What vitamin does not travel through the bloodstream in the form of a lipid micelle? Vitamin C Which lipid has a 4-ring structure? Sterol Which of the following situations is MOST likely to increase the rate of beta oxidation? fasting A patient who is on a no-fat diet is at particular risk of deficiency in: Vitamin A During starvation, triglycerides can help supply some of the body's glucose needs.

BCH 462 Exam 4 Questions With 100% Correct Answers Fatty Acid Synthesis - answerFatty acids are built in several passes, processing one acetate unit at a time. The acetate is coming from activated malonate in the form of malonyl-CoA. Each pass involves reduction of a carbonyl carbon to a methylene carbon. Overall, repeating four-step sequence that elongates the fatty acyl chain by two carbons at each step, uses NADPH as the electron donor. Two enzyme-bound -SH groups serve as activating...

Which of the following lipoproteins distributes dietary lipids? chylomicron The interaction of chylomicrons with lipoprotein lipase is stimulated by which of the following Apo proteins? ApoC II Nascent chylomicrons are synthesized in which tissue? Intestine Bile salts are synthesized from cholesterol and are used for the emulsification of dietary lipids. What is the primary fate of bile salts during digestion? They are reabsorbed in the ileum Nascent chylomicrons ...

A 3-year-old male is brought to the emergency department by his parents. He is unconscious on admittance and his blood glucose was 15 mg/dl, ( normal 75 - 105 mg/dl).
