etertiary structure D-quaternary structure 18) Carbohydrates and proteins are built up from their basic building blocks by the A) addition of a water molecule between each two units B) addition of a carbon atom between each two units C) removal of a water molecule between each two units D) removal of a carbon atom between each two units 19) Which statement about enzymes is FALSE? A) Enzymes require contact with substrate in order to assume their active form. B) Most enzymes can catalyze millions of reactions per minute. C) Enzymes may use coenzymes derived from vitamins or cofactors from metallic elements D) Enzymes may be damaged by high temperature we rueExplanation / Answer
18. The answer is C. Removal of a water molecule between each two units.
When coming to carbohydrates, the removal of water during Dimarization leads to the formation of glycosidic bond.
Eg. Sucrose is a disaccharide and it is composed with glucose and fructose. These glucose and fructose is linked with (12) glycosidic linkage.
C6H12O6 + C6H12O6 >>>>>>>> C12422O11 + H2O
When coming to peptides, the removal of water during Dimarization leads to the formation of peptide bond.
The between one amino acid of COOH and another amino acids of NH2 group is called peptide bond. This peptide bonds is also called as CO-NH bond too...
