Chapter 3, Problem 3.4CC
Summary Introduction
To determine: The similarities and differences between polysaccharides, proteins,
Introduction: Proteins and nucleic acids can be called informational macromolecules because they are involved in the transfer of genetic information from the nucleus to the cytoplasm for the formation of proteins. Polysaccharides can be considered as storage macromolecules and are composed of long-chains of sugars and their derivatives. Lipids constitute a heterogeneous category of cellular compounds that are hydrophobic in nature.

(b) What are the components?arrow_forwardSaturated fatty acids are called "saturated" because they are saturated with what component? C, H, or double bonds?arrow_forwardIn general, lipids (fats) are only slightly soluble in water due to the abundance of nonpolar features in their molecular structures. However, lipids also possess one or more hydroxyl groups (-OH) in their structures as well. What about this chemical feature would account for the slight solubility of some lipids in water?arrow_forward
- Lipoproteins are relatively large, spherical clumps of protein and lipid molecules that circulate in the blood of mammals. They are like suitcases that move cholesterol, fatty acid remnants, triglycerides, and phospholipids from one place to another in the body.
