Predict the order of the melting points of triglycerides containing fatty acids, as follows: From lowest to highest melting point Drag and drop your selection from the following list to complete the answer: linolenic, lauric, palmitic palmitic, palmitic, stearic palmitoleic, linoleic, oleic
The carbohydrates (CHOs), with a general formula of (CH₂O)n, are rich in hydroxyl groups. This allows the carbohydrates incredibly diversity of structure and function. Match the structural feature with the functional feature allowed. CHOs are useful for fast energy production. CHOs are widely used to mediate molecular recognition events. CHOS are widely used as structural materials. 1. 2. 3. Hydroxyl groups can interact extremely well with water. Hydroxyl groups can be extensively derivatized and functionalized. Hydroxyl groups allow CHOs to form extensive H-bonded networks.
The structure below includes both carbohydrate and lipid portions. A. Circle the portion(s) of the molecule above that would fall in the carbohydrate category. Explain how you can tell that the portion you circled is carbohydrate. How many saccharide monomers are present? B. Would the molecule above work well as a membrane lipid? Explain your answer, using the terms we have learned in lecture and/or the text. You will need to include in your explanation a brief description of the features required for a membrane lipid. C. Are the carbon-carbon double bonds in the structure cis or trans? How does the presence of these carbon-carbon double bonds affect the melting point of this substance (higher, lower, or no affect)? Explain your answer, using term we have learned in lecture and/or the text.

Which of these statements about the tertiary structure of a polypeptide is(are) untrue? You may select more than one answer. The tertiary structure will be maintained when the solvent is changed from pure water to aqueous acetic acid. O The tertiary structure is determined in part by the formation of disulfide bridges. Hydrogen bonding interactions are responsible for formation of secondary structure but not tertiary structure, O The tertiary structure is rigid and unchanging. O Charge-charge (electrostatic) interactions can be important in the tertiary structure.
