Textile testing is the process of evaluating the quality and properties of a textile material through a series of tests at various stages of manufacturing. [1] Textile testing, like textiles, is a vast subject. The historical evolution of textile measuring, and testing methods is difficult to consolidate as the subject is scattered and has ...
The Bradford assay uses the spectral properties of Coomassie brilliant blue G-250 to estimate the amount of protein in a solution. [19] A protein sample is added to a solution of the dye in phosphoric acid and ethanol. Under the acid conditions the dye is normally a brownish colour but on binding to the protein the blue form of the dye is produced.
The Bradford protein assay (also known as the Coomassie protein assay) was developed by Marion M. Bradford in 1976. [1] It is a quick and accurate [2] spectroscopic analytical procedure used to measure the concentration of protein in a solution. The reaction is dependent on the amino acid composition of the measured proteins.
Dextrins are a group of low-molecular-weight carbohydrates produced by the hydrolysis of starch [1] and glycogen. [2] Dextrins are mixtures of polymers of D- glucose units linked by α- (1→4) or α- (1→6) glycosidic bonds. Dextrins can be produced from starch using enzymes like amylases, as during digestion in the human body and during ...
Pure starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol. It consists of two types of molecules: the linear and helical amylose and the branched amylopectin. Depending on the plant, starch generally contains 20 to 25% amylose and 75 to 80% amylopectin by weight. [4]
The American Association of Textile Chemists and Colorists (AATCC) develop the test methods the textile industry use to ensure product quality. AATCC is the world's leading not-for-profit association serving textile professionals since 1921. AATCC, headquartered in Research Triangle Park, N.C., USA, provides test method development, quality ...
Detergent powder containing enzymes. Detergent enzymes are biological enzymes that are used with detergents. They catalyze the reaction between stains and the water solution, thus aiding stain removal and improving efficiency. [1] Laundry detergent enzymes are the largest application of industrial enzymes.

This linkage motif contrasts with that for α(1→4)-glycosidic bonds present in starch and glycogen. Cellulose is a straight chain polymer. Unlike starch, no coiling or branching occurs and the molecule adopts an extended and rather stiff rod-like conformation, aided by the equatorial conformation of the glucose residues.
