Difference between a dehydration reaction and a hydrolysis reaction

Dehydration: occurs when a hydrixyl group and hydrogen group is removed

• used in synthesis reactions to form macromolecules

Hydrolysis: insertion of the components of water to break a bond between two molecules

Difference between ph of 5 and ph of 8

oh of 5 is 1000x more acidic than ph of 8c

water being cohesive vs adhesive

cohesive = stick to other water molecules

adhesive = stick to other surfaces

difference in structure vssimple carbohhydrate bs complex carbohydrate

Simple carbs contain low numbers of carbon atoms (3-7)

complex carbs contain high number of atoms in chains of sugar units

Why can some complex carbohydrates be used for energy and why others cannot

Human digestive tract produces enzymes that can digest tyoes if kub=nkages between some forms of sugar, but not all (cellulose)
