100% PASS
Polysaccharides are
carbohydrate polymers that are formed by dehydration synthesis that attaches many
monosaccharides together. Ex) starch, glycogen, cellulose, heparin, and peptidoglycan
Saccharides are
sugars and carbohydrates
Disaccharides are
sucrose, lactose, maltose (double sugars)
Monosaccharides
glucose, fructose, galactose simple suagrs
1. Tri=3 pent=5 hex=6 EX) ribose is a 5 carbon sugar so its a Pentose, glucose is a 6 carbon
sugar so its a hexose
Hydroxide group also called alcohol
an O-H single bonded; helps dissolve organic compounds
Aldehyde
,An organic molecule with a carbonyl group located at the end of the carbon skeleton.
ketones
R-CO-R
starches and cellulose
Is a glucose polymer that has glycosidic bonds that cannot be broken down by human digestion
Structure of a DNA nucleotide
sugar molecule(deoxyribose) , phosphate group, nitrogenous base
Stricture of a RNA molecule
Sugar molecule (ribose) , phosphate group, and nitrogen base
Lipids
Energy-rich organic compounds, such as fats, oils, and waxes, that are made of carbon,
hydrogen, and oxygen. They can be stored in the form of Triglycerides in fat cells, cholesterol,
steroids, hormones, cell signaling and immune mending in form of prostaglandin
Triglycerides
an energy-rich compound made up of a single molecule of glycerol and three molecules of fatty
acid. They are hydrolyzed in the small intestine by enzyme lipase to monoglycerides and fatty
acids
, Lipoproteins
Protein-and-lipid substances fatty acids and cholesterol are transferred from lipoproteins
complex's in the bloodstreams intro cells where they serve as raw materials for a construction of
cell membranes, as a source of energy, production, and many other functions
1. HDL = high density (lowers the risk of heart disease)
2. LDL low density (high LDL and triglyceride increases risk heart diseases)
Cholesterol
Four ring lipid based molecule and as important component of the cell membrane and a
precursor molecule for the synthesis of the steroid hormones, testosterone, and estrogen and
precursor for vitamin D ( most is synthesized)
Amino acids are
building blocks of proteins they have a central carbon atom single bonded to a hydrogen Atom
and three functional groups (R group)
Amino Acid: Serine
Contains hydroxyl group in the side chain (-OH)
amino acids and alanine,
Hydrocarbons CH3,
The amino acid lysine
Amine group (NH2)
