Sample interview questions: Can you explain your knowledge of the chemical composition of different food groups?
Sample answer:
Carbohydrates
- Monosaccharides: Simple sugars with one sugar unit, such as glucose, fructose, and galactose.
- Disaccharides: Two monosaccharides linked together, such as sucrose, lactose, and maltose.
- Polysaccharides: Large, complex carbohydrates composed of many monosaccharides linked together, such as starch, cellulose, and glycogen.
Proteins
- Amino acids: Essential building blocks of proteins, containing an amino group, a carboxyl group, and a side chain.
- Polypeptides: Chains of amino acids linked together by peptide bonds.
- Proteins: Complex molecules composed of one or more polypeptides, folded into specific three-dimensional structures.
Lipids
- Fatty acids: Long hydrocarbon chains with a carboxyl group at one end.
- Triglycerides: Three fatty acids attached to a glycerol molecule, the main component of fats and oils.
- Phospholipids: Lipid molecules containing a phosphate group and two fatty acids, found in cell membranes.
- Sterols: A type of lipid with a four-ring structure, including cholesterol and plant sterols.
Vitamins
- Water-soluble vitamins: Vitamins that dissolve in water, such as vitamin C and the B vitamins.
- Fat-soluble vitamins: Vitamins that dissolve … Read full answer
