Answer

Brief Explanations:

  1. When joining a fatty acid to glycerol, a water molecule ($H_2O$) is removed through a dehydration - synthesis reaction.
  2. A triglyceride is a lipid molecule composed of glycerol and three fatty acid chains.
  3. Glycine has the structure $NH_2 - CH_2 - COOH$.
  4. Alanine has the structure $NH_2 - CH(CH_3)-COOH$.
  5. To join glycine and alanine to form a dipeptide, a peptide bond is formed between the amino group of one and the carboxyl group of the other through a dehydration - synthesis reaction.
  6. To join two amino acids, a water molecule ($H_2O$) is removed as a by - product of the peptide bond formation.

Answer:

  1. A water molecule ($H_2O$)
  2. A lipid molecule composed of glycerol and three fatty acid chains
  3. $NH_2 - CH_2 - COOH$
  4. $NH_2 - CH(CH_3)-COOH$
  5. Form a peptide bond through dehydration - synthesis
  6. A water molecule ($H_2O$)
