Study Notes
Organic Compounds
- Contain carbon and hydrogen and a simple C-H bond
- Arranged in rings or chains
- Chemically large, complex and high in energy
- Examples: methane (CH4), glucose (C6H12O6)
Inorganic Compounds
- Do not contain carbon and hydrogen, lack of C-H bond
- Mostly simple (low in energy) and chemically small
- Obtained from natural processes.
- Examples: NaCl, H2O
- Water comprises 75-85% of body weight
- Water is a universal solvent
- Oxygen is 21% of the atmosphere
- Oxygen is utilized by animals during respiration
Organic Certification
- Crops not treated with pesticides, petroleum-based fertilizers or sewage sludge
- Animals (cows, pigs, and chickens) are not treated with growth hormones or antibiotics
- Animals are exposed outdoors in order to be able to eat organic food
- Genetically engineered or treated with ionizing radiation food is not FDA approved
OCCP (The Organic Certification Center of the Philippines)
- Conducts training on organic farming and organic certification
- Has 4 Major Categories:
- Carbohydrates
- Lipids
- Nucleic Acids
- Proteins
Carbohydrates
- Principal source of energy
- Provide shape to certain cells
- Components of many antibiotics and coenzymes
- Essential part of DNA
Types of Carbohydrates
-
Monosaccharide (Simple Sugar)
- 5-C sugar: ribose in RNA, deoxyribose in DNA
- 6-C sugar: C6H12O6
- Glucose, Fructose, Galactose (Isomers)
- Fructose: simple sugar found in fruits
- Glucose - blood sugar in the blood
- Galactose: simple sugar found in milk
-
Disaccharide (Combination of 2 Simple Sugars)
- Sucrose: reg.table sugar made from sugarcane sap & sugar beet root (glucose + fructose)
- Lactose: or milk sugar (glucose + galactose)
- Maltose: or grain sugar made from grains such as barley, rice or wheat (glucose + glucose)
-
Polysaccharide (Complex Sugar)
- Starch: also known as Amylose is the stored form of glucose in plants
- Animals store glucose as Glycogen in the liver & muscles
- Cellulose
- Humans cannot digest
- Source of FIBER (e.g.VEGETABLES like broccoli, asparagus etc.)
- Ruminants can digest CELLULOSE
- Chitin
- Exoskeleton of insects, spiders & crustaceans
- Supports cells, resembles a glucose polymer except that it contains nitrogen atoms
- Used in manufacture of surgical thread because it is tough, flexible & biodegradable
Lipids
- Do not dissolve in water but can be dissolved in non-polar solvents
- Hydrophobic, contain long chains of non-polar carbon-carbon and carbon-hydrogen bonds
- Can be synthesized from carbohydrates in cells
- Store more energy (9 food calories or 37 kJ of energy per gram)
- Provide cushioning for vital organs and insulation
- Play important roles in plasma membrane structure and serve as precursors for important reproductive hormones
Saturated Fats
- More C-H bonds means more energy or calories
- Solid at room temperature
- Sources of energy
- Come from animal fats such as bacon fat and butter.
- May increase the risk of cardiovascular diseases such as atherosclerosis
Unsaturated Fats
- Double bond between carbon atoms and fewer hydrogen bonds
- Liquid in room temperature
- Come from plants such as corn oil and olive oil
- Healthier than saturated counterparts
Trans Fat
- Vegetable oils which are made of unsaturated fats turned into solid fats
- Unsaturated fats whose fatty acid tails are straight
- Done by attaching hydrogen atoms onto the carbons that makes it look & taste like saturated fat.
- Called hydrogenated vegetable oil or trans fat
Types of Lipids
- Triglyceride
- Known as fat molecule
- Consists of 3 long hydrocarbon chains with 1 glycerol molecule
