Hydrocarbons. Carbohydrates & Lipids. Amino acids & proteins. More amino acids & proteins. Nucleic acids, RNA & DNA. Single atoms of iron, copper, magnesium for some proteins.
Sweet to taste, polar, hydrophilic.
What are monosaccharides and disaccharides?
Structure that has no fatty acids and skeleton of four fused carbon rings.
What are steroids?
Protein molecules that assist in the proper folding of other proteins.
What is a chaperonin?

Polysaccharides that store energy. Present in plants and animals.
What are starches? What is glycogen?
Properties of lipids
What are properties that are non-polar, include long term energy storage, insulation, and protection?
Changes in temperature, pH or salt concentration may cause what to proteins.
What is denaturation?
High energy nucleotide that is a usable form of energy that cells use to do work.
What is ATP?
Draw a disaccharide: Sucrose, Lactose, OR Maltose.
Photo 3
Two structural polysaccharides.
What is Chitin and Cellulose?
Draw a fatty acid.
What includes a carboxyl group and a long hydrocarbon chain?
Write the differences between levels of protein structure.
What are:
Primary: the sequence of amino acids. Ultimately determines the shape of a protein.
Secondary: amino acid chain coils into a
helix or folds into pleated sheets. Due to hydrogen bonding between polar
groups of amino acid.
Tertiary: Overall three-dimensional shape of a polypeptide; usually globular shaped. Due to interactions between R groups.
Quaternary: Consists of two or more polypeptides linked.
The differences between RNA and DNA
DNA: Double strand, deoxyribose sugar, consists of genes for all proteins, bases include A, T, G, C
RNA: Single strand, copied from DNA, ribose sugar, used for protein synthesis, bases include A, U, G, C
Cellular respiration formula.
