Iodine deficiency is a lack of the trace element iodine, an essential nutrient in the diet.It may result in metabolic problems such as goiter, sometimes as an endemic goiter as well as congenital iodine deficiency syndrome due to untreated congenital hypothyroidism, which results in developmental delays and other health problems.
Organic acidemia is a term used to classify a group of metabolic disorders which disrupt normal amino acid metabolism, particularly branched-chain amino acids, causing a buildup of acids which are usually not present. [1] The branched-chain amino acids include isoleucine, leucine and valine. [1]
Isoleucine (symbol Ile or I) [1] is an α-amino acid that is used in the biosynthesis of proteins.It contains an α-amino group (which is in the protonated −NH + 3 form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO − form under biological conditions), and a hydrocarbon side chain with a branch (a central carbon atom bound to three other ...
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. Finally, inborn errors of metabolism were studied for the first time by British physician Archibald Garrod (1857–1936), in 1908.
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 ...
Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems. [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.
[12] [33]: 57 Finally, sleep disorders, coeliac disease, and side effects of medications may also explain symptoms. [12] Joint and muscle pain without swelling or inflammation is a common feature of ME/CFS, but is more closely associated with fibromyalgia. Modern definitions of fibromyalgia not only include widespread pain but also fatigue ...
The use of the term hypoxia appears to be relatively recent, with the first recorded use in scientific publication from 1945. Previous to this the term anoxia was extensively used for all levels of oxygen deprivation. Investigation into the effects of lack of oxygen date from the mid 19th century. [130]
