- Tridecane [CH3(CH2)11CH3] is a major component of the repellent that the stink bug Piezodonis guildinii releases from its scent glands when attacked. What fatty acid gives tridecane on decarboxylation?Briefly explain why chicken fat, which largely consists of various triacylglycerols, has such a higher energy content per mole compared to sucrose.Disadvantages of cholesterol
- not a possible value for the number of monosaccharide units in an oligosaccharide?True or False a. Branching decreases the solubility of glycogen. True False b. The branching enzyme forms the α-1,6 linkage in glycogen. TrueFalseThe 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?
