QuestionAnswer
how is a disaccharide formed? linking of 2 sugars by an O-glycosidic bond
bond in sucrose? 1-2 glycosidic bond glucose (C1) and fructose (C2)
how is sucrose a non-reducing sugar? 1-2 glycosidic bond takes up both anomeric carbons so disaccharide cannot open so cannot react with reducing agents
lactose? 1,4-glycosidic link
glycogen? alpha-1-4, glycosidic bonds branches roughly every 10 units in an alpha-1,6 glycosidic bond
cellulose? isomer of alpha-amylose beta glycosidic links inverted flip 180 interval to facilitate formation of glycosidic link
hyaluronic acid? component in synovial fluid and vitreous humour of eye, skin moisture and ageing, occurs in capsules surrounding bacteria
hyaluronic acid is also known as? hyaluronate
describe linkages in hyaluronate 250-25000 beta1-4 linked disaccharide units consiisting of D-glucuronic acid and N-acetyl-D-glucosamine linked by a beta 1-3 bond
how does penicillin kill susceptible bacteria specifically inhibiting transpeptidase
transpeptidase? catalyses final step in cell wall biosynthesis, cross linking of peptidoglycan
by inhibiting transpeptidase, what is the result? weak cell wall and osmotic lysis of bacterium
