The definition of the following biological terminology: (a) gene (b) mutation (c) hydrocarbon (d) hydrophobic (e) hydrophilic Introduction: The genetic information of organisms is stored in the form of genes. Sometimes, there is a change in the properties of the genetic material, this may be because of mutations. Compounds with carbon and hydrogen molecules are hydrocarbons. Molecules can either be hydrophobic or hydrophilic in nature.

Question

Two tetrapeptides were isolated from a possum's sweat glands. These peptides were sequenced using Edman degradation and the following 2 sequences were obtained: Gly-Asp-Ala-Leu Gly-Asp-Asp-Leu Can you please help show the titration curve for both of these peptides and calculate the PI?

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .
