name some iving biomolecules
one example: Adenosine diphosphate (ADP)
is it living one?
i don't want definition .i want example of living biomolecules
here are the examples: proteins, polysaccharides, lipids, and nucleic acid
yes these are living things
is it living biomolecules?
define "living"
Think as aaronq you should try define living. Molecules are molecule, but we can go down into chemistry history and look upon a concept that come close to your idea: Around 1800 a theory was made. it was the theory of the simple proportions seem not to apply to compounds isolated from plants and animals. The theory of "living force" that the molecules from plants and animals where made living by this "living force" However in 1811-1823 chemist were able to convert fat molecules into glycerol and fatty acids (saponification) outside a organism - that is without using "living force" in 1828-1831 chemist manged to create urea ( (NH2)2CO ) from the inorganic ammonium (NH4+) and cyanate (-OCN). This as well was done outside a organism and the theory of "living force" had to be dropped.
I think the person was confused if proteins, lipids, and other biomolecules were considered living and they are the workhorses for living things.
actually a "living biomolecule" is DNA/RNA,because those are known smallest thing that can replicate themselves,can bear a definite code,which can later inform any cell to produce important proteins,help regulating cellular metabolic activity,also our whole body system activity.so we can say anything made up of protein/you can say amino acids is "living",take example of virus,they act like a living thing only inside a host,but made up of Amino acids,or you can take also enzymes.so anything made up of protein can be taken as "living"
^ DNA can't replicate itself, the work is done by enzymes. I don't consider viruses living as they don't have true metabolic processes.
all i m saying any metabolic activity is controlled by enzymes,and every enzm is made up of protein,which are macromolecule of amino acids,and DNA have replicating property,enzymes help them in that process.and viruses are considered living inside a host as by scientists,that is why they are belong to the connecting link between living and non living.main characters of living is to reproduce one's progeny which will continue bearing genetical codes through out life-cycle.virud can do this with the help of host machinery and host's organelles,and also any virus can chance their strain by recombination,increasing resistivity.that is why flu can be eradicated,it keeps changing its strain,like H1N1,H2N2...etc.
proteins can be taken as a living biomolecule,because the first organism on earth was a protein named protobiont,which later transformed into microsphere.it has repllicating properties.
"The stuff of life" some good thinking worth considering in this conversation. http://www.ted.com/talks/lang/da/lee_cronin_making_matter_come_alive.html
The smallest unit of life is a cell, yes? And if that's true, then how could a living molecule even exist?
