Importance of Chemicals in Food
Importance of Chemicals in Food - Actually speaking, natural food substances are various forms of chemicals. For e.g., rice is a carbohydrate. Fruits contain carbohydrates and acids like citric acid. Vegetables contain proteins (amino acid blocks) a..
Ribosomes
fig. 22.4 Ultrastructure of a Ribosome A ribosome has two binding sites for tRNA molecules. One is called A site (acceptor or aminoacyl) and the other is termed P site (peptidyl). These sites span across the larger and smaller subunits of the ribosome. The A site receives the tRNA amino h..
Formation of Simple Organic Compounds
As the earth cooled further, the primitive inorganic molecules interacted and combined with one another to form simple organic compounds. Simple sugars, fatty acids, glycerol, amino acids and nitrogen bases (purines and pyrimidines) were probably the simple o..
Amides
Amides contain more nitrogen than amino acids and form the structural part of most proteins. The two important amides found in plants are asparagine and glutamine. They are formed from two amino acids namely glutamic acid and asp..
Modification of Released Polypeptide
The just released polypeptide is a straight, linear exhibiting a primary molecule, structure. It may lose some amino acids from the end with the help of a peptidase enzyme, and then coil and fold on itself to acquire secondary and tertiary structure. It may even combine with oth..
Molecular Mechanism of Hormone Action
How does the neuroendocrine control work? The hormones are released in very small quantities, yet they can cause widespread dresponses in cells or tissues all over the body. These responses in cells or tissues all over the body. These responses can be quite specific and selective in different cell..
Leading Strand
The enzyme forms one new strand in a continuous stretch in the 5'-3' direction and is called leading strand. On the other parent strand, the enzyme forms short stretches of DNA once again in the 5'-3' direction starting from an RNA primer. These short DNA fra..

Nylon-6 is prepared from the monomer caprolactum which is obtained from cyclohexane (petrochemical). Since caprolactum is more easily available, it is used for polymerization which is carried out in the presence of water that first hydrolyses the caprolactum to amino acid. Subs..

Alkanamines (Amines) - Amines are formed by replacing one or more hydrogen atoms of ammonia (NH 3 ) with alkyl groups. These are further classified as primary, secondary and tertiary amines according to one, two or three hydrogen atoms of ammonia being replaced by alkyl groups. For exampl..
