CHEMICAL TEXTURE SERVICES CHAPTER 20

Chemical Bonds that join amino acids together to form polypeptide chains are bonds.

Polypeptide chains are long chains of amino acids joined together by

• amino acids

• hydroxide bonds

• peptide chains

• peptide adhesive

What type of bond forms when the sulfur atoms in two adjacent protein chains are joined together?

• SODIUM

• CALCIUM

• HYDROGEN

• DISULFIDE

WHAT IS THE MAIN ACTIVE INGREDIENT IN TRUE ACID AND ACID-BALANCED WAVING LOTIONS?

• GLYCEROL MONOTHIOGLYCOLATE

• AMMONIUM THIOGLYCOLATE

• HYDROGEN PEROXIDE

• SODIUM HYDROXIDE

WHAT IS THE MAIN ACTIVE INGREDIENT OR REDUCING AGENT IN ALKALINE PERMS?

• GLYCEROL MONOTHIOGLYCOLATE

• AMMONIUM THIOGLYCOLATE

• HYDROGEN PEROXIDE

• SODIUM HYDROXIDE

THE ALKALINITY OF THE PERM CHOSEN SHOULD CORRESPOND TO THE RESISTANCE, STRENGTH,AND OF THE CUTICLE LAYER.

• TEXTURE

• SIZE

• ELASTICITY

• POROSITY

THE CHEMICAL ACTION OF BREAKS THE DISULFIDE BONDS THROUGH A CHEMICAL REACTION CALLED REDUCTION

• AMMONIA

• HYDROGEN PEROXIDE

• WAVING LOTION

• NEUTRALIZER

THE ACTION OF ALKALINE PERMANENT WAVING LOTION IS TO SOFTEN AND

• DISCOLOR THE HAIR

• SHRINK THE HAIR

• EXPAND THE HAIR

• CONDITION THE HAIR

Keratin Proteins are made of long chains of linked together end to end like beads.

• amino acids

• peptide bonds

• polypeptide chains

• cross links
