An unknown liquid collected from a sample of peas, is added to a beaker of water and is vigorously shaken. After few minutes, water and the unknown liquid made two separate layers. To which class of biomolecules, does the unknown liquid most likely belongs ?

Read the following statements below. I. All the carbon compounds that we get from living tissues can be called ‘biomolecules. II. The ash formed after burning a tissue contains inorganic and organic substances. . III. Beta amino acids are used by the cells to form proteins. . Identify the true and false statements.

Stereoisomerism occurs when the bond connectivity is same but the spatial arrangement of more than one type is possible. Stereoisomerism finds vast use in orgaic chemistry, mainly biochemistry as all the biomolecules, are generally stereospecific in their actions. Stereoisomerism in limited not only to organic compounds but also to inorganic compounds, mainly in co-ordination complexes. Stereoisomers include cis and trans isomers, chiral isomers, compound wilth different conformation of chelate rings and other isomers that differ only in the geometry of attachement of the metal ion. Select the incorrect statement:
