The definition of α-synuclein α-synuclein is a soluble protein expressed in the pre-synaptic and perinuclear regions of the central nervous system. It is closely related to the pathogenesis and related dysfunction of Parkinson’s disease. And α-synuclein is the main component of Louis’s body. The  properties of α-synuclein The structure of the α-synuclein is largely dependent

Basic introduction of Epithelium Epithelium is composed of dense epithelial cells and a very small amount of interstitial cells constitute the basic organization of animals. Generally connected to each other into a film-like, covered in the body surface, or lining the body of the hollow cavity surface, and body cavity surface. The arrangement of a

Introduction to dopamine Dopamine is secreted by the brain and can affect a person’s mood. Arvid Carlsson determined that the role of dopamine as the brain transmitters made him win the 2000 Nobel Prize in Medicine. Dopamine is a neurotransmitter that is used to help cells transmit pulsed chemicals. This brain endocrine is mainly responsible

Introduction to platelets Platelet is one of the visible components of mammalian blood and is a biologically active small cytoplasm that is shed from the cytoplasmic cleavage of megakaryocytes from bone marrow. Small size, irregular shape, a plasma membrane, no nuclei, generally round, smaller than red blood cells and white blood cells. Platelets are seen

Introduction to Agglutinin Agglutinin refers to a variety of plants, invertebrates and higher animals in the purification of glycoproteins or binding sugar protein, because it can agglutinate red blood cells (blood type substances), hence the name Agglutinin. Commonly used as phytoagglutin (PNA), usually named after its extracted plants, such as Conconvalina (Conconvalina, ConA), wheat germ

The concept of cholecystokinin Cholecystokinin(CCK) is a polypeptide consisting of 33 amino acids isolated from the small intestine extract. To stimulate the gallbladder to shrink and excite the role of pancreatic enzyme secretion. Overview of cholecystokinin Cholecystokinin was certified and purified in 1928 and in 1943. There are many chemical structures of natural cholecystokinin, CCK-33,

Introduction to retinol Retinol, also known as vitamin A, is the first to be found in vitamins. There are two kinds of vitamin A. There are two kinds of retinol, one is retinol (vitamin A), is the first form of vitamin A (only in animal food); the other is carotene, in vivo changes to vitamin

Basic introduction of cartilage Cartilage is a dense colloidal substance that is stronger but resilient than bones. It is the main component of many protozoa such as shark bones. On the human body, nose and ears and containing cartilage used to fill tissue. A translucent, elastic tissue that forms the bones of vertebrate embryos and

Definition of calmodulin A protein that binds to calcium. Calcium ion is called intracellular second messenger, its concentration changes can regulate cell function, this regulation is mainly through the calmodulin. Introduction to calmodulin Calmodulin is a cytosolic protein in eukaryotic cells, consisting of 148 amino acids in a single polypeptide with a relative molecular mass

Introduction to Glucocorticoids Glucocorticoid (GCS) is a class of steroid hormones secreted by the gluteal band of the adrenal cortex, mainly cortisol, which regulates the biosynthesis and metabolism of sugars, fats, and proteins. Inhibition of immune response, anti-inflammatory, anti-virus, anti-shock effect. Called “glucocorticoid” because of its regulation of the activity of carbohydrate metabolism is the

An Overview of Hemocyanin Hemocyanin, also known as hemocyanin, is a multifunctional protein that was previously called respiratory protein, but recent studies have shown that the protein is involved in energy storage, maintenance of osmotic pressure and regulation of the molting process. Introduction of Hemocyanin Hemocyanin is a free blue respiratory pigment found in the

The definition of threonine Threonine was isolated and identified by W.C. Rose in 1935. In 1936, Meger studied the structure of its space, because the structure and Su sugar similar, it will be named threonine. Threonine has four isomers, naturally occurring and the physiological role of the body is L-threonine. The nature of L-threonine L-threonine
