Carbohydrates are naturally formed organic compounds from various plants. The common chemical formula, \(C _x\left( H _2 O \right)_y\), was considered as hydrates of carbon to derive the various carbohydrates. For instance, the general formula for glucose ( \(C _6 H _{12} O _6\) ) easily fits into the above formula. Carbohydrates also called saccharides are classified on the basis of their behavior towards hydrolysis. Monosaccharides cannot be hydrolyzed further to simpler units of polyhydroxy aldehyde or ketones. About 20 monosaccharides are known to occur in nature. Carbohydrates that yield large number of monosaccharide units are called polysaccharides. Amino acids contain ( \(- NH _2\) ) and ( - COOH ), which can be classified in various forms. Proteins are polymers of alpha amino acids which are connected to each other by a peptide bond or peptide linkage. When a native protein is subjected to physical change, its globules unfold and helix get uncoiled and the protein loses its biological activity. The protein is said to be denaturated.
During denaturation process of protein which structure(s) remain intact ?

Molar conductivity increases with......

(B) \(CH 3 CH 2 CH ( Br ) CH 3\)
(C) \(( CH 3) 3 CBr\)
(D) \(( CH 3) 2 CHCH 2 Br\)

The coordination compounds are of great importance. These compounds are widely present in the mineral, plants and animal world and are known to play many important functions in the area of analytical chemistry, metallurgy, biological systems, industry and medicine. For example, coordination compounds find use in many qualitative and quantitative chemical analysis. Some important metal extraction and purification make use of complex formation. Hardness of water can be estimated by stable complex formation of Ca\(^{2+}\) and Mg\(^{2+}\)
Impure nickel is converted to which of its complex to be decomposed to yield pure nickel?

For a linear programming problem, the feasible region is shown in the figure by shaded portion, then linear constraints are

Two parallel long wires carry currents, \( i_1 \) and \( i_2 \) with \( i_1 > i_2 \). When the currents are in same direction, the magnetic field at a point midway between them is \( 10 \mu \text{T} \). If the direction of \( i_2 \) is reversed, the field becomes \( 30 \mu \text{T} \). The ratio of \( i_1/i_2 \) is:

What will be the ratio of radii of two nuclei having their mass numbers in the ratio of 64:125?

Which one of the following seeds is an example of non-albuminous seed?

In RNAi, the genes are silenced by the formation of:
