PRESENTATION OUTLINE
CARBOHYDRATE
- A carbohydrate is any large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose.
Chemical composition of Carbohydrate
FUNCTION OF CARBOHYDRATE
- Providing energy and regulation of blood glucose
- Sparing the use of proteins for energy
- Breakdown of fatty acids and preventing
- ketosis
- Biological recognition processes
- Flavor and Sweeteners
Dietary fiber
There are monosscharides and polysaccharides.
- There are monosscharides and polysaccharides
LIPID
- Any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble inorganic solvents.
CHEMICAL COMPOSITION OF LIPID
FUNCTION OF LIPIDS
- Long term energy storage
- Protection against heat loss
- Protection against water loss
- Protection against physical shock
- Chemical messengers
- Major component of membrane phospholipids
EXAMPLES OF LIPIDS
- Soaps and detergents
- Waxes
- Phospholipids
- Steroids
- Butter and oil
PROTEINS
- any of a class of nitrogenous organic compounds that consist of large molecules composed of one or more long chains of amino acids
CHEMICAL COMPOSITION OF PROTEINS
FUNCTIONS OF PROTEINS
- Storage
- Transport
- Regulatory
- Movement
- Structural
- Enzymes
EXAMPLE OF PROTEINS
Amino acids; such as hair, muscles, and skin. Meat and nuts are also proteins.
Polypeptides; such as enzymes, hemoglobin, and myoglobin.
NUCLEIC ACIDS
- A complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.
CHEMICAL COMPOSITION OF NUCLEIC ACIDS
FUNCTION OF NUCLEIC ACIDS
- The main functions is store and transfer genetic information.
- Use the genetic information to direct the synthesis of new protein.
- The deoxyribonucleic acid is the storage place for genetic information in the cell.
Some examples of nucleic acids are DNA, RNA and also nucleotides.
