Term
Chemicals known as "alcohols" contain this group
Definition
Hydroxyl Group
Term
Polar. Dissolves in water.
Definition
Hydroxyl, Carbonyl, Carboxyl, Amino, Phosphate Groups, (Sulfhydryl - slightly)
Term
The names of chemicals with this group typically end in -ol.
Definition
Hydroxyl group
Term
This addition of this group makes a chemical acidic.
Definition
Carboxyl group - carboxylic or organic acids (NOTE: A phosphate group is also sometimes considered to be an acidic group)
Term
The addition of this group makes a chemical basic.
Definition
Amino group (Amines)
Term
Two of these groups can react to form a "cross-link" that stabilizes a protein
Definition
Sulfhydryl group
Term
Chemicals known as "thiols" have this group
Definition
Sulfhydryl group
Term
These groups are found in each amino acid.
Definition
Carboxyl and Amino
Term
Molecules with this functional group are given a negative charge of 2- (1- if the group is within the molecule)
Definition
Phosphate group
Term
There are three of these lined up in the molecule that the body uses as its energy "currency"
Definition
Phosphate groups (ATP)
Term
The addition of this group to DNA affects the expression of genes.
Definition
Methyl group
Term
This group is an oxygen and hydrogen bonded together.
Definition
Hydroxyl group
Term
This group is a carbon double bonded to an oxygen
Definition
Carbonyl group
Term
This group is a carbon double bonded to one oxygen and single bonded to another which is bonded to a hydrogen
Definition
Carboxyl group
Term
This group is a nitrogen bonded to two (or three) hydrogen atoms)
Definition
Amino group
Term
This group is a sulfur bonded to a hydrogen
Definition
Sulfhydryl group
Term
This group is a phosphorus atom bonded to four oxygen molecules (one of them double bonded)
Definition
Phosphate group
Term
This group is a carbon bonded to three hydrogen atoms
