ikadub [295]

Answer:

The given statements have been rearranged in the following order to depict the flow of events that account for lipid digestion in the human body:

  1. Mechanical digestion by chewing breaks food down.
  2. During digestion, gastric lipases break down fat into fatty acids and triglyceride molecules.
  3. Gastric lipase digests some triglycerides.
  4. The pancreas secretes gastric lipase into the small intestine, where the majority of fat digestion occurs.
  5. Lipid ­digesting enzymes from the pancreas break down the triglycerides into two free fatty acids and a monoglyceride.
  6. Lingual lipase is secreted from the pancreas and breaks down triglycerides.
  7. With the aid of pancreatic lipase, fats are further broken down into free fatty acids and monoglycerides.
  8. Products of fat digestion are packaged into micelles and transported to the enterocytes.

The process is started in the mouth. Action of the teeth physically breaks down the food and increases it surface area that allows for better access to it for the enzymes to carry out mechanical digestion. Gastric lipases are those in the stomach, most of the lipid digestion takes place in the small intestine with the help of enzymes secreted by the pancreas and the small intestine itself. After digestion, the final products are taken up by the lymphatic system.

Hope that answers the question, have a great day!

maxonik [38]

Answer:

The purine ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the pyrimidine bases are synthesized separately and then coupled to ribose-5-phosphate via the C-N glycosidic bond.

Explanation:

In the de novo synthesis of nucleotides, their metabolic precursors such as aminoacids, ribose-5-phosphate, CO₂ and NH₃ are used as starting materials.

In purine  nucleotide synthesis, the ring structure is built up on ribose-5-phosphate of PRPP by addition of one or a few atoms one at a time starting with the amino group donated by glutamine until the first intermediate inosinate is synthesized.

In pyrimidine ring synthesis, orotate is first synthesized from carbamoyl phosphate and aspartate, and then is attached to ribose-5-phosphate of PRPP, before it is then converted to the common pyrimidine nucleotides starting from uridylate.
