There are 20 different amino acids. what makes one amino acid different from another? different asymmetric carbons

Amino acids are molecules that have a carboxylic acid group and an amine, attached to a specific carbon atom known as the α carbon. There are 20 amino acids, and they are different from each other, in the sense that each has a different side chain, known as the R-group and this R-group is attached to the α carbon.

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
