Study Notes
Types of Proteins
- Fibrous proteins are insoluble in water and provide structural support.
- Examples of fibrous proteins include collagen and elastin.
- Globular proteins are partly soluble in water, with functions primarily not related to structure.
- Enzymes are common examples of globular proteins.
- Fibrous proteins exhibit a long, rod-shaped 3D structure.
- Globular proteins have a compact, ball-like shape with irregular surfaces.
Fatty Alcohols
- Glycerol is a trihydric alcohol, possessing three hydroxyl (OH) groups.
- Glycerol is also known as glycerine.
- It is synthesized from glucose in the body.
- Glycerol can form esters with fatty acids, important in lipid formation.
- It serves nutritional functions by being converted into glucose and phospholipids.
- Sphingosine is a monohydric alcohol, containing one hydroxyl group.
- It plays a role in the structure of sphingolipids.
- Sphingosine is synthesized from serine and palmitic acid.
Mono and Polysaccharides
- Monosaccharides are colorless and consist of a single sugar unit.
- Polysaccharides are white and made up of multiple sugar units.
