Answer:
E) A, B, and C
Explanation:
A chemist would call them condensation reactions, that is, reactions in which two molecules combine by splitting out a molecule of water.
A) Triacylglycerides form by splitting out molecules of water from glycerol and fatty acids
C₃H₅(OH)₃ + 3RCOOH ⟶ C₃H₅(OCOR)₃ + 3H₂O
glycerol fatty acid triacylglyceride water
B) Carbohydrates form by splitting out molecules of water from simpler carbohydrates
C₆H₁₂O₆ + C₆H₁₂O₆ ⟶ C₁₂H₂₂O₁₁ + H₂O
glucose fructose sucrose water
C) Proteins form by reactions between amino acids.
H₂NCH(R)CO-OH + H-NHCH(R)COOH
amino acid amino acid
⟶ H₂NCH(R)CO-NHCH(R)COOH + H₂O
dipeptide water
Dehydration reactions are used in forming - option E. A triacylglycerides, B polysaccharides, C proteins.
Dehydration reaction where two hydrogen atoms from one molecule combine with an oxygen atom on the other molecule or hydroxyl group from one molecule combine with a hydrogen atom from the other molecule in both cases, water is released as a product.
A) Triacylglycerides -
splitting out molecules of water from glycerol and fatty acids
C₃H₅(OH)₃ + 3RCOOH ⟶ C₃H₅(OCOR)₃ + 3H₂O
glycerol fatty acid triacylglyceride water
B) Carbohydrates or polysaccharides: monomers like glucose from polymers.
C₆H₁₂O₆ + C₆H₁₂O₆ ⟶ C₁₂H₂₂O₁₁ + H₂O
glucose fructose sucrose water
C) Proteins: form by reactions between amino acids.
H₂NCH(R)CO-OH + H-NHCH(R)COOH
amino acid amino acid
⟶ H₂NCH(R)CO-NHCH(R)COOH + H₂O
dipeptide water
Thus, the Dehydration reactions are used in forming - option E. A triacylglycerides, B polysaccharides, C proteins.
