Water, amino acids, hydrogencarbonate ion (or bicarbonate ion) HCO − 3, dihydrogen phosphate ion H 2 PO − 4, and hydrogensulfate ion (or bisulfate ion) HSO − 4 are common examples of amphiprotic species. Since they can donate a proton, all amphiprotic substances contain a hydrogen atom. Also, since they can act like an acid or a base ...

The bicarbonate ion carries a negative one formal charge and is an amphiprotic species which has both acidic and basic properties. It is both the conjugate base of carbonic acid H 2 CO 3; and the conjugate acid of CO 2− 3, the carbonate ion, as shown by these equilibrium reactions: CO 2− 3 + 2 H 2 O ⇌ HCO −
Various foods. This is a categorically organized list of foods. Food is any substance consumed to provide nutritional support for the body. [1] It is produced either by plants, animals, or fungi, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, and minerals.

The lipid bilayer, the material that makes up cell membranes. Phospholipids, a class of amphiphilic molecules, are the main components of biological membranes.The amphiphilic nature of these molecules defines the way in which they form membranes.
This is a list of antioxidants naturally occurring in food. Vitamin C and vitamin E – which are ubiquitous among raw plant foods – are confirmed as dietary antioxidants, whereas vitamin A becomes an antioxidant following metabolism of provitamin A beta-carotene and cryptoxanthin.
A nutrient is a substance used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals , plants , fungi and protists . Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures such as hair , scales , feathers , or exoskeletons .
