Amylose and cellulose are both straight chain polysaccharides containing only D-glucose units. What is the structural difference between the two?

Read the given statements. (i) Fructose is the sweetest sugar. (ii) Glycine is the simplest amino acid. (iii) Lactose is a disaccharide composed of one molecule each of glucose and galactose. (iv) Cellulose is an unbranched chain of glucose molecules linked by beta-1 , 4-glycosidic bond. Which of the given statements are correct ?

If f:R rarr R and f(x)=g(x)+h(x) where g(x) is a polynominal and h(x) is a continuous and differentiable bounded function on both sides, then f(x) is one-one, we need to differentiate f(x). If f'(x) changes sign in domain of f, then f, if many-one else one-one. If f:R rarr R and f(x)=2ax +sin2x, then the set of values of a for which f(x) is one-one and onto is

If f:R rarr R and f(x)=g(x)+h(x) where g(x) is a polynominal and h(x) is a continuous and differentiable bounded function on both sides, then f(x) is one-one, we need to differentiate f(x). If f'(x) changes sign in domain of f, then f, if many-one else one-one. f:R rarr R and f(x)=(x(x^(4)+1)(x+1)+x^(4)+2)/(x^(2)+x+1) , then f(x) is

AB wire (length x) is vibrating in its fundamental mode. Wire AB is in resonance with resonance tube in which air column (length x/2) is also vibrating with its fundamental mode. Sound speed is 400 m/sec and linear mass density of AB wire is 10^-4 kg/m and g=10 m//sec^2 , value of mass m = [beta(10^-1)] kg , then find value of beta .Neglect the masses of wires in comparison to block's mass 'm'.

A circle of radius 1 unit touches the positive x-axis and the positive y-axis at A and B , respectively. A variable line passing through the origin intersects the circle at two points D and E . If the area of triangle D E B is maximum when the slope of the line is m , then find the value of m^(-2)

Glycogen is a branched chain polymer of alpha-D glucose units in which chain is formed by Cl-C4 glycosidic linkage where as branching occurs by the formation of C1-C6 glycosidic linkage. Structure of glycogen is similar to .... .
