Question

WHICH COMBINATION OF BIOMOLECULES ARE IN TOAST, PEANUT BUTTER AND MILK

Answer 1

Short answer: all three contain the major biomolecule classes — carbohydrates, proteins and lipids — plus water, vitamins/minerals and small amounts of nucleic acids and other minor bioactives. Below is a concise breakdown by food:

- Toast (bread, toasted)
- Major: carbohydrates (starch, some simple sugars)
- Protein: gluten (wheat proteins)
- Fiber: insoluble and soluble plant polysaccharides
- Lipids: small amount from flour or added spreads
- Micronutrients: B‑vitamins (thiamine, niacin, folate in enriched bread), iron, sodium
- Other: water, trace nucleic acids

- Peanut butter
- Major: lipids (mostly triglycerides — mostly unsaturated fats)
- Protein: peanut proteins
- Carbohydrates: some sugars and fiber (insoluble)
- Micronutrients: vitamin E, niacin (B3), magnesium, phosphorus, potassium
- Other: phytochemicals (polyphenols), salt (if added), water, trace nucleic acids

- Milk
- Major: proteins (casein and whey)
- Carbohydrates: lactose (milk sugar)
- Lipids: milk fat (triglycerides, saturated and unsaturated fats; also phospholipids)
- Micronutrients: calcium, phosphorus, vitamin B12, riboflavin, vitamin A (and D if fortified)
- Other: water (major component), enzymes, immunoglobulins, trace nucleic acids

If you want, I can list the dominant macromolecule for each food (toast = carbohydrate; peanut butter = fat/protein; milk = protein + carbohydrate) or give approximate macronutrient percentages.
