🗑
Carbohydrates   -Carbon, Hydrogen and Oxygen -sugars and starches, with most made by plants.  
🗑
Isomers   Organic compounds with the same molecular formula but different structures.  
🗑
Monosaccharide   -Simple sugars  
🗑
Pentose sugars   5 Carbon sugars in Monosaccharides. Found in DNA and RNA.  
🗑
Hexose sugars   6 Carbon sugars in Monosacchardies. Found in Glucose and Fructose.  
🗑
Glucose   C6H12O6, blood sugar; made from carbs, proteins, and fats.  
🗑
Fructose   C6H12O6. Found in fruits and honey  
🗑
Galactose   C6H12O6. Monomer in milk sugar.  
🗑
Disaccharides   2 simple sugars chemically bound together by a dehydration/condensation reaction.  
🗑
Sucrose   Glucose and Fructose a.k.a table salt. Found in sugar cane and beats.  
🗑
Maltose   Glucose and Glucose a.k.a malt sugar. Found in fermented to make alcoholic beverages.  
🗑
Lactose   Glucose and Galactose a.k.a milk sugar.  
🗑
Polysaccharides   consists of many monomers chemically bonded together by a condensation reaction.  
🗑
Starch   Made by plants, using hundreds of units of Glucose. Used as a sweetener, preservative, and to add texture.  
🗑
Glycogen   "animal starch" and used a energy reserves  
🗑
Cellulose   Forms the outer layer of the cell walls in plants.  
🗑
Chitin   Forms the exoskeleton of insects and crustaceans and the cell wall of fungi.  
🗑
Lipids   Derivative of Hydrocarbons and contains COOH, found in the fatty acids.  
🗑
Neutral (simple) fats   a.k.a triglycerides, generally found in the diet and body.  
🗑
Saturated   has more Hydrogen, solid at room temperature, is from animal fats and has cholesterol.  
🗑
Unsaturated   has less Hydrogen, liquid at room temperature, is from plant oils and does not have cholesterol.  
🗑
Transfats   Hydrogenated oils processed to increase hydrogen double bonds without the kinks.  
🗑
Phospholipid   Second type of lipids, has a hydrophilic, and polar head and a hydrophobic, non-polar tail.  
🗑
Steroids   Soluable in benzene. Found in Testosterone, Estrogen and adrenal hormones, Vitamin D, Bile acids, and cholesterol.  
🗑
Proteins   have Carbon, Hydrogen, Oxygen and Nitrogen. Main component of tissues and body parts along with regulatory functions and neurotransmitters  
🗑
Amino Acids   Monomers of proteins that are small enough to enter the cell.  
🗑
Peptide Bonds   Joins amino acids together between COOH and NH2 groups.  
🗑
Primary Structures   "spells the protein" and consists on a number of polypeptide chains.  
🗑
Secondary Structures   3-dimensional structures  
🗑
Tertiary Structures   3-dimensional foldings that form a globular or spherical shape. EX, enzymes, blood proteins and anti-bodies.  
🗑
Quaternary Structures   Huge proteins with multiple globular proteins. EX, hemoglobin  
🗑
Nucleic Acids   DNA and RNA  
🗑
DNA   confined to the nucleus; forms the genes on the chromosomes. Small amounts are also found in organelles.  
🗑
RNA   Formed in the nucleus and enters the cytoplasm. Moves the ribosoms and directs protein synthesis.  
🗑
Monomers of Nucleic Acids   Guanine, Adenine, Cytosine, Thymine, and Uracil  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
