavailable to plants. [1]

Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. [1] Poor nutrition is a chronic problem often linked to poverty, food security , or a poor understanding of nutritional requirements. [ 2 ]
