Do lipids, proteins, or nucleic acids contain peptide bonds? Which one contains peptide bonds?
Peptide bond is formed between amino group ( $NH2$) and carboxyl group ( $COOH$) of adjoining amino acids. A protein molecule is a made up of large number of...

What are some examples of fatty acids?
Examples would be fats, oils, cholesterols, and steroids. Fatty acids are in fact carboxylic acids with long aliphatic chain, which can be saturated (containing only C-C single bonds) or...

How do you determine the $alpha$ and $omega$ ends in fatty acids? How do we get the $alpha$ and $omega$ series? And are MUFA's non-essential fatty acids?
Fatty acids have two "ends"; the carboxylic acid (COOH) group is on one end, and this carbon is designated as the $alpha$ (alpha) carbon. The other end of the molecule...

Are MUFA (mono unsaturated fatty acids) non-essential fatty acids? If yes, then why?
An essential nutrient is one that the body cannot make itself, which is required for normal biological function... in this case, essential fatty acids are fatty acids that must be...

How does the interaction of polar covalent bonds allow hydrogen bonds to form?
When hydrogen is bound to a strongly electronegative element, i.e. $O, N, F$, charge separation occurs as the heteroatom polarizes electron from the bond to acquire a partially negative charge....

What is the difference between covalent bonds, and hydrogen bonds?
The covalent bond formed between oxygen and hydrogen in water, or hydrogen and fluorine in hydrogen fluoride, or nitrogen and hydrogen in ammonia, or hydrogen and chlorine in hydrogen chloride,...

Are ionic bonds the strongest type of bonds?
TEND to have high melting and boiling points...why? Because ionic ARE NON-MOLECULAR...i.e. an ionic compound consists of an infinite array of positive and negative ions that are held together...

How are these ordered from strongest to weakest: hydrogen bonds,covalent bonds, ionic bonds, and van der waals interactions?
This is the conventional order. Ionic bonds are of course non-molecular interactions.

What is the test for the presence of unsaturated bonds?
$RCH=CHR + Br_2(aq) rarr R(Br)CH-CH(Br)R$ As an olefin, of course cyclopentene should undergo this reaction; cyclopentane should be inert. As a tip, when you do these things in the...

You have a sample of neon gas at a certain pressure, volume, and temperature. You double the volume, double the number of moles of neon, and double the Kelvin temperature. How does the final pressure (Pf) compare to the original pressure (Po) ?
The final pressure will double as well. If you use the equation, $PV = nRT$, to express the initial and the final states of your gas sample, you can...
