**Question:**What do most amino acids have in common with most monosaccharides?**Options:**- Both contain ionizable groups that lack pKa values. - Both non-enzymatically attach themselves to nucleic acids. - Both are transported by albumin within the blood. - Both exist as isomers, due to differences in stereochemistry. **Explanation:**This question is exploring the similarities between amino acids and monosaccharides. Each option lists a characteristic that could potentially be shared by both molecules. The correct answer would be the characteristic that is true for both amino acids and monosaccharides. A key concept is the presence of isomers due to differences in stereochemistry, as both amino acids and monosaccharides can form different isomers.

Amino acids are the building blocks of proteins. There are 20 major proteogenic amino acids that…

The ideal buffer range for any amino acids is pH above or below its pI values because the amino acid will get get precipitated at its pI. pKa1 of -COOH group of Cys = 1.71 pKa2 of -NH2 group of Cys = 10.78 pKa3 of side chain group of Cys = 8.33 (it indicates that the thiol group of Cys is a strong acid than the -NH2 group pf Cys as pKa Cys side chain is lower). Thiol side chain of Cys will loose proton first than -NH2. Net charge on Cys is zero in structure B, i.e. Structure B is a zwitterion and pI can be calculated from pKa1 and pKa3. Structure B of Cys, pI = (8.33 + 1.71) / 2 = 10.04/2 = 5.02 pH above its pI the Cys will be -vely charged (deprotonated) while pH below its pI it will be +vely charged (protonated). So, selection of buffer depends on its pI values, not pKa values of each functional group, QUESTION: What are the buffer regions/effective pH range?

The diversity of functional groups on sugars that can form glycosidicbonds greatly increases the information content of glycans relative to oligopeptides. Consider three amino acids, A, B, and C. How many tripeptides can be formed from one molecule of each amino acid? Now considerthree sugars—glucose, glucuronic acid, and N-acetylglucosamine. Use shorthand (e.g., Glcα(1 → 4)GlcUAβ(1 → 4)GlcNAc to represent 10 trisaccharides with the sequence Glc-GlcUA-GluNAc. Is your list exhaustive?
