Dehydration reactions assemble polymers, and hydrolysis reactions break down polymers. Which of the following is an example of a hydrolysis reaction? the reaction of a fat, forming glycerol and fatty acids with the consumption of water. Which of the following statements concerning saturated fats is true? They are generally solids at room temperature. A molecule with the formula C18H36O2 is probably a: fatty acid Hydrogenated vegetable oil is the primary ingredient in margarine. How does hydrogenated vegetable oil differ from nonhydrogenated vegetable oil? Hydrogenated vegetable oil is a solid at room temperature, whereas nonhydrogenated vegetable oil is a liquid. Which of the following large biological molecules will self-assemble into a bilayer when mixed with water? phospholipids There are 20 different amino acids. What makes one amino acid different from another? different side chains (R groups) attached to the alpha carbon How many peptide bonds are present in a polypeptide that contains 45 amino acids? 44 Which type of interaction stabilizes the alpha helix and the beta pleated sheet structures in proteins? hydrogen bonds Changing a single amino acid in protein consisting of 433 amino acids would: always alter the primary structure of the protein and sometimes alter its tertiary structure or function. How will brief heating (to 95 degrees C) affect macromolecular structures in aqueous solution? Proteins will unfold (denature.) A nucleotide is composed of: a nitrogenous, base, a phosphate group, and a pentose sugar. If a DNA sample were composed of 15% adenine, what would be the percentage of thymine? 15 Approximately 32 different monomeric carbohydrate subunits are found in various natural polysaccharides. Proteins are composed of 20 different amino acids. DNA and RNA are each synthesized from four nucleotides. Which class of biological polymer has the greatest functional variety? proteins A nutritional supplement developed for athletes is shown to contain only carbon, hydrogen, and oxygen. Based on these data, you may safely conclude that: the food may contain carbohydrates and lipids, but not protein. A food company wishes to convert corn oil into a spread that is solid at room temperature.

Hydrolysis also helps in breaking down proteins, fats, and complex carbohydrates in food.
What is A hydrolysis reaction quizlet?hydrolysis. A chemical reaction in which a compound is broken down into smaller molecules by reacting with water. In biology most hydrolysis reactions involve polymers breaking down into monomers.
What is true about A hydrolysis reaction?Hydrolysis reactions use water to breakdown polymers into monomers and is the opposite of dehydration synthesis, which forms water when synthesizing a polymer from monomers. Hydrolysis reactions break bonds and release energy.
Which best describes A hydrolysis reaction?Which best describes a hydrolysis reaction? A. Molecules are broken down into smaller ones by breaking covalent bonds within water molecules and transferring hydrogen atoms and hydroxyl groups to the smaller ones.
