1 Pepsin

2 Cellulose

3 Ptyalin

4 Lipase

BIOMOLECULES

1 Lactose contains

α -

glycosidic linkage between

C_{1}

of galactose and

C_{4}

of glucose.

2 Lactose

(C_{11} H_{22} O_{11})

is a disaccharide and it contains

8

hydroxyl groups.

3 On acid hydrolysis, lactose gives one molecule of

D (+) - g l u

cose and one molecule of

D (+)

-

galactose.

4 Lactose is a reducing sugar and it gives Fehling's test.

BIOMOLECULES

31256 Leucine amino acids is the

1 Essential

2 Non-essential

3 Aromatic

4 Basic

Explanation:

Leucine is an essential amino acid for protein synthesis. Additionally, similarly to other amino acids, the carbon skeleton of leucine can be used to generate $A T P$ .
