Which is a true statement comparing phospholipids and triglycerides (fats and oils)? A) Both molecules contain a phosphate group. B) Triglycerides may be saturated or unsaturated, but all phospholipids are saturated. C) Phospholipids are the primary storage form for fats in our bodies. D) Phospholipids occur in fused rings, whilst triglycerides maintain a straight-chain form. E) Phospholipid molecules have a distinctly polar 'head' and a distinctly non-polar 'tail,' whilst triglycerides are predominantly non-polar.Explanation / Answer
17. For the reaction, steady-state assumption
Correct option:
Explanation: The basic assumption for a chemical reaction to be in steady state is that the rate of forward reaction should be equal to the backward reaction.
18. Which is a true statement comparing phospholipids and triglycerides (fats and oils)?
Correct option:
Explanation: phospholipids is a type of lipid mainly found in the cell membrane. It is made up of two fatty acid tails and a phosphate group head, both of them are joined with help of glycerol molecule. The phosphate group is hydrophilic and the tail is hydrophobic in nature. Whereas triglycerides consist of two or more different fatty acids which are linked by ester bond rendering non-polar, hydrophobic and insoluble properties in them.
