Maltose is made up of two a -D-glucose (in pyranose form) units held together by a (1 4) glycosidic bond. As there is a free aldehyde group at C-1 position of the second glucose molecule, maltose is known as reducing sugar. Maltose forms osazones. The enzyme that hydrolyses maltose is maltase. The ..

It is synthesised by heating a mixture of chloral (1 mol) with chlorobenzene (2 mol) in the presence of concentrated HSO 4..

Natural Cosine Tables - A part of the natural cosine tables is given below: Find from the tables the value of (i) cos 37 o (ii) cos 37 o 42 ' (iii) cos 37 o 45 ' (i) cos 37 o Find 37 o on the 'Natural Cosines' table in 'A' group. As there are no minutes, the value is read horizontally under the 0 '..

Natural Tangent Tables - An extract from the natural tangent tables is given below: From the tables find the value of (i) tan 51 o (ii) tan 51 o 18 ' (ii) tan 51 o 23 ' (i) tan 51 o Find angle 51 o on the 'Natural Tangent' table in 'A' group. As there are no minutes, tan 51 o = 1.235. Value is read..
