What types of functional groups are present in an amino acid? A carbohydrate?

Answer 1

An amino acid contains a carboxyl group and an amine group and other groups, depending on its structure.

A carbohydrate contains hydroxyl groups and several other functional groups depending on the structure.

A typical amino acid has the formula

The green NH₂ group is an amino group. The COOH is the carboxyl group.

In addition the R side chain may contain other functional groups such as -SH (sulfhydryl) and -S-S- disulfide).

Glucose and fructose are typical carbohydrates.

They both contain hydroxyl groups, but glucose has an aldehyde group while fructose has a ketone group.

The cyclic forms contain hemiacetal, hemiketal, acetal, and ketal groups.

The cyclic form of glucose has a hemiacetal group at C-1, and fructose has a hemiketal group at C-2.

In lactose, the 1,4-linkage between galactose and glucose is an acetal group.

In sucrose, the 1,2-link between glucose and fructose is an acetal on the glucose side and a ketal on the fructose side.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
