Study Notes
Denaturation of Proteins
- Proteins can undergo denaturation, resulting in insoluble products, including:
- Proteans (insoluble products formed by water, dilute acids, and enzymes)
- Metaproteins (formed by the action of acids and alkalies on proteins)
- Coagulated proteins (insoluble products formed by heat or alcohol on natural proteins)
Classification of Proteins
- Based on function:
- Catalytic proteins (enzymes)
- Regulatory proteins (hormones)
- Protective proteins (antibodies)
- Storage proteins
- Transport proteins
- Toxic proteins
- Structural proteins
- Contractile proteins
- Secretary proteins
- Exotic proteins
- Based on size and shape:
- Globular proteins (water-soluble, fragile, and spherical in shape)
- Fibrous proteins (tough, water-insoluble, and fibrous in shape)
- Based on physiochemical properties:
- Simple proteins (yield only amino acids or their derivatives on hydrolysis)
- Conjugated proteins (attached to non-protein groups called prosthetic groups)
- Derived proteins (derived from simple and conjugated proteins)
Types of Proteins
- Simple Proteins:
- Albumins (soluble in water, dilute acids, and alkalies; coagulated by heat)
- Globulins (insoluble or sparingly soluble in water; coagulated by heat)
- Globins (colorless protein obtained by removal of heme from a conjugated protein)
- Prolamines
- Histones
- Protamines
- Albuminoids
- Glutelins
