Biomolecules Class 11 Biology One shot for NEET 2025

2:7:31 mam in phospholipid str. In the choline group only 1 H from OH and another 1 H from CH3 coming out it means only H2 coming out ...then what type of bond it is mam ...can u please tell me

[@NACBiology]

In phospholipids, the choline group has a hydroxyl (-OH) and a methyl group (-CH₃). When the choline group connects to the phosphate, it loses one hydrogen from the hydroxyl and one from the methyl, forming a bond. The type of bond formed here is a phosphoester bond between the phosphate and the choline. This bond is a result of dehydration synthesis, where water is removed (in this case, two hydrogen atoms). So, you have a covalent bond formed, linking the choline to the phosphate group.

Ok thankyou mam

[@munirajum1863]

2:17 ❤ thank you for admiring mam😊

[@VidhyoshaPerumalla]

3:4:12 mam valine also neutral only know mam ...you have given 3 examples of neutral Amina acid that is alanine ,valine , and glycine then why not (a) option

[@NACBiology]

Thanks for the correction. Yes, valine is also neurtral so both option a and c is the right answer. Serine is classified as a polar amino acid, not a neutral one

[@VidhyoshaPerumalla]

3:11:39 yes mam we have no fear in biology...I will crack neet in 2025 and I proudly say that my biology teacher is always neelavathi mam ..❤❤❤❤❤

[@NACBiology]

thank you. Study well. Good luck

[@VidhyoshaPerumalla]

Thank you mam ..❤love from Telangana ❤

[@PoojamPari]

Please make video on all remaining chapters possible as early plzz mam..... especially plant philosophy..plzzz make videos fast mam ..I love ur teaching & best one ..form Davanagere

1:10:38 mam wrote OHC⁵H² that is wrong or what in text book they have given this OHCH²

[@NACBiology]

@@Bhavish-zm5fj That is CH2 only. But to show the number of carbon atoms, I have written 5 there. Actually i have mentioned that ,it is 5th carbon atom . It's not C5H2.

[@VidhyoshaPerumalla]

mam you said only right handed helix form protein ...but now you are saying 3:52:20 both left hand and right hand can observe....I didn't understand please explain difference mam

[@NACBiology]

please mention the timings where exactly i told "right handed helix form protein". for this question answer is right.

[@VidhyoshaPerumalla]

3:25:52

[@NACBiology]

@@VidhyoshaPerumalla Yes, left handed helices are very very rare in nature less than 1% . And no biological functional protein occurs in left handed helix form. Therefore in general we say like that. But. When question comes, both right and handed and left handed, then you can go for both. But when question asked biological functional protein which selected by nature are in which form? Then stick on to only right handed helix.

[@VidhyoshaPerumalla]

Ok mam thank you ❤

[@VidhyoshaPerumalla]

Mam one more doubt please 3:18:37 Is it in the same sequence every time or did you take it as an example?

[@AishwaryaLudhiaMallapuram]

From Bangalore ma'am:

[@NandithaNayak-o6w]

Mam,how many nucleotides per one turn of DNA double helix?

[@NACBiology]

One complete turn of the DNA double helix consists of about 10.5 base pairs. Since each base pair consists of two nucleotides (one on each strand), there are approximately 21 nucleotides in one turn of the DNA helix.

[@NandithaNayak-o6w]

@@NACBiology Thank you mam🙏

Mam in kannada biomolecules is 4hr and in english it's 7hr Does kannada lecture is enough

[@NACBiology]

In kannada, limited to NCERT only. But in English told little bit extra with diagram and solved MCQs.

[@Boss-b8z]

@@NACBiology Mam now which is better

[@NACBiology]

Your wish. Concept wise both are good. Given little bit more info thru diagrams + Solved MCQs in English videos.
