Carbohydrates,Proteins,Lipids Nucleic Acids
Proteins buliding block?
Amino Acids 20 different amino acids
Amino Acids
Are chained into a polymer Each amino acid is different some "like" water dissolve in it Some "fear" water & separate from it
Carbohydrates
Building block molecules=sugars
Carbohydartes elements
C,H,O
Lipids elements
C,H,O
Nucleic Acids Elements
C,H,O,N and P(phosphorous)
Proteins elements
C,H,O,N plus sometimes Sulfur
Lipids
Concentrated energy molecule
Water Loving Amino Acids
Hydrophillic try to stay in water in cell
Water Fearing Amino Acids
Hydrophobic try to get away from water in the cell
Nucleic Acids
Inforamation Molecule include DNA and RNA
Perodic Table of Elements
Shows the atomic numbers and shows the mass
Lipids functions
enery storage very concentrated twice the energy as carbohydrates celll membrane insultes the body cushions the organs
Nucleic Acid Functions
genetic material stores information genes blueprint for building protenis transfers inforamtion
Types of sugars
glucose fructose sucrose maltose
Cholesterol
good molecule in cell membranes makes hormones from it too much cholesterol can be bad
Properties of Water
ice is less dense than liquid water Good solvent-dissolves charged plus polar molecules high heat of vaporization
Water
is a polar due to its unequal distribution of electrons
Saturated fats
most animal fats solid at room temperature contributes to heart disease
Proteins
multipurpose molecules
Proteins Functions
normones signals from one body system to another insulin movement muscle immmune system protect against germs enzymes help chemical reactions
Unsaturated fats
plant,vegetables,fruits liquid at room temperature better for you than saturated fats
Functions of Carbohydrates
quick energy energy storage structure
Nucleotides
there are 5 different nucleotides and different nitrogen bases A,T,C,G,U
