Carbonyl: polar, ketone/aldehyde, >C=O
Carboxyl: polar, acts as an acid, carboxylic acid/organic acid, --COOH
--SH
what is sulfhydryl
hydrogen bonds are formed between what kinds of molecules
what are 2 polar/positive and negative molecules
breaks the bond of two monomers by adding a water molecule
what is hydrolysis

what is phosphodiester
where is the methyl group in R--CH3
What is --CH3
structure of an amino acid
what is amino group, R group, carboxyl group
Name the properties of water (8)
what is high specific heat, high heat of vaporization, universal solvent, evaporative cooling, surface tension, cohesion, adhesion, capillary action
creates a bond between two monomers by releasing a water molecule
what is dehydration synthesis
saturated vs unsaturated fat bonds
saturated: single bond between carbon atoms, solid at room temperature, straight, ex. butter
unsaturated: at least 1 double bond, bent tail, liquid at room temperature, ex. olive oil
phosphate chemical group
what is --OPO32
what would happen if a polar R molecule got switched out for a nonpolar R molecule
The molecule would fold in and no longer be compatible with the signal molecule/the function would change
