Amyloid Beta: Origin, Structure And Toxicity

Beta amyloid (AB) or beta amyloid peptide (ABP) is the name given to peptides of 39-43 amino acids and between 4-6 kDa in molecular weight that are the product of the metabolism of the amyloid precursor protein (APP) when processed by the amyloidogenic route. The term amyloid (starch-like) refers to the fact that the deposits

Ovalbumin: Structure, Functions, Denaturation

The ovalbumin is the most abundant protein in the “clear” eggs of birds. It belongs to the family of proteins known as “serpin” or “serine protease inhibitor”, which is a highly diverse group of eukaryotic proteins (includes more than 300 homologous proteins). It was one of the first proteins isolated with great purity and, thanks

Conductive Fabrics: Characteristics And Functions

The conductive tissues of plants are responsible for orchestrating the long-distance passage of nutrients through the different structures of the plant organism. Plants that present conductive tissues are called vascular plants. There are two classes of conductive tissues: xylem and phloem . The xylem is made up of tracheal elements (the tracheids and tracheas) and

Glucans: Structure, Characteristics And Functions

The glucans are perhaps the most abundant carbohydrates in the biosphere. Most make up the cell wall of bacteria, plants, yeasts, and other living organisms. Some make up the reserve substances of vertebrates . All glucans are made up of one type of repeating monosaccharide: glucose. However, these can be found in a great variety
