Study Notes
Amino Acids and Proteins
- Proteins that contain all essential amino acids are termed complete proteins.
- The conversion of amino acids into other forms occurs primarily in the liver.
- The human body requires nine essential amino acids during adult life.
Essential and Non-Essential Amino Acids
- Non-essential amino acids are those that the body can synthesize and are not required in the diet.
- Two essential amino acids needed only during infancy are histidine and arginine.
Functions of Proteins
- Proteins play a crucial role in building and repairing tissues, forming enzymes, hormones, and other body chemicals.
- The quality of a diet can be improved by combining different protein sources to provide all essential amino acids.
Dietary Combinations
- A common food combination that enhances diet quality includes legumes and grains.
Functions of Specific Proteins
- The main function of haemoglobin is to transport oxygen in the bloodstream.
- Collagen is identified as a key protein in connective tissue.
Properties of Proteins
- Wheat flour is suitable for making bread or chapati due to its gluten content, which provides elasticity.
- The carboxyl group of an amino acid exhibits acidic properties.
Protein Classifications
- Conjugated proteins are formed when simple proteins combine with non-protein substances.
- Simple proteins are composed mainly or solely of amino acids without any non-protein components.
- Proteins that are easy to digest and contain essential amino acids are often referred to as high-quality proteins.
- The products of digestion of simple conjugated proteins are known as peptides.
- In classification, haemoglobin belongs to the category of globular proteins.
