Are amino acids polar or non polar? I read that they're non polar but it depends on their R group however on a mark scheme it says amino acids are more soluble in polar solvents suggesting that they themselves are polar?
If the amino acid had two NH2 one as the variable group and one was the amino group and you reacted it with H2SO4. Would you only need 1mol of the acid then?
For the formula of an amino acid, can I write H2NCH(R)COOH instead of the formula in your video?
Is it ok to put the r group on top when drawing the isomers?
Yeah
Hello sir just to confirm it dosnt matter which order we out each group for the optical ismomers 1:55
Correct

Sinead Ryan Polar. They have a COOH group

yes because the H2SO4 can donate two H+ ions. so each amine group gets a H+ ion
do we need to know how to name amino acids like serine?
No, just the systematic names of the simple ones e.g 2-aminopropanic acid
Hi, do we need to know anything about the isoelectric point?
Not on the new spec. Zwitterions have gone too if you were wondering?
@@MaChemGuy Okay thanks!
Do we need to know about zwitterion?
Sir Not any more
Do we not need to know that it’s called the isoelectric point instead ?
is this for OCR ?
Aaliyah Parkar yup
