- Peptide Bond 1) Carbon, hydrogen, and oxygen from sugar molecules may combine with other elements to form other biomolecules. The picture above shows an example of this. Examine the model and choose ALL of the statements that accurately describe the formation of the new biomolecule. es A) Proteins are being formed. B) The monomers are amino acids. C) This is a hydrolysis reaction. D) Carbohydrates are being broken down. E) This is a dehydration synthesis reaction.

This depends on its physical and chemical properties that are affected during food processing, storage, preparation and consumption. For example: A. Bakery: the viscosity and the ability to form dough is related to the proteins of wheat gluten. B. Meat products: texture and succulence are dependent on water soluble meat proteins C. Dairy: texture and curd properties of dairy products are due to the colloidal structure of casein micelles D. Cakes (cakes) and desserts: depend on the foaming and gelling properties of the proteins in the egg white E. All are correctarrow_forwardIn this time of COVID-19 pandemic, a communicable disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), health experts suggest an optimal intake of nutrients plays crucial roles in boosting the immune system. Concerning your knowledge on biomolecules, how do eating carbohydrates and lipids improve our physical health in combating COVID-19 and other communicable diseases?arrow_forward

GPI anchor b. glycolipid c. glycoprotein d. glycoconjugate e. proteoglycanarrow_forwardWhich of the following statements about amino acids is true? A. Twenty two amino acids are commonly found in proteins. B. Amino acids are often linked together to form branched polymers. C. All amino acids contain an NH2 and a COOH group. D. Most of the amino acids used in protein biosynthesis have charged side chains.arrow_forward
- Name the 4 major classes of biomolecules used to make up living creatures and what types of things do humans use them for?arrow_forwardDefine the following terms:a. sterol carrier proteinb. fatty acid binding proteinc. biotransformationd. de novoe. turnoverarrow_forwardIn studying a particular biomolecule (protein, nucleic acid, carbohydrate, lipid), a biochemist needs to separate/ purify it from other biomolecules in the sample. However, looking at the monomeric subunits of a biomolecule, one should have an idea about the characteristics of the molecule that would allow to separate/purify it from other molecules. On what basis can you separate: a. amino acids from fatty acids? b. nucleotides from glucose?arrow_forward
- John has been living in an apartment all junior year, eating a lot of fast food. He has heard that it is "bad for you" because it is too high in calories and too low in essential nutrients, particularly vitamin A. John looks up the nutrient composition of two of his favorite fast-food meals (see table). 1. If John chooses the Big Mac, fries, and soda, for lunch, how many micrograms of vitamin A would he be consuming? (Hint: You first need to convert % Daily Value to micrograms of vitamin A.) Vitamin A Energy (% Daily Value) (kcal) McDonald's Big Mac 540 Medium fries 380 0.2 oda (20 oz) 240 KFC Fried chicken thigh and breast 690 2.6 Mashed potatoes and gravy 120 1.5 Soda (20 oz) 240 *Hint: first you need to look-up the daily Value for vitamin A: 900 µg (I just gave you the Daily Value). For dinner, John has 2 cups of spaghetti with meat sauce, a slice of Italian bread with 1 tsp butter, and a cup of 1% milk. 2. How much vitamin A does this provide?
