Important Concepts of Biomolecules for JEE Main

1. Amino Acid Structure: The general structure of an amino acid is given by: 

$R\text{-}CH(NH_2)\text{-}COOH$

2. Peptide Bond Formation: The formation of a peptide bond between two amino acids is a condensation reaction, and the resulting dipeptide can be represented as: 

$\text{NH}_2\text{-}CH(R_1)\text{-}COOH + \text{NH}_2\text{-}CH(R_2)\text{-}COOH \rightarrow \text{NH}_2\text{-}CH(R_1)\text{-}CO\text{-}NH\text{-}CH(R_2)\text{-}COOH + \text{H}_2O$

3. Nucleotide Structure: The structure of a nucleotide includes a phosphate group, a pentose sugar (ribose or deoxyribose), and a nitrogenous base. It can be represented as: 

$\text{5' - P - (sugar) - (base) - 3'}$

4. DNA Double Helix Structure: The double helix structure of DNA is represented by the Watson-Crick model, where adenine (A) pairs with thymine (T) and guanine (G) pairs with cytosine (C). The equation is: 

$A=T, \quad G\equiv C$

5. Monosaccharide Structure: The general structure of a monosaccharide is given by: 

$(CH_2O)_n$

6. Henderson-Hasselbalch Equation: For calculating the pH of a buffer solution, the Henderson-Hasselbalch equation is used:

$\text{pH} = \text{pKa} + \log\left(\frac{\text{[A^-]}}{\text{[HA]}}\right)$

7. Michaelis-Menten Equation: Describing enzyme kinetics, the Michaelis-Menten equation is: 

$V_0 = \frac{{V_{\text{max}} \cdot [\text{S}]}}{{K_m + [\text{S}]}}$
