a C-H bond
The organic elements are
C, H, O, N, P, S
Organics are generally complex molecules, such as

Organic elements make up ___ percent of body mass
97
Most of the macromolecules in our body are
proteins (17% body mass) or lipids (15%) body mass
Inorganics are generally ____
salts. AKA: electrolytes. Don't forget that H2O is an inorganic molecule
Major inorganic elements of the body include
Na+, K+, Ca2+, Cl-, and Mg2+ (all together make up about 3% body mass)
The inorganic molecule mostly found INSIDE of the cell is
K+ (about 140 mOsmol) and Mg2+ (31 mOsmol)
The inorganic molecules mostly found OUTSIDE of the cell are

covalent bonds (non-polar and polar), ionic bonds, and hydrogen bonds
Hydrophilic (charged or partial charged) examples are
water, inorganic ions, nucleic acids, carbohydrates, and proteins
Hydrophobic (non-polar) examples are
fats, cholesterol, and proteins
The definition of amphiphilic is
a molecule that contains both hydrophobic and hydrophilic domains
