NEET exams


Amino acids Acidic- Glu, Asp

Basic- Lys, Arg, His

Aromatic- Tyr, Trp, Phe

Saturated fatty acids Palmitic acid (16 C)

Stearic acid (18 C)

Unsaturated fatty acids Oleic acid (18:1)

Linoleic acid (18:2)

𝛼-Linolenic acid (18:3)

Arachidonic acid (20:4)

Phospholipids Diglycerides and a phosphate group attached to the third hydroxyl of glycerol.

Lecithin (Phosphatidylcholine)


Proteins Heteropolymer of 20 amino acids, linked by peptide bonds

Essential-9, nonessential-11

Nitrogenous base Purine base- Adenine, Guanine

Pyrimidine base- Thymine (DNA), Cytosine, Uracil (RNA)

Nucleosides Nitrogenous base + sugar

Ribose sugar in RNA

Deoxyribose sugar in DNA

Examples: Adenosine, guanosine, thymidine, cytidine, uridine

Nucleotides Nitrogenous base + sugar + phosphate

Adenylic acid, cytidylic acid, etc.

DNA and RNA Nucleotides linked with 3’-5’ phosphodiester linkage
The most abundant protein RuBisCO- Ribulose bisphosphate Carboxylase-Oxygenase
The most abundant protein in animals Collagen
Starch Polymer of glucose linked by 𝛼-1,4-glycosidic bond

Amylose and amylopectin

Glycogen Highly branched glucose polymer
Cellulose Linear polymer of glucose linked by β-1,4-glycosidic bonds.
Inulin Polymer of fructose
Chitin Polymer of N-acetylglucosamine
Ribozyme Catalytic RNA
Competitive inhibitor Inhibitor binds to enzyme due to structural similarity with the substrate

E.g. Malonate inhibits succinic dehydrogenase. Here substrate is succinate.

Hydrolases Facilitate hydrolysis of bonds such as glycosidic, peptide, ester, ether, etc.

E.g. amylase, lipase, nuclease, protease

Cofactors Non-protein part required for enzyme activity

Apoenzyme- Protein part of the enzyme

Prosthetic group Tightly bound to apoenzyme

E.g. haem group present in catalase, peroxidase

Coenzymes Bind to apoenzyme transiently


Metal ions as a cofactor Zn in carboxypeptidase
