pH scale |
- 0 acidic - 7 neutral - 14 alkaline/ base - acidic solution tend to have more hydrogen ions. - alkaline solution tend to have more hydroxide ions
|
|
|
Atom |
Composed of - protons / + / 1 - neutron / /1 - electrons / - / 0 |
|
|
Water |
Water is the most abundant inorganic substance in our body. - it's neutral |
|
|
6 Elements our body is composed of. |
- Na / sodium - K / potassium - Po / phosphorus - Cl / chloride - Ca / calcium - Mg / magesium |
|
|
6 Elements organic molecules are composed of. |
CHNOPS Carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur. All have C/H Most have N/O Some have P/S Carbons is the most common element. All are Carbon base. |
|
|
2 main chemical reaction in the body |
Catabolism - take complex and make simple molecules by adding water - also called hydrolysis or decomposition Anabolism - take simple and make complex and water is removed - also called dehydration. Exp carbs to glucose. |

|
5 organic molecules |
Proteins Carbs Lipids/fats Nucleic acid ATP |
|
|
Carbohydrates |
Consist of - sugars, starches, glycogen, cellulose. Most end in "____ose". Ribose, fructose, glucose, glycogen is exception. Carbs are made of carbon, hydrogen, oxygen in 1:2:1 ratio. C5 H10 O5- pentose found in RND / DNA C6 H10 O6- hexos which give us energy. Glucose, fructose, galactose - most common are most complex. Most commonPolysaccharides are glycogen. -consist of 100+ glucose molecules. Joined anabolic. |
|
|
Lipids/fats |
-Consist of C/H/O but not in 1:2:1 ratio due to less oxygen. -fats are hydrophobic, don't dissolve in water. -do dissolve in alcohol, mineral spirit, chloroform, either and xylene. -fats have twice the energy of carbs. -3 types of fats. -triglyceride - fatty acids/ glycerol Phospholipids - cell membrane Steroids - sex hormones. Testosterone / estrogen
