Draw the two amino acids serine and alanine, and a dipeptide that could be formed by combining these two amino acids (ala-ser). Draw these molecules at a pH=7. In peptide nomenclature the amino terminus is on the left and the carboxyl terminus is on the right. 1. How many waters were released by formation of this dipeptide from individual amino acids? two 2. How many hydrogen bond donors does your dipeptide have? 2 3. If you were to draw this dipeptide at a pH = 1, would the number of hydrogen bond donors change? yes, the number of H-bond
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
