The protein tropomyosin is found primarily in striated muscle and participates in muscle contraction. Genetic mutations can affect the structure of the tropomyosin molecules produced, causing a number of diseases-including various forms of cardiomyopathy as well as arthrogryposis multiplex congenita and nemaline myopathy. What is tropomyosin? Tropomyosin is a protein found in the human body … Tropomyosin: Structure, Function & Diseases
Guanosine triphosphate, as a nucleoside triphosphate, is an important energy store in the organism along with adenosine triphosphate. It mainly provides energy during anabolic processes. Furthermore, it activates many biomolecules. What is guanosine triphosphate? Guanosine triphosphate (GTP) represents a nucleoside triphosphate composed of the nucleotide base guanine, the sugar ribose, and three phosphate residues linked … Guanosine Triphosphate: Function & Diseases
For human mineral metabolism, it is important to get enough of the minerals we need from food. Of some minerals, humans need larger amounts. They are therefore also called bulk elements in nutritional science. The remaining minerals are called trace elements. What is mineral metabolism For human mineral metabolism, it is important to get enough … Mineral Metabolism: Function, Tasks, Role & Diseases
The biocatalyst sulfite oxidase causes the conversion of toxic sulfur compounds from the breakdown of amino acids into nontoxic sulfates. It is essential for life and is therefore found in all organisms. If its function is disturbed by a genetic defect, sulfite oxidase deficiency occurs. Even in otherwise healthy patients, too much sulfite in the … Sulfite Oxidase: Function & Diseases
Insulin secretion or insulin secretion is the release of the vital hormone insulin by the pancreas. What is insulin secretion? Insulin secretion or insulin secretion is the release of the vital hormone insulin by the pancreas (pancreas). Insulin is produced exclusively in the beta cells of the islets of Langerhans located in the pancreas, from … Insulin Secretion: Function, Role & Diseases
Anabolism refers to anabolic metabolic processes in the organism. Thereby, anabolic and catabolic metabolic processes are closely connected. A build-up of substances always consumes energy. What is anabolism? Anabolism characterizes the build-up of energy-rich and complex compounds from simple molecules under energy input, e.g. in the intestine. Anabolism and catabolism are always linked in metabolic … Anabolism: Function, Tasks, Role & Diseases
Ribose is a sugar that is very abundant in nature. Ribose is a component of ribonucleic acid and nucleotides. The human body is able to synthesize ribose itself. What is ribose? Ribose is a simple sugar (monosaccharide) consisting of five carbon atoms (pentose) and a group of aldehydes. The structural formula of ribose is H2COH-HCOH-HCOH-HCOH-COH. … Ribose: Function & Diseases
Kearns-Sayre syndrome (KSS) was first systematically described in 1958 and is one of the very rare genetic mitochondrial disorders. KSS has a core symptomatology with few symptoms that occurs in all patients. During life, other severe diseases are added depending on which tissues are affected by the mitochondrial defects. They must be treated separately. What … Kearns-Sayre Syndrome: Causes, Symptoms & Treatment
Membrane permeability characterizes the permeability of molecules through cell membranes. All cells are demarcated from intercellular space by biomembranes and simultaneously contain cell organelles that are themselves surrounded by membranes. The permeability of membranes is necessary for the smooth flow of biochemical reactions. What is membrane permeability? Membrane permeability characterizes the permeability of molecules through … Membrane Permeability: Function, Role & Diseases
In membrane transport, substances pass through a biological membrane or are actively transported through membranes. Unlike active transport, diffusion is the simplest membrane transport pathway and requires no additional provision of energy. Disorders of membrane transport are associated with a variety of different diseases. What is membrane transport? Membrane transport is when substances pass through … Membrane Transport: Function, Role & Diseases
