Pentadecylic acid, also known as pentadecanoic acid or C15:0, is an odd-chain saturated fatty acid. Its molecular formula is CH 3 (CH 2) 13 CO 2 H. It is a colorless solid. A laboratory preparation involves permanganate oxidation of 1-hexadecene (CH 3 (CH 2) 13 CH=CH 2). [2] It is one of the most common odd-chain fatty acids, although it is ...
VLCAD (very long-chain-acyl-dehydrogenase) deficiency is exclusively linked to genetic mutations in DNA. A change of the gene that codes for very long-chain-acyl-CoA-dehydrogenase (VLCAD) results in a deficiency or malfunction of the produced VLCAD enzyme. [7] This mutation occurs on chromosome 17 and can be altered via a variety of pathways. [4]
The side effects of cyproterone acetate (CPA), a steroidal antiandrogen and progestin, including its frequent and rare side effects, have been studied and characterized.It is generally well-tolerated and has a mild side-effect profile, regardless of dosage, when it used as a progestin or antiandrogen in combination with an estrogen such as ethinylestradiol or estradiol valerate in women.
Carnitine-acylcarnitine translocase deficiency is a rare, autosomal recessive metabolic disorder that prevents the body from converting long-chain fatty acids into energy, particularly during periods without food. [1] Carnitine, a natural substance acquired mostly through the diet, is used by cells to process fats and produce energy.
Methylmalonic acidemias have varying diagnoses, treatment requirements and prognoses, which are determined by the specific genetic mutation causing the inherited form of the disorder. [3] The first symptoms may begin as early as the first day of life or as late as adulthood. [4] Symptoms can range from mild to life-threatening. [1]
With appropriate treatment, most individuals with glucocorticoid deficiency can lead normal lives and have a good prognosis. [4] However, it is important to closely monitor hormone levels and adjust medication accordingly to prevent complications such as adrenal crisis or over-replacement side effects. [1]
This treatment replenishes Ig subtypes that the person lacks, is given at frequent intervals for life, and is thought to help reduce bacterial infections and boost immune function. [25] Before therapy begins, plasma donations are tested for known blood-borne pathogens, then pooled and processed to obtain concentrated IgG samples.
Holocarboxylase synthetase deficiency is an inherited metabolic disorder in which the body is unable to use the vitamin biotin effectively. [2] This disorder is classified as a multiple carboxylase deficiency , a group of disorders characterized by impaired activity of certain enzymes that depend on biotin.
