Hi, I am currently studying for my mocks which are in two weeks and I finished all my revision notes but I need help with bonds. I just get confused at which bonds I need to remember and where the occur e.g. Peptide bond between two amino acids makes a polypeptide.

So, can you please tell me all the bonds I need to know and where they occur
Thank you

Ester bonds in triglycerides
Hydrogen bonds with DNA bases
Phosphodiester bonds for sugar phosphate backbone in DNA nucleotides
Peptide bonds in proteins
Glycosidic bonds between monosaccharides
Also you've got disulphides bridges, ionic, covalent bonds between R groups in tertiary structure of proteins.

Awesome, but what about the polymere bonds of the synthetic materials? did you not count them, as they don't occur in nature?

I've just finished OCR biology a level and this is what I was taught.

Do you mean polyamides and polyesters?

I was not aware of you just finishing OCR. Are you teaching in chemistry for higher levels anyway?

Yeah, polyamides and polyesters are synthetic materials just to name but a few.

Yeah, I know. I am afraid, it is a misunderstanding, so I am asking again and clearer: did you have choose chemistry for A levels? did teacher have teach you at this level?
