Starch amylase practical
Webb10 mars 2024 · Starch is a polysaccharide comprising glucose monomers joined in α-1,4 linkages. Its basic chemical formula is (C6H10O5)n. The simplest form of starch is the linear polymer amylose, as shown in the picture above. Salivary amylase, encoded by the gene AMY1, is a major component of human saliva that initiates carbohydrate digestion … WebbIodine Visually identify on a starch agar plate with the reagent added if starch has been degraded. Blue- not degraded Clear- starch degraded, microbe contains amylase Explain how Mannitol salt agar is selective. Mannitol salt agar contains a high (7.5%) salt concentration, making it selective.
