The term "amyloid," used to describe protein misfolding diseases like Alzheimer's, was originally coined from amylum in 1854 because early researchers mistakenly identified these brain deposits as starch.
In food preparation, it is widely used as a for soups, sauces, and gravies. When heated with water, the granules undergo gelatinization , which improves the texture and "mouthfeel" of food products. Industrial and Medical Significance Beyond the kitchen, amylum has extensive applications: amylum
Utilized in drilling fluids and petroleum refining processes. The term "amyloid," used to describe protein misfolding
Chemically, amylum is a polysaccharide consisting of numerous glucose units joined by glycosidic bonds. Its molecular formula is , and it typically exists in two forms: A linear polymer of glucose units linked by Amylopectin: A highly branched polymer with linkages at branching points. Amylum is stored in plant structures as specialized
Amylum is stored in plant structures as specialized granules (SGs), which vary in size and shape depending on the species. For instance, rice starch granules are among the smallest and are typically angular or polygonal. Common Sources and Culinary Uses Amylum is found in large amounts in various staple foods: Wheat, rice, maize (corn), and cereals. Tubers and Roots: Potatoes, cassava (manioc), and sago. Legumes: Lentils and beans.
